Show HN: Evera Labs – DNA file storage/quantum computing decentralized network https://ift.tt/2U6wSMp

Show HN: Evera Labs – DNA file storage/quantum computing decentralized network Hi HN - We are Nabeel, Zeel, Michael, Munish and Kanika of Evera Labs ( https://everalabs.com ). We are creating the world’s first integrated computing and file storage network powered by DNA file storage and quantum computing. Quantum computing bolsters the speed and security of our network, while our novel DNA encoding and decoding models allow for DNA file storage at a commercially viable scale and allows our network to be cheaper and faster. Our blockchain microtransaction system incentivizes network integrity. Evera Labs takes the best elements of the ethereum mainnet and combines them with distributed computing and file storage, all while being powered by the computing infrastructure of the future. While we offer private computing and file storage, users may push their data to our public research repository for a reduced rate, therefore incentivizing open-access research. Developers and researchers can use our network to scale DAaps and perform computation with big data respectively. The founding team consists of three Harvard undergrads (Nabeel, Zeel & Michael) who contribute to the scaling of our blockchain, DNA file storage, quantum computing and financial goals as well as two Ph.D students (Munish (biophysics) & Kanika (biochemistry) who are skilled in DNA based file storage and lead our research initiatives. While we are building our decentralized network with our development team, we are launching our first set of products that are set to drive network development. Our DNA file storage product ($200) allows users to enter their name and a short message, have that information be encoded in DNA, synthesized and sent to them while we also offer an early network pass ($2) that users can use to receive a 50% discount upon network launch. We would love to hear any of your ideas, suggestions and comments as well discuss the blockchain space as well. We are super excited to be launching here and can't wait to hear from you :) The Evera Labs Team April 1, 2019 at 02:30AM

Show HN: A Site to Provide Better Explanations to Coding Interview Problems https://ift.tt/2Ul70f9

Show HN: A Site to Provide Better Explanations to Coding Interview Problems Hi all, Late last year, I did a round of interviews with big tech companies. During preparation, I realized that there were tons of sites with whiteboarding interview questions, but not a lot of well-explained ones. I decided to build https://algodaily.com , intended to be the easiest place on the internet to prepare for technical interviews. Every challenge is walked through step by step, and includes quizzes that help with recall. Every challenge is written in JS, which is IMO the best language for new programmers since it can easily be run and tested in the browser. I also recently wrote this article about technical interview prep: https://ift.tt/2uDLCTG... I encourage you guys to check out the site and leave feedback. It would be greatly appreciated as I try to build a better resource for web developers who want to level up! March 30, 2019 at 09:55AM

Show HN: A good excuse to explore that side project idea If you're like me, you have at least a half-dozen (half-baked) ideas for side projects sitting on your "idea shelf" waiting for the right opportunity to come along and give you that spark to get started. At my day job (Bridge.Academy), we found that many of the incoming developers entering our program shared the same experience so we decided to do something about it and formalize the process of picking up a new technology you are trying to learn and applying it through a side-project with a program we're calling "The Bridge Tournament". It's designed to give you that extra bit of motivation to take your side project idea off the shelf, pick up a brand new technology and start building the damn thing. Here’s how it works Each month new applicants to join Bridge.Academy participate in a tournament in order to demonstrate their ability to quickly pick up new skills through working on a project of their choosing. Applicants receive points based on their progress. The more impressive your pace of improvement, the higher your score will be and better your chances of winning. The Process Submit your application · Due this Sunday. You’ll describe yourself and your project. Vote on projects · Monday. Other applicants & Bridge Mentors will also vote on your application. Applicants will only see some of your responses. Submit weekly updates · Due every Sunday. You’ll submit a progress update once a week. Vote on updates · Every Monday. Get points from other applicants based on your progress. The more impressive your work, the higher your score will be. More on the process here: https://ift.tt/2HJvbxL... You can read more about how the tournament works and find links to apply here: https://ift.tt/2OsKPhz... March 27, 2019 at 01:17AM

Show HN: Songcraft – Online Songwriting Platform and Guitar Tab Builder https://ift.tt/2JnIN3s

Show HN: Songcraft – Online Songwriting Platform and Guitar Tab Builder Hi HN! I'm Gabe, the creator of Songcraft ( https://ift.tt/2Oe8G4J ). I recently dove headfirst into songwriting, and I quickly grew frustrated with my process. I found songwriting difficult enough without having to wrangle a mess of different tools, and there's no great solution to build chord sheets and tabs (unless you love pure text input). So, I built Songcraft - an online songwriting platform and tab builder. The drag-and-drop editor makes it easy to jump from chords to lyrics to melodies. I added a chord progression generator and chord recommendation engine to ensure the ideas keep flowing. The integrated tuner, rhyming dictionary, metronome, and audio recorder allow you to stay focused without distraction. A few months ago I shared the beta on Hacker News and got some incredibly helpful feedback and some amazing beta users. Since then, I've revamped the product and made a ton of improvements and additions. Today is launch day, and I wouldn't be here without Hacker News! I'd love to hear your thoughts and answer any questions you may have. Drop a line here or at gabe@songcraft.io. March 20, 2019 at 09:51PM

Launch HN: Cliperado – Automatically take screenshots of your whole service https://ift.tt/2FhJyWm

Launch HN: Cliperado – Automatically take screenshots of your whole service Cliperado ( https://cliperado.com ) is an online tool to automatically take screenshots of your service and keep the shots up-to-date in your help guides. The idea for Cliperado came when we were creating visual step by step guides, to reduce our support volume, for an other service. We needed about 200 clips for each language. It took so much time to create just a few. I was pulling my hair out. Especially with the thought of having to check all the clips for changes in a month from now, manually. You’ve probably seen a few online tutorials with outdated and confusing screenshots. You probably have a some outdated screenshot in your own manuals. I get that, it is just too much work to keep these updated manually. So we created Cliperado, to automate this. How Cliperado works. Cliperado takes full page retina screenshots of your online service. It can take screenshots of pages behind a login screen as well, by filling out forms, clicking on buttons or hover over menus, etc , etc. You can crop a screenshot, add arrows or highlights, to create clips for step-by-step guides. Cliperado hosts these clips online. You can schedule Cliperado to refresh the screenshots weekly. Changed screenshots are highlighted in the visual sitemap, so you don’t have to hunt down changes. When you expect a screenshot to change with every refresh, you can mask certain areas, to exclude these from comparison. We hope you want to give Cliperado a try. We are looking forward to your feedback. March 20, 2019 at 03:38AM

Launch HN: Nabis (YC W19) – Cannabis Shipping and Logistics https://ift.tt/2uaj5VN

Launch HN: Nabis (YC W19) – Cannabis Shipping and Logistics Hi HN! We’re Vince and Jun, the founders of Nabis ( https://ift.tt/2UKLnlz ). We are building a software and infrastructure solution to ship legal cannabis products for brands to licensed dispensaries throughout California. About two years ago when the legalization of recreational cannabis was pending in CA, we were excited as consumers to be able to try out a variety of products without having to get a medical card. While we knew that many more brands were coming to market, we discovered that there was a lack of supply chain infrastructure to support the growing demand. We started out driving our own personal vehicles across the state to help a friend ship his products just to learn more about how the supply chain was set up. We learned that brands were still predominantly self-distributing, since you can’t just Fedex cannabis products due to compliance restrictions. Apart from shipping, the lack of secure warehousing space, a ubiquitous cash-based payment system, and vague new regulatory language all created massive friction to building a sound and cost-effective supply chain for cannabis products. Once we started shipping more orders than we could deliver ourselves, we hired a team and built out a web portal that automates the most tedious parts of our operations, especially with regards to compliance and paperwork for shipping, storing, and testing cannabis products. We wanted to help scale the growing cannabis industry that was about to legalize, and convert more of the illicit black market into the legal market. When recreational legalization commenced in January 2018, we applied for our distribution license since that would allow us to continue building our business as the logistics backbone for the industry. We thought distribution was the best place to start as it sits right at the center of the supply chain as the final checkpoint before products are sold into the retail market. By scaling out distribution, we help drive down the costs for everyone in the industry due to the economies of scale that we can achieve by owning one set of infrastructure for multiple brands, rather than having each brand build out its own delivery and warehousing solution. Today, Nabis tracks and delivers over 1,000 SKUs for nearly 40 of the largest brands to 90% of retail dispensaries in California. The data that we track gives us insights into the cannabis market as it continues to grow rapidly, providing data-driven metrics of what brands and product categories will perform best in the market. We want to continue to support as many products that consumers love by ensuring reliable shipping and logistics of products to retailers. By expanding our infrastructure and portfolio of brands, we’re hoping to achieve our ultimate goal of scaling cannabis access to the masses and become the widest distributor of cannabis products. Thanks for reading and hope that you continue to support the legal cannabis market! We’re looking to build a community of technologists to grow a data-driven supply chain for the cannabis industry, so we’d love to talk to you if you’re interested in working with us. Also, if you're well-versed in logistics and working in regulatory landscapes, we'd love to hear from you. And we're very curious for feedback in general! Looking forward to comments, and you can also email us at founders@getnabis.com. March 16, 2019 at 10:42PM

Launch HN: Bottomless (YC W19) – Coffee Restocked with a Smart Scale https://ift.tt/2Hpu7yV

Launch HN: Bottomless (YC W19) – Coffee Restocked with a Smart Scale Hello, HN! We're Michael and Liana, co-founders of Bottomless ( https://bottomless.com ) Bottomless automatically re-stocks coffee using a smart scale. Users leave their coffee on the scale, then we detect the perfect time to trigger re-orders. We ship the scale for free when customers buy their first bag. We met in college, and bonded over talking about businesses we could build together. You could say we've kept in touch since then: we're now married. Bottomless was born out of our frustration managing our household stock levels. We always seemed to be running out of one thing or another. When we thought about it, we realized that restocking was a universal problem. But if this was such a big problem, why was there no great solution? Subscriptions should be a solution, but they don’t work well for items that aren’t used on a set schedule. It seemed that if we could capture data on usage and stock levels in a passive way, we could solve the problem. Thus, Bottomless, the concept, was born. The market for stuff people repeatedly buy is enormous. (We'll leave an exact estimate up to the reader's imagination.) We decided that to start we'd establish a beachhead with a single market. We landed on selling premium coffee because it's cheap to ship and has good margins. It also is much better shipped straight from the roaster than bought at the grocery store. In the beginning, we built the simplest thing possible to test if the concept would work. We hacked together a scale prototype, made five of them and got them into the hands of friends. We bought coffee from roaster websites with our customers’ addresses to bootstrap supply. The goal was to test if people would leave their coffee on a scale, and if we could reorder at the right time. It turns out they would and we could! Since then, it's been a matter of making larger batches of scales. We bought a few 3D printers and acquired quite a few burned fingers from soldering. We've benefited from a few technological tailwinds. For one, smartphone supply chain has driven down the cost of components quite a bit. We've been able to build hardware that works for this business model out of super cheap WiFi modules and LiPos. Also, the level of open source software for ML is quite powerful and well-documented. We're aware that we are just scratching the surface of re-ordering hardware. We'd be interested to hear ideas that the community might have about this space! March 16, 2019 at 01:32AM

After being fed up with the poor customer experience and tactics of traditional banks, we did some digging into why we put up with our own subpar banks. We've discovered that the way most people end up with their current bank is by default (ex: parents set it up for them), rather than by choice. The complete opposite was the case for credit cards; credit cards were actually chosen based on their qualities. We began to wonder why a solution that combined the rewards and benefits of a credit card, with the simplicity of a bank account didn’t exist. After extensive research and testing of various existing products, we determined that everything came up short for our personal needs. That was the problem. Whether it was simply the lack of a clean mobile user experience, or rewards that were relevant, nothing managed to fit the bill. Since banks are a fundamental part of our everyday modern lives, we shouldn’t have to settle for a less-than-stellar experience just because that’s the current standard. That’s when we realized, we don’t have to settle. This was an exciting enough realization for us all to quit our day jobs as product managers, designers, and engineers. We decided we needed to create a revolutionary bank. In order to solve this problem, we created a new-and-improved debit card. We are focusing our efforts on debit because it is currently the most popular payment method. Although debit is the preferred method, in the real world, there is little incentive to use one over the perks offered by credit cards. This unfortunately leads the majority of the dissatisfied group to settle for credit cards, with their offer of limited perks that typically come hand-in-hand with unavoidable debt. Our business model is sustainable because we are partnered with a smaller regional bank and don’t have the hefty over head of a branch network. The reason we don’t see larger banks offering debit cards with rewards is because of the "Durbin Act”; a federal mandate which slashed interchange margins of banks with more than $10 billion in deposits. This was done in order to protect consumers and merchants from increasing and predatory prices that banks were trying to instill. If successful in our mission we hope to keep the up and comers out of un-necessary credit cards and raise the standards of user experience for banks. There is no reason why dealing with your bank should be as dreadful as the DMV. We look forward to hearing your thoughts on what we are building and are open to any and all suggestions.

Launch HN: Nala (YC W19) – Internet-Free Mobile Payments App for Africa https://ift.tt/2JeCyiB

Launch HN: Nala (YC W19) – Internet-Free Mobile Payments App for Africa Hi HN! I’m Benjamin, one of the co-founders of NALA ( https://www.nala.money ), an application that simplifies the process of making mobile payments for our users in Africa. My co-founder Sam and I first met back in 2016 while I was working at the Bill and Melinda Gates Foundation (focusing on financial services in Africa), and he was earning his Ph.D. in computer science at the University of Washington (researching mobile money security in Sub-Saharan Africa). As you may know, the way that mobile payments are made in many developing markets is quite different from how they're made in the rest of the world. In much of Sub-Saharan Africa, people make payments using mobile money, an electronic wallet service that is typically tied to a user's cell phone carrier and sim card. Using a 39-46 digit sequence of short codes (i.e. dialing a code such as 150 30, waiting for a screen to pop-up, dialing another code and waiting for that screen, repeat, etc.) that are received by the user's cell phone carrier, a user can request to send money to a friend, pay a bill, or purchase airtime all without being connected to the internet and accessible via smartphone and basic feature phone alike. (M-Pesa, which you may have heard of, is just one of the many such mobile money services offered in Sub-Saharan Africa). While mobile money has undoubtedly transformed the way that millions of people transact, the process of executing a mobile money payment is time-consuming, arduous, and prone to error, resulting in a less than ideal transactor experience. After moving back to my home country of Tanzania in 2017 and conducting 700+ on-the-ground interviews, Sam and I founded NALA, the first internet-free mobile money smartphone application. NALA interfaces with existing mobile money providers (M-Pesa, Airtel, tiGO etc.), and provides users with a simple Venmo-like payment experience. To deliver this capability, NALA has built a USSD automator tool to send requests over existing USSD channels. Our product serves as a central platform where users can initialize payments for all of their mobile money accounts (having multiple sim cards and mobile money accounts is extremely common in Sub-Saharan Africa as inter-network transaction fees are lower than out-of-network fees), and for the first time ever, access their transaction histories through our rich transaction tool. While we will make a percentage cut for every bill payment and airtime top-up that is conducted on our platform, we are primarily focused on growing our active user-base. As Sub-Saharan Africa mobile money usage proliferates ($860+ million in daily transaction values and close to 400 million mobile money accounts), smartphone penetration approaches 40%, and the fastest growing middle class of any continent comes into its own, we believe there is massive potential to transform and shape the African payment space. Building a product that thoughtfully addresses our users' financial challenges is what excites and energizes us. The pernicious transaction fees that mobile money users are subject to is an area of particular interest and focus. We would love to hear about HN's ideas and experiences in this space, as well as answer any questions you might have! March 15, 2019 at 02:35AM

Show HN: C++17 In Detail, a book that will move you from C++11/14 to C++17 https://ift.tt/2UBd3sN

Show HN: C++17 In Detail, a book that will move you from C++11/14 to C++17 Hi! Last year in August I've released my first self-published book. C++17 In Detail Available at Leanpub: https://ift.tt/2LgTiRU Keeping up with the latest changes in the language is quite hard. C++ moves quite fast recently, and there are many exciting features added with each iteration. The book shows all the significant changes in the language and the Standard Library. The chapters are much easier to grasp than reading reference pages or the Standard itself. It's a great guide for any C++ developer who knows a little about C++11/14 and wants to move forward. In August the book was 90% ready, and I worked since then to write the last chapters and improve the content. In March it reached finally the 100% status :) I would appreciate any feedback! You can also ask me about the publishing process. March 14, 2019 at 11:17PM

Launch HN: Travelchime (YC W19) – Doc for travel planning with friends https://ift.tt/2O6xdso

Launch HN: Travelchime (YC W19) – Doc for travel planning with friends We're Peter and Harry, and we're building Travelchime ( https://travelchime.com ). Travelchime is like Google Docs for planning vacation travel with your friends' recommendations. It lets you add places and attractions you're looking to visit to a doc, export them to Google Maps, and collaborate with your friends who've been there or are going there with you. We used to plan our trips using Google Docs and Sheets, but it was a pain. We'd write the documents, then had to add the same places to a map for when we're on the trip. We also often sent these out to friends who asked -- there's nobody whose recommendations you trust more than your friends -- but it's hard to find which friends have these docs. We built Travelchime to solve this. With Travelchime, you can: 1. Add all the museums, restaurants, and places you're staying/want to visit to a doc on Travelchime, and see them on a map with their opening times, links to Yelp, and more 2. Share the doc with friends on the trip or ask others for recommendations: multiple people can edit/suggest at the same time, just like Google Docs [1] 3. Export the places to Google Maps for when you're on the go 4. (Optional) Read some itineraries from around the web to get inspired! We use basic machine learning [2] to parse itineraries for the places they mention to help get you started 5. Once you’ve gone on the trip, you can share the full itinerary with notes to inspire your friends We haven’t monetized, but will eventually link out to hotels that work well with your itinerary and get affiliate commissions there. We've gotten a ton of support from Hacker News in the past: when Yale shut down our courses website, Hacker News rallied and got the attention on it to save it ( https://ift.tt/1m1R3RF ), and past HN launches (e.g., for WrapAPI: https://ift.tt/1UQiNfO ) got us our first paying customers. We love the direct feedback we get, so if you're planning a trip soon, give it a shot and let us know what you think either here or by email at peter@travelchime.com! [1] To enable real-time editing, we use Quill ( https://quilljs.com/ ) and ShareDB ( https://ift.tt/1Mdh2AB ), both amazing projects. We had also tried Draft.js, Slate, so if you want to chat text editing hit us up! [2] A combination of Google's Entity Recognition API, Google Maps' APIs, and human checkers [3] For those curious: we <3 React and have an all-Javascript stack with Node.js and MySQL on the back-end March 14, 2019 at 02:50AM

Launch HN: Superb AI (YC W19) – AI-Powered Training Data https://ift.tt/2O2N771

Launch HN: Superb AI (YC W19) – AI-Powered Training Data Hi HN, I’m Hyun, one of the co-founders of Superb AI ( https://ift.tt/2J9xifT ) in the YC W19 batch. We use AI to semi-automatically collect and label training data for tech companies, and help them implement machine-learning based features faster. Almost all the magical AI features that we see are actually built using training data powered by humans. Companies build software tools and farm out to a bunch of people to click and type things repeatedly to label the raw data. That's how training data is made, and that’s a very large portion of what an AI is, up to this point. It has worked well up to now, but the process is not very fast and often prone to error. Moreover, the size of training datasets has increased exponentially over the past few years, as it almost guarantees a higher AI performance. AI engineers are now handling datasets as large as tens of millions of images, and thus there is a great need for a better way to build training data. We started out as a team of five — Hyun (myself, CEO), Jungkwon (CTO), Jonghyuk and Moonsu (AI Engineers), and Hyundong (Operations), and after about a year, we are now a team of thirteen members. We have diverse and complementary backgrounds in robotics, computer vision, data mining, and algorithmic programming, and we all worked together at a corporate AI research lab for around two years. While working on various projects from self-driving to StarCraft game AI, we experienced first-hand how building the training data was one of the biggest hurdles for developing new AI-based products and changing people’s lives. We initially tried to solve this problem from an academic perspective and published a research paper on using coarsely labeled training data for machine learning [0]. Soon, we decided to work on a more practical and widely applicable solution to this problem and that’s why we started this company. So how do we use AI to solve this problem? There are largely two approaches we take. The first is, we try to automate as many pieces of the data building pipeline as possible using AI. To do so, we split the process into many smaller steps. If we take an image-labeling task, for example, putting bounding box labels around each object can be split into 1) scanning the image to find the type and location of each object, 2) drawing bounding boxes around each, 3) refining and validating all annotations. Some of these smaller task chunks can be completely automated using AI. For others, we build AI tools that can assist humans. And for really difficult ones, we do have human workers to do it manually. It’s a tricky problem because we need to understand what kind of tasks AI can do better than humans and vice versa, and carefully choose which tasks to automate. Secondly, we try to improve our AI components throughout a given data building project using a human-in-the-loop AI approach. The key is that we bootstrap and feed portions of the training data we make back into our AI so that we can fine-tune them on the fly over the duration of a project. For example, we may start a project with a baseline AI (“version 1”), and for every 20% of a particular training dataset we make, we iterate and keep fine-tuning our AI so that by the end of the project we will have AI “version 5" that is specifically trained for the project. So as our AI components improve, human contribution gets smaller and smaller over time, and in the end, we will need very minimal human intervention. Ultimately, we want to make it like how humans learn. We see others do something for a few times, and we quickly learn how to do it ourselves. As our technology improves, our AI will be able to learn from only a few examples of human demonstration. We found out that using AI in these two approaches not only makes the process faster but also more accurate. One of the reasons there is an accuracy problem with existing manual labeling services is that humans have to do too much. They spend hours and hours doing the same clicking repeatedly. But by us making it almost painless for humans to figure out what to do, they not only get through more data but they are not as exhausted or cognitively loaded. Our current customers, including LG Electronics, are from industries ranging from autonomous vehicles and consumer to physical security and manufacturing. A large majority of tech companies have a shortage of AI experts and need to develop machine-learning based features with a very limited number of them. As a result, these companies do not have enough resources to build their own automated data building pipeline and often rely on outsourced manual labor. We can deliver training data much faster and better than these vendors that extensively rely on manual labor. We are extremely grateful to have the chance to introduce ourselves to the HN community and hear your feedback. And we're happy to answer any of your questions. Thank you!

Show HN: Building computer labs in schools in Africa https://ift.tt/2HsXUpH

Show HN: Building computer labs in schools in Africa My name is Nelly Cheboi. I am the co-founder of https://ift.tt/2UuEmEZ , an organization that fosters a more technologically literate Africa by building computer labs in African schools. I was raised in Mogotio, Kenya, in abject poverty. At nine years old, I collected wild vegetables on my way from school to cook for my younger sister. The only way I knew out was by studying. So I studied. I studied hard. And I ended with a full-ride scholarship to Augustana College, IL. I was majoring in Chemistry before I discovered computer science my junior year of college. I loved it. With only three semesters left, I decided to get a degree in it. I also built a school with the aim of fostering digital literacy. I doubled down on my work-study program, got some donations from friends and four months later I launched Zawadi Preparatory (www.zawadiprep.tech). We admitted 30 kids at its launch in January 2016. Barely 3 years later, we are at 150 kids. In summer 2018, we built a computer lab at Zawadi Prep. We collected computer donations, bundled it with elementary OS along with open source education software. There is no broadband internet, so we downloaded terabytes of content for our local server including Wikipedia and Stack Overflow. We showed the villagers how to make a Rails app at our free after school program. I cannot think of a better success story than the one of my seven-year-old niece, Michelle. My friend came over to the lab. Michelle asked, "do you want to see our content?" They were like, "sure." She then opened up a computer, navigated to `192.168.0.2` and said, "look, we have all these." I teared up a little bit. I did not teach any of that. Our goal for 2019 is to build 10 more computer labs in 10 different Kenyan schools. I always wanted to end poverty. To me, teaching digital literacy is the best way I know how. We now have over one hundred donated workstations. To meet our goal, we need a few hundred more. https://ift.tt/2UuEmEZ March 13, 2019 at 06:04AM

Launch HN: Axdraft (YC W19) - Legal documents for startups in minutes https://ift.tt/2UwzXS1

Launch HN: Axdraft (YC W19) - Legal documents for startups in minutes Hi HN! We are Yuriy and Oleg, founders of Axdraft ( https://ift.tt/2XQ5ksW ). Axdraft offers free legal documents for startups. We have built Axdraft, because we believe that sometimes founders don’t need 20-page ironclad contract, 2 weeks of negotiations and detailed explanation of all risks. On early stages you just want to have a good, balanced agreement fast to move the deal forward while it's hot. The biggest difficulty here is that lawyers push us to perceive contracts as unique and, therefore, not possible to automate. Usually, by saying unique, they mean that there are 20-50 possible variations of a clause in the contract. We are a team of brothers, who combine legal and tech expertise, Yuriy was a lawyer for almost 8 years at one of top law firms in Europe and when he started noticing that even the most complex legal transactions have many patterns, he reached out to his brother Oleg, who at that time was Senior Software Engineer at Booking.com in Amsterdam. We teamed up to try to figure out and automate most common variations and allow any young startup, as ourselves to draft a document, which they need now. We spoke to about 100 founders and came up with a list of top-6 contracts startups use, including: (1) NDA; (2) Pilot agreement; (3) Services agreement; (4) SaaS agreement; (5) SAFE; and (6) Employee onboarding. We are already working on Terms of Service, Privacy Policy, Founders Agreement and LoI, which are top-4 documents requested by users. We will be more than happy to add other documents upon your request. Our main differences compared to Clerky, LegalZoom, RocketLawyer and similar solutions are: 1. we focus on startups, which makes the content more tailored; 2. we offer documents for free, because I see little value in the legal document itself. The main value of a lawyer, in our view, is in counseling, sharing the liability and providing you assurances; 3. we offer plain English description of the implications for each choice you are offered when drafting a document; 4. to use Axdraft you don’t have to register, because we want to create flawless and super-fast experience for founders to create legal documents; 5. we are happy to customize documents of registered users with their logos, company details and some custom language upon request. We intend to monetize Axdraft by giving an option for startups to submit any document drafted with Axdraft or a document they received from third party for approval or review by a lawyer for a small fixed fee, which would still be much more affordable than engaging a law firm. Currently, we offer founder to founder review, which is not a legal review at all, but more a business advice from a fellow founder, who is eager to share his experience with similar contracts. We estimate the market for this product to be less than 1 bln USD at the moment, but we expect it to grow as the number of startups founded each year increases and as we expand into a larger 7 bln USD market of small businesses (under 20 employees) in the US. We are really excited to hear your feedback about Axdraft. Please try it out at https://ift.tt/2SXiEIk (registration is not required) and let us know what you think. March 13, 2019 at 01:54AM

Launch HN: Latchel (YC W19) – Rental Property Maintenance as a Service https://ift.tt/2u2xrau

Launch HN: Latchel (YC W19) – Rental Property Maintenance as a Service Hi HN! We're Ethan, Jullian, and Will. We're the founders of Latchel ( https://latchel.com/ ). We handle 24/7 maintenance for residential property managers and landlords across the US. Ethan was Director of Product at One Planet Ops, the creator of websites like contractors.com, homegain.com, and many other lead gen marketplaces. Jullian is a self-taught developer and designer who has built mobile and web apps, most recently at picmonic.com. Will comes from Amazon, where he helped design and deploy the last mile delivery operations for Amazon Fresh, Prime Now, and Amazon Logistics across the US and the world. Will started the company when his family needed help running the family rental properties. His grandfather managed the properties full time all the way into his mid 90s! Sadly, his age caught up with him and he could no longer take care of the family business after getting diagnosed with Alzheimer's. The disease progressed quickly and unfortunately the family did not have a succession plan in place (advice to anyone with a family business: plan the succession early, you don't want to spend energy worrying about the family business when you want to focus on taking care of a parent's medical or end of life care). Will helped his father with the properties as much as he could while working full time at Amazon but was quickly overwhelmed by the maintenance dispatching and follow-up. He saw that the overall process was very similar to the logistics and delivery problems he was solving at Amazon. After looking for solutions online and calling Ethan to see if he knew of any solutions they couldn't find any. Ultimately, we teamed up to build what we couldn't find on the market: a service to handle rental maintenance problems and ensure work orders don't slip through the cracks. Maintenance coordination is a difficult problem to solve because it is fundamentally a communications problem that isn't easily solved by software. First, most contractors are third party and take jobs infrequently from a property manager, so they're extremely unwilling to adopt a new process for reporting work is complete or for getting paid. Second, tenants also interact with their managers rarely, so mobile applications (and even online portals) have low adoption rates among renters. Lastly, property managers face an agency problem--ultimately it isn't their properties, it is their clients who own the property. The property manager is responsible for its care and maintenance and want to be able to have all of the details of what happened and to know why certain decisions were made in case something went wrong. We sell monthly subscription services to property managers to take all of their maintenance calls. We have two paid subscriptions: 24/7 Emergency and a premium option where we handle both emergencies and non-emergencies. We also have a free software tier that gives property managers an online web portal for tenant maintenance request submission. This online submission tries to detect emergency scenarios and our software automatically calls the property manager in case of emergency. In addition to the monthly subscription services we also take a 10% referral fee from contractors we source for the jobs (we cover the credit card processing fees). The HN community is full of people working on simplifying the oftentimes ugly interface between the real world and idealized technology systems. We'd love to hear your questions, thoughts, and concerns about this problem space. March 12, 2019 at 10:29PM

Launch HN: MedCrypt (YC W19) Medical Device Cybersecurity https://ift.tt/2O1RFdW

Launch HN: MedCrypt (YC W19) Medical Device Cybersecurity Hi HN! We're Eric and Mike, founders of MedCrypt ( https://ift.tt/2u3aST7 ). Our mission is to make it easy for healthcare technology companies to build cybersecurity features into their products. I (Mike) was previously a product manager at a medical device company and witnessed an increasing concern about the security posture of Internet-enabled medical devices. This culminated in a couple of big device companies needing to issue recalls for their medical devices due to cybersecurity vulnerabilities. It struck me as an interesting transition from cybersecurity being a compliance requirement and instead a concern when managing patient safety. Being concerned about the lack of resources available to implement data security properly, or at all in some cases, we decided to build a platform that helps healthcare software and medical device companies properly integrate data security features into their products, while actively monitoring them for vulnerabilities and suspicious behavior. We address this problem by providing our customers with a configuration driven library that exposes a simple API to access data security operations, crypto library versioning/vulnerability tracking, key management, and device behavior monitoring. The features our solution provides also happen to cover all of the FDA’s new requirements for data security in medical devices ( https://ift.tt/2VQR6Gk... ). These requirements place special emphasis on proper data encryption, signature verification, intrusion detection, and vulnerability monitoring. While medical device vendors could go through the trouble of pulling together open source crypto libraries, certificate authority APIs, and monitoring solutions, or even write some of their own from scratch, we believe MedCrypt's platform offers a better alternative. We handle the complexity of integrating open source crypto libraries with PKI and monitoring infrastructure and provide simple API calls for key provisioning, certificate generation, data security ops, and monitoring. Medical device vendors use their account on the MedCrypt platform to tell us about the individual computing components that make up their device, what types of data are stored or transmitted over the wire, and what kind of security is required. This allows us to point the vendor to the appropriate MedCrypt library (C/C++ libraries or bindings for NodeJS, Java, C# .NET, etc.) to use for each component and creates a generic provisioning configuration that the MedCrypt library uses to generate the appropriate key pairs, communicate with PKI, and register CBOM metadata for vulnerability tracking purposes. Once the device and its keys are approved (via our provisioning API or predefined filters) and the certificates and signed configuration are delivered to the device, MedCrypt's library uses the certificates and the security configuration to enable simple API calls to secure the device's data. For example, after being provisioned, if a glucose monitor is required to sign each set of measurement data sent to a central system called "data-capture", the API call is boiled down to: int returnCode = glucoseMonitor.dataFor(&securedData, "data-capture", rawMeasurementData); Under the hood the MedCrypt library is using the signed data security configuration to select the cryptography resource, sign the data with the appropriate secret key, construct a data payload that encapsulates the original data and signature for delivery to the "data-capture" server, and (if enabled) registers monitoring events with regard to when and with which keys a signing operation occurred. On the other end, the "data-capture" server can verify and get access to the measurement data through an API call: int returnCode = dataCapture.dataFrom(&rawMeasurementData, "glucose-mon", secureData); Again, underneath, the library is using the configuration to establish what type of security is required for this data and whether it can trust the public key referenced by the signature on the measurement data. If the public key is trusted and the signature is verified then the original measurement data is returned to the user. The signature data can also be returned so that the integrity and provenance of the measurement data can be verified in the future. If enabled, an event is recorded indicating the status of the signature verification and from which device/keys it was generated with. The library can also be used to apply security to sockets, encrypt data at the application level, and monitor additional events, all driven by the signed configuration describing the security preferences for this device. When our monitoring service receives metadata about the security events on the device, we can then scan for anomalous behavior. Our behavior-monitoring baselines are developed using the data from multiple classes of medical devices from multiple vendors, giving our customers access to a dataset larger than they’d be able to build on their own. Medical device vendors should be able to focus on building innovative clinical features while using best of breed tools and platforms for things like security. We believe we’re building security tools in a way that optimizes data security without compromising clinical functionality. We’d be excited to hear your feedback, and how you think a healthcare-specific cybersecurity company can help medical device vendors facilitate secure connectivity.

Launch HN: AmpUp (YC W19) – A reservable electric car charging network https://ift.tt/2NZjIuy

Launch HN: AmpUp (YC W19) – A reservable electric car charging network Hi HN, This is Tom from ampUp ( https://ampup.io/ ). We're building a reservable electric car charging network out of shared private and home chargers. As a Nissan Leaf driver without a home charger, charging has been almost a daily headache for me. For many commutes and trips I have to ask myself, should I drive my Leaf, use Uber, take public transit, walk really far, or just not go? This is due to the walk-in-only model of the public charger, which results in unpredictable availability. Worse, public charging is growing at a slower rate than EV adoption, and the range estimators on EVs are no better than a 10-day weather forecast. I used the Plugshare app and it helped some, particularly the couch surfing style of charging where I arrange a 2 hour slot with some home charger hosts. When it worked well, it took out the unpredictability and therefore anxiety. However, it doesn’t always work well. Many times hosts won’t respond to text/calls to make the booking, and a couple times I forgot to bring cash/check to pay for the electricity as the host indicated. My first attempt at this problem was building a webapp that worked as an addon to Plugshare where hosts can create a calendar for their charger, and set an hourly price where drivers can pay via credit card. Once that’s set up, the host would paste the unique url to their charger’s calendar in the description section of their Plugshare listing. Long story short, this added as much inconvenience as benefit, and drivers still ended up calling the host. Given enough interests from hosts and based on experiences of a few drivers including myself, I decided to make a second attempt and just build a better app that focuses on the hosting and reservation flows. After about 2 months of hustling and grinding, we released ampUp ( https://ampup.io/ ), where users can host multiple chargers at flexible schedules and adjustable prices. Since the hosts set up sharing calendar for their chargers, the other users can make reservations with instantaneous confirmation. We use Stripe to enable peer to peer payment with credit card rather than cash/check. We know EV owners are willing to pay for charging and it’s important for hosts to be able to make a meaningful amount if we want to scale this to match our vision where one day there will always be a reservable charger near where the user is or will be. From our analysis, with a competitive (to public charger) pricing of $3/hr, hosts can expect to make $190-$270/month in profit with just 3 rented hours per day. For ampUp, our business model is to charge a flat 1 dollar to the driver per reservation. If we use the $3/hr example from earlier, a 3 hour session will cost a total of $10 to add about 60 miles from a residential level 2 charger. This "fuel" cost is on par with the most fuel-efficient gas car which is the Mitsubishi Mirage. These numbers are based on Bay Area electricity and gas costs. ampUp already has thousands of hosts, but many of them are listings we collected from all over the internet. The difference in the user experience with those hosts is that we have to confirm the reservation with them, as opposed to our own. This is a temporary limitation in the "do things that don't scale" spirit. Our goal is to instantly confirm reservations like Airbnb. We sincerely invite the HN community’s feedback on our idea and on the app and everything else in this space. You can reach me directly at tom@ampup.io or for info@ampup.io. You can download the app at the top of https://ampup.io/ . We hope ampUp will help more people to drive their electric vehicles as effortlessly as driving a gas car! March 11, 2019 at 10:30PM

Launch HN: Mudrex (YC W19) – Automated Trading Without Code https://ift.tt/2Hnv1va

Launch HN: Mudrex (YC W19) – Automated Trading Without Code Hello, HN! We're Rohit, Edul, Prince, Alankar and Snehil. We’re building Mudrex ( https://mudrex.com ). Mudrex helps traders automate their trading without having to code and spend a lot of time and money into building an automated trading infrastructure. Though we have started with cryptocurrency trading first the goal is to help anyone who wants to get into automated trading or investing across any asset class. We had been trading cryptocurrencies since sometime and were not able to track trading opportunities across 1000s of currency pairs for 24 hours a day and 7 days a week. We thought of automating our trades but faced challenges like not able to access historical data, building a testing framework to test our strategies on historical or live data and maintaining connections & orders on multiple exchanges. Also since it was all coded we were not able to quickly iterate on trading ideas since for simplest changes we had to dig into code and deploy new strategies to retest them. That also made it hard to having a log of all the trades, strategy changes, back-tests, papers to compare things at one place. After talking to 100s of traders we found out almost all active traders are facing the same problems so we decided to build Mudrex. At Mudrex traders can quickly build any kind of trading strategies using 150+ indicators, 50+ candlestick patterns, price or volume action. They can test their trading strategies on historical and live data to optimise and automate their trading by connecting their order only exchange API keys. Cryptocurrencies are just a start for us and we have been growing very quickly since the launch and getting feedback from more and more people every day. But there are millions of traders out there, trading manually across different asset classes just because they don't have capital and resources to build an automated trading infrastructure from scratch. We want to solve all of their problems so they can focus on building trading strategies instead of spending too much time on infrastructure issues. One of our user tried to define our goal as "Democratising algorithmic trading and investing" and we are working hard every day to get closer to that goal. For the next 2 months the platform is free to use but we will charge a $0-$100 monthly subscription fee depending on usage with a free tier available. Next on our roadmap are things like a code editor(where traders can build custom indicators using minimum coding), a market place between traders & investors and integrate equities & forex. We dream of reducing the gap around financial opportunities between the wealthiest and the rest. We just got started with a big dream and we are going to face many technical/design/operational challenges ahead of us but with the help of our user's feedback and support, we are sure we can achieve it. Looking forward to hear feedback from the HN community to continuously keep going in the right direction. March 9, 2019 at 11:32PM

Launch HN: GoLinks (YC W19) – Internal short links for teams https://ift.tt/2NPyFiF

Launch HN: GoLinks (YC W19) – Internal short links for teams Hello HN! We’re Jorge, Kevin and Sean and we’re building GoLinks ( https://www.golinks.io ). GoLinks is a platform that allows you to easily manage and share links by letting teams create a short link for any internal URL within a company. These links are easy to remember and share, so you don't have to bookmark or copy and paste them in emails. Each day we use and share hundreds of links to get our jobs done, without considering how long it takes to access and share these resources. It’s one reason why many of us leave tabs open in our browser: we don’t want to spend the 5 to 10 steps to navigate back to that important page. With GoLinks, you’ll be able to deep-link directly into any application with just a simple keyword entered into your address bar. This allows links to be conversational. For example, one employee can create the keyword “go/review” to point to the annual review page in Workday. Later in a meeting, that employee can mention, “Remember to visit go/review to fill out your annual reviews!” Now anyone in that meeting can remember and access the link “go/review”, without digging through their email or Slack. Golink systems are commonly used in many big tech companies such as Google, Linkedin, Twitter and Airbnb, built by internal tools engineers in those companies. These systems have become an integral part of the way tech companies share internal links. When we started our careers in tech, we would often visit each other for lunch at these tech companies and we began to notice the same go/links everywhere. In the hallways, cafes, break rooms, posters. fliers and TVs, there would be these keywords prefixed with “go/” that allowed employees to quickly access information on their devices. The employee could enter a shortened URL like go/food into their mobile browser, or desktop, and could access the lunch menu for that day. An easy and simple concept, but an extremely powerful method for internal communication. Although these systems are ubiquitous in large tech companies, we noticed there was nothing on the market that catered to startups, midsize, or non-tech companies. Companies usually don’t have the time or the resources to build sophisticated internal tools, so we set out to create GoLinks as a Service. The challenge was building an internal tool for companies that may not have any internal infrastructure. For example, large tech companies have infrastructure so when you connect to the company Wifi or access the VPN, you can access the internal company network. This allows users to access the “go” domain on the network, which resolves the deep link redirection. For smaller and midsize companies, employees might be 100% remote or working in a coworking space, or maybe the company never got around to setting up an intranet. We had to build a product that did not rely on assuming internal infrastructure. We were able to replicate the functionality of an internal network, and the simplicity of a short-link redirect system, by creating browser extensions for each of the popular browsers. The extension would proxy the “go” domain to our server and we authenticate and redirect the user to the correct location. Now coworkers can be on any network and any wifi, and as long as they authenticate in their current browser, we can find their company’s internal links. We are startup-friendly—anyone under 10 users can get started completely free—but our main initial focus is on enterprise clients. If you’ve ever used our GoLinks or any company's golink system, let us know how it’s changed your daily workflow. Thanks for reading. We appreciate your ideas and feedback! March 8, 2019 at 11:42PM

Launch HN: Cosmic JS (YC W19) - API-first drop-in replacement for WordPress https://ift.tt/2XK5r9t

Launch HN: Cosmic JS (YC W19) - API-first drop-in replacement for WordPress Hey HN, I'm Tony, one of the cofounders of Cosmic JS (YC W19) ( https://cosmicjs.com ). Cosmic JS is a drop-in replacement for WordPress that can power content for any website or app. We provide a web dashboard to create content and API tools and resources (REST and GraphQL) to integrate content into any new or existing project. Commonly referred to as a "Headless CMS", this eliminates the need to build and maintain your own CMS infrastructure. For a monthly fee, you use our CMS infrastructure and can focus on what really matters: building great products and user experiences. My cofounder Carson and I met at a digital agency where we built and managed WordPress websites. We noticed that lots of development time was spent building and maintaining the CMS itself, sucking time away from core application development. Plus we encountered the same CMS problems over and over: automatic updates caused sites to crash, a client would decide to install a bunch of plugins that caused the site to crash, comment spam was a never-ending battle. We began looking for a better way to manage content. This was 2014 and API services were becoming more popular (Stripe, Twilio, SendGrid etc were gaining traction in offloading non-core dev tasks), and it made sense that using an API could be a viable way to deal with content as well. So Cosmic JS was created to be the solution that we wanted to use: one click to add a new project, unlimited projects with a single login, a simple web dashboard to create content, and API tools and resources to integrate content into any new or existing website or app. No CMS infrastructure needed. After much beta testing, we eventually released to the public in 2016. We're now powering production websites and apps for hundreds of teams around the world across various use-cases. We know the market for a solution to this problem is big because WordPress, as of this posting, powers 30% of the web. That’s 75,000,000 websites (source: https://ift.tt/2A0k3Wr ). Plus the need for dynamic content extends beyond websites. Mobile, IOT and other emerging tech are increasingly requiring dynamic, easily integrated content. This is a hard problem to solve because a CMS has to satisfy the needs of both developers and content creators. We're different than other headless CMS providers because lots of effort has been made to make the CMS admin dashboard and content integration process as easy as possible for both the developer and content creator. We’ve been told “it doesn’t get much simpler”. We’re also very committed to education and community. We're the only headless CMS that comes with a community of developers built-in providing hundreds of apps, extensions, and integrations to learn best practices and teach others. You can get up and running with a variety of use-cases in just a few clicks. And we have a free plan that rewards contributors with a free personal Bucket forever. Check out some of the apps built with Cosmic JS: https://ift.tt/1KEnp4R . We're excited to be participating in Y Combinator for the W19 batch to help more teams avoid the pain of CMS infrastructure management so they can focus on building great products. We'd love to hear your feedback and learn more about your personal experiences building content-powered websites and apps! March 7, 2019 at 11:22PM

Launch HN: The Juggernaut (YC W19) – A Publication for the South Asian Diaspora https://ift.tt/2VJlnHf

Launch HN: The Juggernaut (YC W19) – A Publication for the South Asian Diaspora Hi HN! I’m Snigdha, founder of The Juggernaut ( https://ift.tt/2Tz5fur ), a subscription publication for the South Asian diaspora. We charge <$5/month for original stories on South Asia and its people. I’d love your feedback — new subscribers get a free week trial :) I’m Indian-American and grew up in New York. Being Indian wasn't cool growing up. Western media mostly focused on South Asia's poverty (Slumdog Millionaire) or stereotypes (Apu, taxi drivers). That started to change as I grew older. I saw more South Asians in the news — from those in spelling bees, which I used to participate in, to presidential candidate Kamala Harris, to tech CEOs like Sundar Pichai and Satya Nadella. I realized I didn’t know what was going on in the region or with South Asians nationally, let alone in my own city. My mom would forward me news on WhatsApp and I couldn’t talk to her about it meaningfully. I also found that journalism was becoming targeted: The Athletic for Sports, The Infatuation for food, Blavity for black millennials. And I noticed that as China grew, publications started China sections and readers loved Bill Bishop’s Sinocism, a newsletter with sharp China analysis. But there was no national, inclusive, well-reported publication for South Asians, the fastest growing demographic in the US and the largest diaspora in the world. So, every weekend, I’d write a email newsletter ( https://www.inkmango.com ) linking to the best articles on South Asia(ns) with my thoughts on a pressing issue, from the Harvard affirmative action lawsuit to South Asian representation in Crazy Rich Asians. The newsletter grew to the thousands. After doing this for a few months, I realized linking to other publications wasn't enough. I was craving coverage I wasn't seeing. That’s why I decided to figure out what it would take to start a new publication with our own reported stories. We called it The Juggernaut. We are starting with one new story a weekday. Our stories have included profiles on South Asian founders, an interview with comedian Hari Kondabolu, an essay on the erasure of Freddie Mercury's brownness, and an exploration of the rise of the Subtle Curry Traits Facebook group. Media is difficult. People like free content. We launched behind a paywall because it allows us to pay journalists well and quickly, and invest in better journalism. And paid doesn’t mean exorbitant. I’d love to know — what publications do you read and why? What makes you want to pay for something? What pitfalls should we watch out for? Happy to answer any questions/comments; you can also email me at snigdha@thejuggernaut.com. March 6, 2019 at 10:42PM

Launch HN: Dockup (YC W19) – On demand staging environments for dev teams https://ift.tt/2EPD9Da

Launch HN: Dockup (YC W19) – On demand staging environments for dev teams We're Emil and Yuva, co-founders of Dockup ( https://getdockup.com ). Dockup spins up on-demand environments so engineering teams can quickly test their code changes. When you open pull requests, Dockup creates disposable environments automatically and delivers URLs to your chatrooms; engineers don't have to wait their turn to manually deploy to a staging server for testing their code changes. Anyone in the team can then click on these URLs and preview features before merging pull requests. Because each environment has all the services in the tech stack, it lets you catch bugs which usually happen only in production. My co-founder and I were colleagues at our previous job (for ~6 years) where we worked as consultants, mostly working on Rails, React and Elixir projects and had the luck to work closely with many engineering teams. We often saw that teams would slowly lose confidence in their code as their codebases and team sizes grew and code changes would take longer to ship. At a payments company that we worked for, things often worked fine in dev but broke in production and eventually they started having company wide meetings before teams could deploy anything to production. Wanting to help developers ship faster and with more confidence, and also to scratch the itch of writing something in Elixir, we started building a tool as a hobby project, which eventually turned into our product. Honestly, at first I thought that if we could build it, anyone else could build it internally too and no company would pay money for this, until we actually started talking to companies which have done it. We learned that it usually takes a few months for a developer to build an internal tool that automates PR review deployments. Most engineers told us they don't like having to support this set up and keep it running after they've built it and moved on to solving other problems. We faced many problems on the way, for example - the need for pre-seeded prod like databases for testing features, being able to support architectural changes (for example, adding a message queue in the tech stack and testing it with Dockup) etc. We have now reached a place where we are able to onboard most of our customers without having to build custom features each time. We are excited to share what we have built with all of you! We are sure the HN community will have many knowledgeable engineers who have tried solving this problem and we're looking forward to hearing your thoughts. If you want to try Dockup now, you can do it by running the Dockup agent on your servers. If you don't want to run your own servers, you can request access for the managed Dockup cluster by going to our pricing page and we'll roll out access in a couple of days. Pricing starts at $75 for small teams. Thank you for reading! March 5, 2019 at 11:34PM

Launch HN: Saratoga Energy (YC W19) Better Carbon Nanotubes from Carbon Dioxide https://ift.tt/2XDCHPF

Launch HN: Saratoga Energy (YC W19) Better Carbon Nanotubes from Carbon Dioxide Hi HN, I’m Drew, founder of Saratoga Energy ( https://ift.tt/2Tce0v7 ). We make better carbon nanotubes at one-fifth the price. Carbon nanotubes are a form of nano-scale carbon fibers (5,000X thinner than human hair) with remarkably high strength, electrical conductivity, and thermal conductivity properties. This makes them useful in a variety of commercial applications. Lithium-ion batteries designed for electric cars already use carbon nanotubes to reduce heat generation during charging and to improve electrical conductivity. This results in faster charging and improved battery life. However, the cost is so high ($300/kg) that battery manufacturers are forced to use the minimal amount, rather the optimal amount. Our breakthrough in manufacturing cost enables battery manufacturers to use the optimal amount, allowing electric cars to safely recharge in 10 minutes or less. This could give electric cars the boost they need to replace gasoline engines. The idea to start the company grew from an idea posed to me by my Dad back in 2012 - is there a way to transform carbon dioxide, a greenhouse gas, into something valuable? I thought this would be an exciting challenge because most carbon dioxide technologies at the time were focused on storing it in underground caverns or converting it into commodity chemicals where it would be difficult to profit without substantial government subsidies. After reading an article about Tesla’s intentions to only source raw materials that were sustainably produced in North America, we settled on developing a low-cost electrochemical process to convert carbon dioxide into graphite. Graphite is an essential energy storage material used in lithium-ion batteries. After deciding on the product, my Dad and I put together a small team of chemical engineers to help with the patents and applications for grants from the Department of Energy and the National Science Foundation. When we received our funding, we began work with Lawrence Berkeley National Laboratory to construct small batteries to test the material we had made. We noticed that some cells would charge three, or sometimes five times faster than commercial reference materials. So we pulled the cells apart to have a look at the graphite with a high-powered microscope. All of the fast-charging graphite was matted with tiny hairs (I later learned that it sounds cooler if you call them “carbon nanotubes”). We thought about it for a few days and did some research. We eventually figured out that certain metals we had tested in our production process were likely responsible for the growth of carbon nanotubes. So we isolated those metals to test the theory. It worked! Now we had a process that could either grow carbon nanotubes or graphite - both at an estimated cost under $5/kg. The difference being that the market price for battery-grade graphite is $10/kg and the market price for battery-grade carbon nanotubes is $300/kg. If the price of graphite is reduced from $10/kg to $5/kg, electric cars get a bit less expensive and the market expands a bit more. If the price of carbon nanotubes is reduced from $300/kg to $5/kg, electric cars cold potentially charge in about the same amount of time it takes to refill a tank of gas, which could create exponential growth in the electric car market. We discussed this with our grant manager and agreed that it made sense to pivot and scale up the carbon nanotube process - which leaves us here today in W19. What’s different about our technology is that we produce carbon nanotubes through the electrolysis of molten carbonate salts. The electrochemical reaction produces carbon (nanotubes), oxygen gas, and metal oxides, which are further reacted with carbon dioxide to re-generate the carbonate salt starting material. So the net reaction is the input of energy to drive the conversion of carbon dioxide to carbon nanotubes and oxygen. Industry has been using chemical vapor deposition to make carbon nanotubes since they were first discovered in 1991. We believe that our platform is better for a few reasons: 1) electrochemistry is tunable and this gives us control over the size and shape of the nanotubes, so they can be custom-tailored for specific battery chemistries and applications outside of energy storage as well; 2) the energy requirement for our manufacturing process is estimated to be 27 kWh/kg, five times less energy intensive than chemical vapor deposition; and 3) our technology represents a value-added use for carbon dioxide, and if powered by electricity from renewable sources, would have a negative carbon footprint. I think the reason nobody has commercialized this production method yet, or come up with some other high-efficiency process, is because chemical vapor deposition is relatively simple to operate and relatively simple to scale. Billions of dollars worth of chemical vapor deposition infrastructure are already established, and historically, there haven’t been many new market opportunities that would justify investing in new technologies to drive down cost. Only recently have researchers demonstrated the potential for carbon nanotubes to improve the performance of new applications like advanced energy storage, high-strength carbon fibers and composites, lightweight electrical wiring, and concrete composites for roads that don’t crack. If carbon nanotubes were less expensive, these new applications could be worth billions while also creating sizable reductions in greenhouse gas emissions. It is our mission to bring new markets like these to life and to develop new products that best take advantage of what our carbon nanotubes have to offer. I believe that we are best positioned to break this cost-curve and bring this technology to market because molten carbonate electrochemistry is not a well-known science. What we’ve learned since our foundation in 2012 is not commonly taught in universities. Our knowledge was acquired through hands-on experience and in-house development of intellectual property. Hopefully some of you folks are also interested in carbon nanotubes, or at least share a mutual dislike for carbon dioxide. I’m looking forward to sharing some ideas with everyone! -Drew March 4, 2019 at 11:23PM
