Launch HN: Airbyte (YC W20) – Open-Source ELT (Fivetran/Stitch Alternative) https://bit.ly/3t1fQwS

Launch HN: Airbyte (YC W20) – Open-Source ELT (Fivetran/Stitch Alternative) Hi HN! Michel here with John, Shrif, Jared, Charles, and Chris. We are building an open-source ELT platform that replicates data from any applications, APIs, databases, etc. into your data warehouses, data lakes or databases: https://bit.ly/3ooW2A1 . I’ve been in data engineering for 11 years. Before Airbyte, I was the head of integrations at Liveramp, where we built and scaled over 1,000 data ingestion connectors to replicate 100TB worth of data every day. John, on the other end, has already built 3 startups with 2 exits. His latest one didn’t work out, though. He spent almost a year building ETL pipelines for an engineering management platform, but he eventually ran out of money before reaching product-market fit. By late 2019, we had known each other for 7 years, and always wanted to work together. When John’s third startup shut down, it was finally the right timing for both of us. And we knew which problem we wanted to address: data integration, and ELT more specifically. We started interviewing Fivetran, Stitchdata, and Matillion’s customers, in order to see if the existing solutions were solving their problems. We learned they all fell short, and always with the same patterns. Some limitations we identified are due to the fact that they are closed source. This prevents them from addressing the long tail of integrations because they will always have a ROI consideration when building and maintaining new connectors. A good example is Fivetran which, after 8 years, offers around 150 connectors. This is not a lot when you look at the number of existing tools out there (more than 10,000). In fact, all their customers that we talked to are building and maintaining their own connectors (along with orchestration, scheduling, monitoring, etc.) in-house, as the connectors they needed were either not supported in the way they needed or not supported at all. Some of those customers also tried to leverage existing open-source solutions, but the quality of the existing connectors is inconsistent, as many haven't been updated in years. Plus, they are not usable out of the box. That’s when we knew we wanted Airbyte to be open-source (MIT license), usable out of the box, and cover the long tail of integrations. By making it trivial to build new connectors on Airbyte in any language (they run as Docker containers), we hope the community will help us build and maintain the long tail of connectors. While open-source also enables us to address all use cases (including internal DBs and APIs), it also allows us to solve the problem inherent to cloud-based solutions: the security and privacy of your data. Companies don’t need to trust yet another 3rd-party vendor. Because it is self-hosted, it will disrupt the pricing of existing solutions. Here’s a 2-minute demo video if you want to check out how it looks: https://www.youtube.com/watch?v=sKDviQrOAbU Airbyte can run on a single node without any external infrastructure. We also integrate with Kubernetes (alpha), and will soon integrate with Airflow so you can run replication tasks across your cluster. Today, our early version supports about 41 sources and 6 destinations ( https://bit.ly/2KVIzCo ). We’re releasing new connectors ( https://bit.ly/3olkEtI ) every week (6 of them have already been contributed by the community). We bootstrapped some connectors using the highest-quality ones from Singer. Our connectors will always remain open-source. Our goal is to solve data integration for as many companies as possible, and the success of Airbyte is predicated on the open-source project becoming loved and ubiquitous. For this reason, we will focus the entirety of 2021 strengthening the open-source edition; we are dedicated to making it amazing for all users. We will eventually create a paid edition (open core model) with enterprise-level features (support, SLA, hosting and management, privacy compliance, role and access management, SSO, etc.) to address the needs of our most demanding users. Give it a spin: https://bit.ly/3iMzMPD & https://bit.ly/3akX7UT . Let us know what you think. This is our first time building an open-source technology, so we know we have a lot to learn!

Launch HN: Aviron (YC W21) – High-Intensity Peloton for Rowing https://bit.ly/2M0LvxS

Launch HN: Aviron (YC W21) – High-Intensity Peloton for Rowing Hey HN! I’m Andy, founder of Aviron ( https://bit.ly/2YcWRRX ). We make a high-intensity version of Peloton for rowing, with competitive games, live races and strength programs. Our content puts a focus on HIIT (high intensity interval training) due to its physical and cognitive benefits. I feel like sometimes this pisses the hardcore rowers off but I’m not a rower, I’m a tech guy. I also think fitness is important and have been working out all of my adult life. Before Aviron, I worked full time and long hours so I did a lot of my thinking during late night gym sessions. Like many people I avoided the rower because not only did I not enjoy cardio but damn that machine was hard and boring. There was a moment at some point in 2016 when I realized I could do something with this. The connected fitness market in the US at that time was small but growing rapidly. Aviron is a rowing machine because it’s the most efficient and effective workout you can have in a short amount of time on one machine. The rowing motion is low impact, engages 85% of muscles, is very difficult and as a result can also be boring. This makes the rowing machine an ideal ‘candidate’ to pair with the gaming-inspired, competitive content I began to envision in 2016. The research was telling me there was a definite potential market niche I could fill but what I didn't know was that no manufacturer would speak to me. I probably called and emailed 50 manufacturers. I eventually kickstarted a few conversations and finally a relationship, by flying to Taiwan, connecting with a local who could translate, and knocking on doors in person. It sounds reasonable in hindsight but the process to finalizing a production contract start to finish took me a full year. A year of trying to understand the manufacturing landscape, developing relationships and convincing potential suppliers that I would eventually be worth their time. Ultimately my key takeaway is that Taiwanese manufacturing relationships are just that - relationships. Manufacturers are looking for long-term trusting partnerships and they are much less motivated by money than my initial assumption. I’m reminded of this constantly - this month alone I have received emails re: product delays twice - and I stupidly tried to throw money at the problem, in the process offending the Taiwan team by implying they would work harder if money was on the table. Finding and building a solid relationship with a production partner was challenging but I would give it a 7/10 relative to the hurdles that came later. The manufacturer had no experience or interest in getting the machine to work along with our custom android touchscreen. As much as I see myself as a “tech guy”, I don’t have an engineering degree. My dad does and so does my brother but I went the business degree route. Long story short, figuring out the details of making these two pieces work together was a nightmare. Again, in hindsight, it’s kind of cool - I understand my machine inside and out; I’m confident I could take it apart down to the screws and put it back together. I can also work comfortably with an oscilloscope and understand how most of the components work on a typical fitness equipment circuit board - there was a lot of circuit board soldering trial and error at one point. I knew that I was taking on a lot with a software and hardware venture but what nobody tells you is how many miles you’re going to drive and fly when you’re taking on hardware. During our slow tip-toe pivot from B2B to B2C sales, we discovered home customers would find 10x the problems a gym would. There was a week in 2019 I drove to a customer’s home 6 hours away multiple times a week for nearly a month. Each trip I thought we had found the solution; the ride back was crushing. This was one of many problems we faced. I’m happy to be able to say the bugs are mostly worked out! Our customers navigate a 22” touchscreen to browse 250ish content options - like my favorite and the first game we ever developed - Last Hope, an end-of-the-world inspired game where you’re being chased by zombies. As your row to escape the Ai will benchmark your fitness output and adjust the zombies’ speed to maintain a challenging pace for your fitness level. The content for Aviron was developed with strength training and High Intensity Interval Training (HIIT) in mind. For example, one of our 6 workouts categories is “Pros vs. Joes”, a program that allows you to compete against pre-recorded Olympians and professional athletes in a race. Our customers are fitness enthusiasts who don’t enjoy long cardio workouts and crave the competitive and challenging pace of activities like CrossFit and F45, at home - especially throughout Covid. HIIT workouts tend to be shorter, have been proven to improve cognitive ability and help slow the aging process via preservation of DNA. To me, the dual cognitive and physical benefits were really key. I began to work out in my teens, physically I felt better and my self esteem improved. Cognitively, I went from dealing with undiagnosed ADHD and struggling my way through school to slowly noticing an improvement. People told me I was “growing out of” ADHD - which is probably partially true - but something clicked when I was researching fitness programming for Aviron. Learning about HIIT and it’s (data proven) benefits, I started to realize that my commitment to consistent and challenging physical fitness had likely paid a large part in my “growing out it” as well. Currently, we have bootstrapped Aviron to a good place; we’ve sold nearly a thousand rowers to gyms, hotels, schools and even Nike headquarters as well as homes. Or churn rate is <1% and our customers are telling us they’re happy. And they’re paying their membership every month so we believe them. :) We are continually working on Aviron to improve the software, content and customer experience so if you have a chance please check us out and let me know what you think. I’m excited to hear from the community. I’ll be hanging out in the comments all day. January 25, 2021 at 05:53PM

Show HN: Retrospective on having my “Show HN” on the front-page https://bit.ly/3qOq5Tx

Show HN: Retrospective on having my “Show HN” on the front-page I was lucky enough to have my site trending on Friday (https://bit.ly/39QJv3g). It’s an icon site that lists open source icons. I wanted to share some stats on the results after 3 days. Worth noting was that I submitted it on a Friday morning (at which point I went for a walk and a coffee; eek). - 24,997 page views. I (embarrassingly) didn’t have GA set up when I first submitted it, so this is probably missing a few hundred page views - 21 “feedback” emails (half of which were spam). I assume such a high percentage of these were spam because my Feedback form didn’t require email addresses. - 5 note-worthy emails from people which may result in some sort of collaboration - 10 mailing list subscriber sign ups. Running through MailChimp, and it’s not emphasized at all (eg. just a link in the footer). Purposefully not email-gating people to download, since I want this to be a very developer-centric site, and it feels a bit unsettling to email-gate other people’s digital content. - 2,670 icon downloads - 74 comments. A big caveat to this one: I replied to almost every comment. The thinking is that if someone took the time to comment (even just a “thanks”), I wanted to take the time to reply to them as well. Also, I purposefully didn’t reply to people who were commenting on their own alternative services. Perhaps a tad uncouth, but I didn’t want to shine a light on a comment that was designed to detract from my submission. I would have made an exception if there was substance to those comments beyond the detraction. - One founder from a related (and leading) service (Flaticon) jumping into the comments. I really appreciated this. Similar to how Patrick Collison (of Stripe) is often seen replying to comments on Stripe-related posts. This founder submitted thoughtful replies to people’s criticisms, which I thought was quite considerate. January 25, 2021 at 04:09PM
