  • Mobot
    Mobot (w2019)Active • 40 employees • New York, NY, USA
    Mobot (YC W19) is a QA-as-a-service platform using actual mechanical robots to automate testing of repetitive functions on real mobile devices. Mobot's human-supervised robots make it possible to automate mobile app tests that emulators, virtual devices, and existing frameworks can't. This approach eliminates thousands of hours of manual testing, increases testing efficiency and physical device coverage, and captures more bugs in-app before app store launches than software can do alone.

  • Avenue
    Avenue (w2021)Active • 8 employees • New York, NY, USA
    Avenue is a simple way for business teams to set up alerts from their database or data warehouse. Think Datadog / PagerDuty for operations teams. Operations teams create set-and-forget alerts on all their data, so they can be more proactive with their time (and monitor on more nuanced triggers than just what fits on their dashboard page). Avenue can improve response times to critical problems from several days to real-time by alerting directly on the data sources that customers already use.

  • Anima App
    Anima App (s2018)Active • 20 employees • New York, NY, USA
    Anima is converting design to code, automatically. Why does the world need Anima? Taking user-interface design to production is hard. Automated design-to-code will change the way we build software. The future of Front-end With Anima, designers can translate design to code in a single click. - Need a website? Designers can create one directly from their design tool. Figma, Adobe XD, or Sketch. - Need to go from a prototype to a PoC asap? No coding required here as well. - For engineers, it's a coding assistant, keeping developers in control. Less grunt work, pushing-pixels, and design that is lost in translation.

Under the hood, Porter manages the same kind of infrastructure that growth-stage companies use and allows you to scale without DevOps overhead.

  • Decent
    Decent (w2022)Active • 8 employees • New York, NY, USA
    Decent's core product,[The Box](https://decent.xyz/), enables 1-click transactions using any token across chains. For example, a user can purchase an Optimism NFT off primary or secondary sales using USDC on Arbitrum. As applications splinter across an increasing number of rollups and app chains, wallets and dapps will have to meet users at their point of liquidity vs. expecting users to jump through hoops to arrive with tokens on the correct network.

  • Blockscope
    Blockscope (s2022)Active • 4 employees • New York, NY, USA
    Blockscope is a Web3 data platform that enables anyone interested in on-chain data to quickly spin up live or historical data pipelines (for blocks, event, transaction, wallets, token, NFTs, etc). Similar to AWS, users have access to variety of managed software services to analyze, interact with or inject captured data into their apps. Our platform is built around the core idea of off-loading the on-chain data that our customers need for their Web3 apps, and reliably storing them for quick access/use. We offer products on top of the core data we index for our customers. Some of these services are contract analytics, wallet profiling, events & transactions database as a service, push notifications, webhooks, and developer tools. Our mission is to enable everyone to easily access and consume on-chain data!

  • Optic
    Optic (s2018)Acquired • 5 employees • New York, NY, USA
    We help developers collaborate at scale and build better APIs. Optic’s open source tools makes it easy for developers to document API changes, review each other’s API changes during code review, and catch breaking changes before they reach production. **tl;dr** It’s version control but for behavior not code. We are taking the really successful ideas from Git / Code Review / CI and applying them to API descriptions and (future) other non-code artifacts. Engineers at [Snyk](https://snyk.io/) use Optic daily to make the new Snyk API great.
