Engineering, Product and Design Startups funded by Y Combinator (YC) in New York 2025

Brainboard is a collaborative and end-to-end solution for engineers to visually design & manage their Cloud infrastructures. We allow companies to lower the learning curve while moving to IaC, build a self serve model, have a service catalog to not reinvent the wheel. Both technical profiles with 25+ years of combined expertise and after working together at a major French Cloud provider, Chafik and Jeremy launched Brainboard in 2020.

Infield helps software teams keep their open source dependencies up to date. We’re automating away the toilsome work of reading changelogs, assessing risk, and upgrading packages so that software teams can focus on shipping features. We’re a small team of repeat founders passionate about making open source easier to use.

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.

Alloy is an integration platform used by Amazon, Gorgias, Postscript, & others to launch ERP, commerce, CRM, and various other integrations. Founded in 2019, the company is backed by $27M from a16z, Bain Capital Ventures, Y Combinator, and others.

We are building a cloud platform to help companies deploy and scale AI applications.

Fastgen is a low-code API and workflow builder with an integrated Postgres DB. Our drag-and-drop platform allows you to rapidly develop custom APIs and workflows with ease. Our integrated Postgres DB makes it even easier to create, read, update, and delete data in your applications.

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.

Trained on your unique style, Aesthetic generates high-quality visuals that match your aesthetic in seconds.

Nextmv is a DecisionOps platform that accelerates optimization AI teams with tools for deployment, testing, CI/CD, collaboration, and management of decision models. With Nextmv, developers can create scalable, custom decision services complete with unique API endpoints and options to integrate with popular solvers and modeling solutions.

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.

CodeStream's IDE plugins take the pain out of code reviews. With one command, request feedback on a snapshot of your repo, including uncommitted & unpushed code, allowing you to verify that your work-in-progress is on the right track. (You can also do it the old-fashioned way by committing & pushing at the end of your dev sprint, of course)

Weav is building the digital infrastructure to connect small businesses with financial institutions.

Bracket is the two-way data pipeline between popular business tools and backend databases. When ops teams update data in Salesforce or Airtable, and engineers update data in the database, Bracket connects the two sources to reflect the same information.

Yhat (YC W15, pronounced y-hat) was an end-to-end data science platform. Acquired by Alteryx (NYSE:AYX)

Reflect is a no-code tool for automated website testing. Instead of building and maintaining complex Selenium tests, companies use Reflect to run automated end-to-end tests without writing code.
