About
Nango is a San Francisco-based integration infrastructure platform — backed by Y Combinator (W23) with $1.2 million in annual revenue in 2024 — providing developers and engineering teams with a unified API platform that abstracts the complexity of building, maintaining, and scaling product integrations, offering 400+ pre-built API connectors, 600+ ready-to-use integration templates, and a custom integrations-as-code framework that handles OAuth, rate limiting, pagination, error handling, and data normalization across every third-party API a product connects to. Founded in 2022 and operating with an 8-person team, Nango replaces the custom integration code that engineering teams write and maintain for every API connection their product requires.

About
Stably AI is a San Francisco-based AI test automation platform — backed by Y Combinator — reaching $1 million in annual revenue in December 2024 with a 5-person team — providing engineering teams with an AI platform that auto-generates, runs, and maintains end-to-end tests in CI/CD pipelines with zero-flakiness guarantees and self-healing capabilities that automatically repair tests when UIs change, replacing the brittle Playwright and Cypress test suites that break with every UI update. Founded in 2023 by ex-Google Chrome infrastructure engineer Jinjing Liang (CEO) and ex-Uber Safety ML engineer Neil Parker (CTO), Stably enables customers like OpenArt (which scaled to $16M ARR with a 10-person engineering team using Stably) to achieve test coverage without dedicated QA engineers.
