Fern

Fern helps software companies build a world-class API experience. Our customers include industry leaders like Nvidia and Square, as well as fast-growing AI companies like ElevenLabs and OpenRouter.

Founded in 2022, we’re less than 20 people, building open source, and backed by Bessemer and YC. Our customers include Square, Auth0, Intuit, Cohere, ElevenLabs, and Webflow. Our team is small and talent-dense. We’re a team of builders from Google, Palantir, Amazon, and Uber, working together in Williamsburg, Brooklyn. We were acquired by Postman — giving us access to 40 million users and 98% of the Fortune 500 — while maintaining the independence, speed, and ownership of a startup.
