Buildwithfern
New York, NY

Overview

At Fern, we believe every software company should offer a world-class API. We're building the toolkit to make that possible. We enable customers like Square, ElevenLabs, Webflow, and Intercom to offer a best-in-class developer (DX) and agent experiences (AX).

Our team is primarily ex-Palantir and ex-founders, working together from our office in Williamsburg, Brooklyn. We give builders the autonomy to take ownership, the speed to move quickly, and the support to do the best work of their careers. Fern is growing more than 4x year-over-year, is at the Series A stage, and has raised over $10M from Bessemer and Y Combinator.

We value in-person collaboration and work out of our office in the Williamsburg neighborhood of Brooklyn.
