Speakeasy

Generates type-safe SDKs and MCP servers directly from OpenAPI specs, turning any REST API into client libraries and AI agent tools.

Speakeasy was founded in 2022 by Sagar Batchu and Simon Yu, who had both worked on API platforms and internal developer tools before starting the company to fix a problem most API teams solve badly: hand-maintaining SDKs in half a dozen languages every time an endpoint changes. Speakeasy generates idiomatic, type-safe client SDKs directly from an OpenAPI specification, and regenerates them automatically in CI whenever the spec changes, so the SDK and the API can't silently drift apart. The company raised a $15 million Series A led by FPV Ventures, with Google Ventures and Quiet Capital also participating, on top of earlier seed funding. As API consumers shifted from humans reading docs to AI agents calling tools, Speakeasy extended the same OpenAPI-to-code pipeline to generate Model Context Protocol (MCP) servers, letting a documented API become a set of tools an LLM agent can call without a team writing that integration layer by hand. Speakeasy is based in San Francisco and collaborates with maintainers of projects like Zod and Pydantic on its schema tooling.
