How a one-person side project with an owl mascot became the documentation layer for NVIDIA, Amazon, and thousands of other API companies - and why it stayed profitable while barely raising money.

The documentation platform that started as an open-source tool for developers now wants to keep the world's product docs honest - for humans and the AI agents reading over their shoulder.
Sagar Batchu
Sagar Batchu is the co-founder and CEO of Speakeasy, a San Francisco developer-tools company that turns OpenAPI specs into production-grade SDKs, Terraform providers, and MCP servers. A computational physicist by training who spent a decade building data infrastructure - including scaling LiveRamp's London engineering office from zero to 50+ engineers - he started Speakeasy in 2022 with Simon Yu to fix the unglamorous, error-prone work of shipping and consuming APIs. The company has raised roughly $29 million, including a $15 million Series A led by FPV Ventures, and counts Vercel, Mistral AI, and Verizon among its users.
Speakeasy
Speakeasy is a San Francisco developer-infrastructure company that turns an OpenAPI specification into production-grade, type-safe SDKs across ten-plus languages, then keeps them in sync automatically as the API changes. Founded in 2022 by Sagar Batchu and Simon Yu, it has expanded from SDK and Terraform-provider generation into an AI control plane for the Model Context Protocol - products like Gram and the MCP Gateway let companies expose their APIs as governed tools for AI agents. Speakeasy has raised roughly $26 million, including a $15M Series A led by FPV Ventures in 2024, and counts Vercel, Mistral AI, Clerk, Kong, Fivetran, Airbyte, and SolarWinds among its customers.
