Overview
ReadMe is an interactive API documentation platform founded by Gregory Koberger, with company origins in 2014 and a public launch through Y Combinator's Winter 2015 batch. Headquartered in San Francisco, California, the company has raised roughly $10 million in funding, including a 2019 Series A led by Accel, and employs an estimated 70 to 83 people.
The platform is used by more than 4,000 companies, ranging from startups to large enterprises such as Microsoft and Akamai, to turn static API docs into interactive, testable reference hubs.
Key Features
ReadMe's core differentiator is letting developers execute live API calls and see real responses directly inside the documentation, rather than switching to a separate API client or Postman collection. Built-in analytics show which endpoints get tested, where developers get stuck, and which sections drive the most engagement.
Higher tiers add collaboration features like branching and review workflows, private documentation, custom MDX and CSS support, changelog and forum modules, and a growing suite of AI tools including an AI writing agent, AI linter and documentation audits.
Pricing
ReadMe offers a free Starter plan with the core interactive reference and basic AI features, a Pro plan at $250 per month billed annually that unlocks team collaboration and expanded AI tooling, and an Enterprise plan starting at $3,000 or more per month on annual contracts with SSO, audit logs and dedicated support.
An Ask AI add-on is available across all tiers for an additional $150 per month for teams that want the platform's fuller AI-assistant capabilities without moving to a higher plan.
