## Summary

Largest API marketplace with 4M developers and thousands of API providers; unified discovery, testing, and management for public and enterprise internal APIs.

## Company Overview

RapidAPI is the world's largest API marketplace and developer hub, providing a platform where developers discover, connect to, and manage thousands of public and private APIs through a unified interface. Founded in 2015 and headquartered in San Francisco, RapidAPI connects over 4 million developers with APIs from thousands of providers — weather data, financial data, social media, translation, geolocation, and every category of web service — through a single authentication layer and consistent SDK.

The company raised $150 million in Series D funding in 2021 at a $1 billion valuation, backed by SoftBank, Andreessen Horowitz, and others. RapidAPI's marketplace model benefits from network effects: more API providers attract more developers, and more developers attract more API providers. The company also provides RapidAPI Enterprise Hub, a white-label internal API marketplace for large organizations to catalog and govern their internal and partner APIs across engineering teams.

In 2025, RapidAPI has expanded beyond API discovery into API testing, monitoring, and governance through its acquisition of Paw (the API testing tool for Mac) and integrations with CI/CD pipelines. The company serves developers across startups, enterprises, and individual builders who need to integrate third-party APIs into their applications. As AI applications increasingly depend on external APIs for data and capabilities, RapidAPI's directory of AI model APIs, data providers, and utility services positions it as an important discovery layer. The company competes with Postman (API development platform), Apigee (Google), and Kong in different aspects of the API lifecycle.
