About Firecrawl

Firecrawl is the easiest way to extract data from the web. Developers use us to reliably convert URLs into LLM-ready markdown or structured data with a single API call. In just a year, we’ve hit millions in ARR and 70k+ GitHub stars by building the fastest way for developers to get LLM-ready data.

Previously, we built Mendable, one of the first commercially available “chat with your data” tools. To support customers like MongoDB, Coinbase, Snapchat, and more, we built reliable infrastructure for getting clean web data. When we noticed our friends building the same internal tooling, Firecrawl was born.

We’re a small, fast-moving, technical team building essential infrastructure for the AI era. We value autonomy, clarity, and shipping fast.
