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 50k+ 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” applications. We sold to companies like MongoDB, Coinbase, Snapchat, and more. To do this, we spent a surprising amount of time building reliable infrastructure for getting clean data from the web. When we started to see our founding friends rebuilding the same thing, we thought we might be on to something.
Why Firecrawl
- Technical ownership – Lead critical browser technology and infrastructure
- Real impact – Directly shape how our browser stack drives our entire product
- High velocity – Rapid iteration and deployment of your work
- Small team, big ambition – Collaborate closely with founders, influencing key decisions and future directions
