Firecrawl Raises $75M Series B: Alexandria for AI Agents

Firecrawl closed a $75M Series B led by Smash Capital to launch Alexandria—a unified knowledge library for AI agents.

What it is:
Alexandria connects official data providers, custom connectors, and Firecrawl's own indexes (research, developer, government) so AI agents find, understand, and pull from any source in one API call.

The metrics:
• 1.5M users already building with Firecrawl
• 21% higher answer quality vs. built-in web tools (blind testing, 845 tasks)
• Pays data providers (Wikimedia Enterprise first)
• Covers tens of millions of scientific papers, code repos, laws

How it happened:
→ Founders built Mendable (AI chat for docs), hit bottleneck: web data extraction
→ Spun out Firecrawl; 1.5M devs adopted it in 2 years
→ Users' AI agents needed broader coverage
→ Raised $75M to build Alexandria: one API for all knowledge

Why it matters:
AI agents can't reason over data they never find. Alexandria removes the integration tax. For founders building AI products, this is table stakes.
