Firecrawl, a web data infrastructure company, has completed a $75 million Series B led by Smash Capital and launched Alexandria, a knowledge base designed for AI agents. The platform is intended to provide unified access to the live web, official data providers and specialized indexes. According to Firecrawl's official page, Alexandria currently integrates 82 data providers and 471 data capabilities, covering more than 113 million papers, README files, issues and technical documents across 28 categories, including finance, government, code, shopping and real estate. It can be accessed through MCP, CLI and API interfaces. Firecrawl said internal testing found Alexandria's answers were 21% better than those from built-in web tools on about 1,000 directory-style questions.
