About Crunchbase MCP Server
What you can do
Connect AI agents to the Crunchbase API for complete business intelligence and startup ecosystem analysis:
LlamaIndex was built to ground AI in data. When you connect Crunchbase through Vinkius, 10 tools combine with indexed documents, vector stores, and SQL databases in a single query turn. The agent does not choose between historical knowledge and live operations. It uses both. Ask a question that requires last quarter's report and today's API response, and LlamaIndex delivers a single, comprehensive, grounded answer. This is the architecture for hybrid intelligence: indexed depth meets operational breadth.
- Search companies by name to find startups, enterprises, and emerging tech firms
- Get complete company profiles with founding dates, headquarters, employee counts, and operating status
- Track funding rounds from Seed to Series D+ with amounts, dates, and investor syndicates
