Crunchbase
The definitive B2B database for company and investment research.
Harmonic
Startup discovery API and MCP for company intelligence, founder research, and deal sourcing.
API & MCP Analysis
For AI-native operators choosing between Crunchbase and Harmonic, the decision comes down to API accessibility and how easily your agent can interface with each tool.
Harmonic has the edge here with an official MCP server, letting you connect it directly to Claude or Cursor. Crunchbase requires a REST API integration, which means your agent needs the API docs to build the connection.
"Claude, use the Crunchbase API to find all AI startups in Europe that raised a Series A in the last 30 days."
"Claude, use Harmonic to find startups in the AI infrastructure space founded by engineers from Google and Meta with less than $100M in total funding."
