Coresignal Fundable
Pros
  • + Massive scale — 3B+ records across companies, employees, and jobs with regular freshness updates
  • + Official MCP server for direct LLM/agent integration with multi-source company, employee, and jobs APIs
  • + Clean REST API with simple API key auth, Elasticsearch DSL support for complex queries, and bulk collect endpoints
  • + First-class AI agent support — offers MCP server, natural language semantic search, and deal alerts that map well to agentic workflows
  • + Rich structured data (50+ datapoints per startup, 400K people, 60K investors) returned as JSON — ideal for LLM function calling and downstream processing
  • + Surfaces new VC deals before competitors and provides sourced datapoints, giving agents access to timely, verifiable funding intelligence
Cons
  • - No free ongoing tier — free trial is 14 days only, paid plans start at $49/mo with limited credits
  • - Raw data may require preprocessing (duplicates, HTML artifacts, inconsistent formatting from web-scraped sources)
  • - Full API access requires Enterprise plan with custom pricing — Pro/Pro+ tiers are export-limited and may not cover programmatic agent usage at scale
  • - No public OpenAPI spec, so agents cannot auto-discover endpoints or generate typed clients without manual setup
