Pricing Comparison

Which YC Startup Data API Should You Choose?

For YC-Specific Intelligence

Recommendation: Netrows — The only API with dedicated YC endpoints that let you search 5,700+ companies by batch, industry, status, region, and hiring activity. Get founder profiles, open jobs, and launches at 1 credit per call.

For Multi-Platform Startup Research

Recommendation: Netrows — Combine YC company data with LinkedIn profiles, GitHub activity, X (Twitter) presence, and more in one API for comprehensive startup intelligence pipelines.

For Broad Startup Ecosystem Data

Recommendation: Crunchbase — If you need funding rounds, investor profiles, and acquisition data across the entire startup ecosystem (not just YC), Crunchbase has the broadest coverage — but expect enterprise pricing for API access.

For Institutional Investment Research

Recommendation: PitchBook — If you're a VC firm or institutional investor needing deep financial data, valuations, and cap table information, PitchBook is the industry standard — at enterprise pricing.
