ExploreYC

ExploreYC is a read-only REST API that provides comprehensive access to Y Combinator and Andreessen Horowitz (a16z) portfolio data. Developers, investors, and analysts can retrieve detailed information on funding rounds, company stages, exits, founder profiles, and more — all delivered via clean JSON over HTTPS. With a generous free tier and scalable paid plans, ExploreYC makes startup ecosystem intelligence accessible to everyone from hobbyist builders to enterprise teams.

Product Highlights

• Comprehensive Portfolio Data: Access detailed information on thousands of YC and a16z companies including funding history, current stage, exit status, and founder backgrounds.
• Simple REST API: Clean, well-documented endpoints return JSON over HTTPS with no complex authentication flows — just a bearer token or header key.
• Transparent Rate Limiting: Every response includes clear rate limit headers (X-RateLimit-Remaining, X-RateLimit-Reset) so you always know your usage status.
• Interactive Documentation: Built-in Swagger UI lets you explore and test endpoints directly in the browser before writing a line of code.
• Flexible Pricing Tiers: Start free with 5 requests per day, then scale through Starter (500/day), Pro (5,000/day), or custom Enterprise plans as your needs grow.
