PostHog

PostHog for Startups provides $50,000 in credits for their open-source, all-in-one product analytics platform — covering events, session replays, API calls, and survey responses for one year. Includes exclusive founder merch and partner benefits: $1,500 off Incident.io Teams plan, 50% off Speakeasy for 6 months (API/SDK tooling), and $5,000 in Chroma credits (AI search and retrieval). PostHog is used by Y Combinator ('PostHog is central to how we do that at Y Combinator' — Cat Li, Product & Engineering Lead) and backed by Concept Ventures.

The platform includes product analytics, session replay, feature flags, A/B testing, surveys, and data warehouse — all open-source. Compared to competitors: PostHog is the only startup program offering open-source product, free merch, and partnership opportunities alongside credits.
