PostHog

PostHog builds an open‑source, all‑in‑one platform for product teams and engineers that combines product analytics, session recordings, feature flags, A/B testing, a built‑in data warehouse, and AI‑assisted analysis. The company offers self‑hosted and hosted plans (US/EU) with SOC 2, GDPR, and HIPAA compliance. Founded in 2020 in San Francisco after Y Combinator’s W20 cohort, PostHog monetizes through paid cloud and enterprise subscriptions.
