Company Overview
PostHog is a software company that provides an open-source, all-in-one platform for product engineers. Founded in 2020 by James Hawkins and Tim Glaser, the company started as a product analytics tool and has since expanded to offer a comprehensive suite of over a dozen products, including session replay, feature flags, A/B testing, a data warehouse, and AI-powered tools. The company's mission is to provide engineers with all the tools they need to build successful products. PostHog operates on a transparent, usage-based pricing model with a generous free tier, which has helped it attract a large user base. The company is venture-backed by prominent investors such as Y Combinator, GV (formerly Google Ventures), and Stripe, and it raised a $70 million Series D round in June 2025 at a $920 million valuation. While fully remote, PostHog is headquartered in San Francisco, California.
