About PostHog

PostHog, founded during Y Combinator's W20 cohort in 2020, is transforming the landscape of product development by offering a fully integrated, open-source analytics platform. The platform combines essential tools like product analytics, heatmaps, session recording, and A/B testing into a unified solution, negating the need for multiple integrations. This approach significantly streamlines the product development process.

The platform, compliant with key security and privacy standards such as SOC2, GDPR, and HIPAA, is available for hosting in both the US and EU. Notably, PostHog achieved the most successful B2B software launch on Hacker News since 2012, rapidly acquiring over 100,000 users and experiencing a 97% growth predominantly through word of mouth.

With a significant $75.00M Series E investment on 01 September 2025 led by notable investors such as Y Combinator, GV, Stripe, and Peak XV Partners, PostHog is well-positioned for further expansion. Its innovative platform and impressive market traction make it a compelling prospect in the Analytics and Developer Tools sectors.
