What is PostHog?

PostHog is an open-source, all-in-one product OS and data platform that combines the following (normally separate) tools under one roof:

  • Product analytics – funnel analysis, retention, user paths, SQL queries, etc.

  • Session replay – observe real users, events, console logs, and network requests

  • Feature flags – feature management, instant rollbacks, local evaluation

  • A/B testing – multivariate tests, automated statistical significance, JSON payloads

  • Surveys – NPS, free text, and multiple choice surveys

  • Customer data platform (preview) – data pipelines to support any use case

  • Data warehouse (closed beta) – a single source for all your important data

PostHog is built for engineers. We’re 100% self-serve and our pricing is transparent.

Who are we?

PostHog was founded by James Hawkins and Tim Glaser in January 2020, and was part of Y Combinator’s W20 batch.

We’re now ~35 people working all over the world. We’re 100% remote.

We value transparency, which is why our code is open to everyone, as is our company handbook.

Investors include GV, Y Combinator, Jason Warner (GitHub CTO), David Cramer (Sentry founder), and Dalton Caldwell (Managing Director, YC).

Why are we building PostHog?

Because the modern data stack sucks.

It’s a mess of point solutions that create gaps between product teams and the data they need to make good decisions.

With PostHog, you can:

  1. Research what new features your users might like with surveys.

  2. Test product ideas and solutions with A/B tests.

  3. Deploy them to some or all of your users using feature flags.

  4. Analyze how they use your product using product analytics.

  5. Observe the snags and frustrations they encounter using session replay.

All inside one platform. No complicated integrations. No expensive data engineers.
