    Lifecycle analysis

    Product Analytics Team

    Lifecycle analysis enables you to dig deeper into your events with a breakdown of the users who performed an event into new, returning, and resurrecting users. In addition, it also shows you the churn on for the specified time period.

  • Session replay

    Session Replays

    Monitoring Team

    We added the first version of our session recording product, which is now known as session replays. The first version was rudimentary, enabling you to watch user sessions and automatically exclude sensitive information. Since then we've added a lot of new features!

    ClickHouse support

    Pipeline Team

    ClickHouse is, in simple terms, a very fast database. Until this point we've been using Postgres, but we've now made the change to switch to ClickHouse for larger event volumes. At the time we made this change we were handling nine-figure numbers of events each day, and ClickHouse drastically sped everything up.

    PostHog FOSS launched

    Product Analytics Team

    As an open core company, we have to reconcile our open source efforts with our ability to generate revenue. Generating revenue is how we're able to sustain our extensive work in the open source space.

    Thus, after a lot of brainstorming and calls with the likes of Sid Sijbrandij, CEO of GitLab, we settled on a business model that allows PostHog to be a sustainable company in the open source space.

    This led to the creation of a new repository called posthog-foss, which is a mirror of the main repository without proprietary code. Want to run your own open source version of PostHog under a permissive MIT license? Now you can.

    Offsite: Italy

    Exec Team

    Once a year, the entire company gets together for a week. For our first company offsite, we went to Italy and spent the week working hard, having fun and arguing about the merits of pineapple on pizza.

    Launched open source analytics on HackerNews

    Exec Team

    We launched on Hacker News with our MVP, just 4 weeks after we started writing code.

    The response was overwhelmingly positive. We had over 300 deployments in a couple of days. 2 weeks later, we'd gone past 1,500 stars on GitHub.
