Case Study: How Supabase 10X'd weekly new user acquisition with PostHog

Key results

The challenge

Supabase, an open-source developer platform, wanted to grow new user acquisition but was running only one to two experiments per month. Its growth team needed faster, clearer insight into what drove sign-ups across a fast-moving developer audience.

The solution

Supabase adopted PostHog for product analytics and experimentation, increasing the pace of tests from one to two per month and using the data to focus on high-leverage growth drivers. The team combined analytics with experiments to iterate on what moved new-user acquisition.

The results, in context

Supabase reported a 10X increase in weekly new user acquisition compared with a year earlier, up from a prior pace of one to two experiments per month before PostHog. The story is published on PostHog's customer hub and dated June 15, 2025.
