About

GrowthBook is a San Francisco-based open-source feature flagging and A/B testing platform — backed by Y Combinator (W22) — providing engineering teams and product managers with a self-hostable, warehouse-native experimentation system that connects directly to Snowflake, BigQuery, Redshift, Databricks, and Postgres data warehouses to run A/B tests against existing event data without requiring a separate third-party analytics SDK or data pipeline. Founded in 2020 and generating $5 million in revenue in 2024 with a 21-person team, GrowthBook operates under an open-core model (MIT license for the core platform, paid GrowthBook Cloud for the managed option) that has built a developer-first community and significant self-hosted installed base.
