## About

GrowthBook is a San Francisco-based open-source feature flagging and A/B testing platform founded in 2021 by Jeremy Edelblut and Graham McNicoll. The platform is designed as an affordable alternative to LaunchDarkly and Optimizely, offering feature flags, gradual rollouts, and statistical A/B testing powered by Bayesian analysis. GrowthBook connects directly to your existing data warehouse (BigQuery, Redshift, Snowflake, etc.) for experiment analysis rather than requiring you to send data to a third-party system. The platform can be self-hosted for free or used as a managed cloud service. GrowthBook raised $7M in seed funding and has seen rapid adoption among engineering and product teams.
