Overview

GrowthBook is an open source platform to help companies make data-driven product decisions with feature flags and A/B tests.

Existing SaaS solutions like LaunchDarkly require a company to send all of their data to them. This results in high costs, data compliance issues, and vendor lock-in. As a result, many companies end up building their own platforms in-house, which can take thousands of hours of work and lots of headaches. To solve this, GrowthBook uses a company's existing data infrastructure and business metrics.

We believe feature flags and experimentation are the right way to build products at scale and that they will become a standard part of the development process. GrowthBook is well positioned to be a leader in this growing market.

Trusted by the world's leading data science teams, GrowthBook is built for your teams and agents to run rigorous tests at scale and learn faster.
