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. GrowthBook's warehouse-native architecture is the platform's primary technical differentiator: instead of requiring companies to send event data to GrowthBook's infrastructure (as LaunchDarkly, Optimizely, and Statsig do), GrowthBook runs statistical analysis queries directly against the company's existing data warehouse where behavioral data already lives — eliminating the data duplication, latency, and privacy concerns of streaming events to a third-party platform. The feature flag SDK (supporting JavaScript, Python, Go, Ruby, PHP, Java, and mobile frameworks) handles the feature flag evaluation client-side, while the statistical analysis (frequentist and Bayesian testing, sequential testing, multiple comparison corrections) runs as SQL queries on the warehouse. The open-source model (MIT license, GitHub-hosted) provides the transparency and auditability that data-sensitive enterprises require. In 2025, GrowthBook competes in the feature flagging, A/B testing, and experimentation platform market with LaunchDarkly (feature management, $200M raised at $3B valuation), Statsig (experimentation platform, $43M raised), and Optimizely (digital experience platform, Insight Partners owned) for developer and product team experimentation infrastructure. The warehouse-native experimentation category (GrowthBook, Eppo) is growing as data teams resist adding another vendor data pipeline when their BigQuery/Snowflake instance already contains the behavioral data needed for statistical analysis. Y Combinator W22 backing positioned GrowthBook in the developer-first experimentation category during the PLG SaaS wave. The 2025 strategy focuses on growing GrowthBook Cloud (the managed tier with advanced collaboration, visual editor, and analytics features beyond the open-source core), building the multi-armed bandit and Bayesian experimentation modules for product teams, and expanding the enterprise security and access control features for regulated industry deployments. ## Frequently Asked Questions ### What is GrowthBook?
