The story
Founded in 2021, Statsig built a developer-focused platform combining feature flags, A/B testing, and product analytics—positioning itself as the experimentation infrastructure layer for high-growth SaaS companies. The company scaled rapidly on usage-based billing, serving prominent customers like Notion, Brex, and Parafin. In September 2025, OpenAI acquired Statsig for $1.1 billion, integrating its experimentation capabilities into OpenAI's Applications business under Fidji Simo, with Vijaye Raji moving into the CTO of Applications role.
