Statsig is a product development platform combining experimentation (A/B testing), feature flags, product analytics, session replay, and web analytics in one toolkit for engineers, data scientists, and product managers. OpenAI acquired Statsig in a ~$1.1 billion all-stock deal announced in 2025, with founder Vijaye Raji becoming OpenAI's CTO of Applications. In May 2026 Amplitude took over the Statsig brand, platform and customers, while the original Statsig team remained at OpenAI.
