OpenAI acquires Statsig, a product experimentation and feature management platform. The all-stock transaction is valued at approximately $1.1 billion, based on OpenAI’s most recent $300 billion valuation.

As part of the deal, Vijaye Raji, Statsig’s founder and CEO, will join OpenAI as Chief Technology Officer of Applications, reporting to Fidji Simo, OpenAI’s CEO of Applications. In this role, Raji will oversee product engineering across ChatGPT, Codex, and OpenAI’s core application infrastructure.

“Statsig has built a world-class platform that empowers teams to innovate and iterate at scale,” said Fidji Simo. “By bringing Statsig into OpenAI, we’re accelerating our mission to deliver AI applications that are reliable, user-driven, and constantly improving.”

Statsig will continue to operate independently from its Seattle headquarters, retaining its culture and product focus while gaining access to OpenAI’s resources and ecosystem. The two teams will work in parallel as regulatory approval is finalized.

“Joining OpenAI allows us to apply Statsig’s experimentation capabilities to some of the most widely used AI applications in the world,” said Vijaye Raji. “Together, we’ll be able to ship better products, faster—and at a scale we could only dream of before.”

The acquisition comes as OpenAI continues to expand its application portfolio amid accelerating growth. The company recently announced an annualized revenue run rate of $12 billion through July 2025 and projects to surpass $20 billion by year-end.

With the addition of Statsig, OpenAI is strengthening its ability to scale experimentation, speed up product development cycles, and ensure its applications evolve in step with user needs.
