OpenAI announced plans to acquire Statsig, a Seattle-based product experimentation platform, in a stock transaction valued at approximately $1.1 billion. The move, one of OpenAI’s largest acquisitions to date, comes amid a broader leadership restructuring under Fidji Simo, the newly appointed CEO of Applications. 

Following the deal, Statsig founder and CEO Vijaye Raji will join OpenAI as Chief Technology Officer of Applications, reporting directly to Simo. “Vijaye has a remarkable record of building new consumer and B2B products and systems at scale,” Simo said, noting that his expertise will accelerate OpenAI’s push to translate AI breakthroughs into safe, widely usable applications. 

Founded in 2021, Statsig specializes in experimentation infrastructure, including A/B testing, feature flagging, and real-time decisioning. Its platform has been widely adopted by leading technology firms, including OpenAI itself, to optimize product development and user experiences. 

The acquisition will allow OpenAI to bring these capabilities in-house while keeping Statsig’s operations running independently from its Seattle headquarters during the integration period. The transaction remains subject to regulatory approval. 

The deal follows OpenAI’s landmark $40 billion capital raise earlier this year at a $300 billion valuation.
