OpenAI Adds Statsig to Its Billion-Dollar Acquisition Streak

OpenAI announced the acquisition of Statsig, a Seattle-based product experimentation platform, in an all-stock deal valued at $1.1 billion. The agreement, which is subject to regulatory approval, makes Statsig one of the most significant purchases in OpenAI’s history and adds another major transaction to its growing list of acquisitions.

As part of the deal, Statsig’s founder and CEO Vijaye Raji will join OpenAI as Chief Technology Officer of Applications, reporting to Fidji Simo, CEO of the company’s Applications division. Raji will oversee engineering for ChatGPT and Codex, with responsibilities extending across core systems, infrastructure, and integrity.

Leadership Changes

OpenAI is coupling the Statsig acquisition with a significant reshaping of its leadership team. Fidji Simo, who took charge of OpenAI’s Applications division earlier this year, welcomed Raji’s appointment by pointing to his track record across both consumer and enterprise technology. She described him as a leader with “a remarkable record of building new consumer and B2B products and systems at scale,” adding that his experience will be central to developing “safe applications that empower people, help companies increase their impact, and allow developers to build faster and better products.”

For Raji, the move represents both continuity and expansion. After nearly a decade each at Microsoft and Meta, he launched Statsig in 2021 to bring large-scale experimentation tools to a wider audience. Reflecting on the transition, he called the new role “an extraordinary opportunity to bring my experience scaling consumer and enterprise products to a mission I deeply believe in.” The Statsig journey, he added, “has been deeply gratifying, leading me to this moment and giving me conviction that we will continue helping teams ship better software every day.”
