OpenAI has agreed to acquire Statsig in a $1.1 billion all-stock deal, gaining not only the startup’s experimentation platform but also its founder.
Under the structure, the founder and his team come on board as part of the package, tied to OpenAI’s own roughly $300 billion valuation.
Statsig’s founder, Vijaye Raji, will step directly into a new leadership post at OpenAI as chief technology officer of Applications, placing him in charge of ChatGPT, Codex, and critical infrastructure and integrity systems.
Statsig has carved out a place in the crowded software market by offering a full-stack experimentation platform that goes beyond simple feature flagging. Built on Raji’s experience, who led product experimentation at Facebook, the system auto-computes key business metrics such as retention and revenue impact, making it easier for companies to ship, test, and measure new features without a heavy engineering lift. The approach brings “Big Tech-grade” A/B testing to businesses of all sizes.
Says OpenAI in an announcement,
“[Raji’s] experience as founder and CEO of Statsig, and a decade leading large-scale consumer engineering at Meta, brings both entrepreneurial vision and operating expertise to scale our next generation of products.”
Statsig itself highlights its reach, stating that “3.5 M+ customers” benefit from its experimentation tools. But at a $1.1 billion valuation, the deal equates to about $314 per user.
The transaction remains subject to regulatory approval, but the move comes at a moment when AI companies are racing to secure top technical leadership, with demand for experienced engineers and product executives outstripping supply across the industry.
