OpenAI poaches Meta vet Vijaye Raji as CTO, acquires Statsig

OpenAI is making a leadership grab that signals just how serious it is about turning lab breakthroughs into polished products used by hundreds of millions. The company announced that Vijaye Raji, founder and CEO of the experimentation platform Statsig, will become its new CTO of Applications, reporting directly to CEO of Applications Fidji Simo. The move coincides with OpenAI acquiring Statsig outright — a platform it already uses heavily for A/B testing and feature flagging.

Raji is not a newcomer to massive-scale consumer engineering. He spent a decade at Meta, leading teams that built products for billions of users. That kind of scar tissue around scaling infrastructure while shipping quickly is precisely what a company racing to turn GPT-5, Codex, and whatever comes next into reliable, intuitive tools desperately needs. Simo framed the hire bluntly: “Vijaye has a remarkable record of building new consumer and B2B products and systems at scale. He’s joining at a time when our models are opening entirely new ways to build.”

Statsig itself has been a quiet workhorse for the industry, powering real-time decisioning for companies that need to know what actually works and what doesn’t. OpenAI was already a customer, so pulling it in-house is less a pivot and more of a vertical integration play. The acquisition means Statsig’s team becomes OpenAI employees, operating independently from Seattle for now. Raji, for his part, talked up the mission in classic tech-executive style, calling the role “an extraordinary opportunity” to advance AI that is “truly beneficial to people everywhere.”

What’s left unsaid is how messy this integration could get for Statsig’s existing customers. OpenAI promises continuity and a “measured approach,” but every acquisition starts with that line. The real test is whether Raji can keep the Statsig engine humming for outsiders while injecting its speed-obsessed culture into ChatGPT’s product engineering. If he pulls it off, OpenAI’s product velocity could leave competitors gasping. If not, it’s another talent acquisition that fizzles quietly.
