Vijaye Raji will step into a new role as CTO of Applications⁠, reporting to Fidji Simo, following the acquisition of Statsig. As a hands-on builder and trusted leader, Vijaye will head product engineering for ChatGPT and Codex, with responsibilities that span core systems and product lines including infrastructure and Integrity. His 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.

“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, and his leadership will help turn that progress into safe applications that empower people with many new tools to improve their lives, help companies increase their impact and allow developers to build faster and better products.”

As part of this transition, we’re acquiring Statsig, one of the most trusted experimentation platforms in the industry—powering A/B testing, feature flagging, and real-time decisioning for some of the world’s most innovative companies, including OpenAI.

Vijaye and his team founded Statsig on the belief that the best products come from rapid experimentation, tight feedback loops, and data-informed decision-making.
