Key Takeaways: OpenAI’s Acquisition of Statsig and Leadership Expansion
OpenAI is acquiring Statsig, a trusted experimentation platform used for A/B testing, feature flagging, and real-time decisioning.

OpenAI Expands Applications Leadership with Vijaye Raji
OpenAI announced it is expanding its Applications leadership team, the group responsible for turning AI research into products for hundreds of millions of people and businesses.
Following the acquisition of Statsig, Vijaye Raji will step into the role of CTO of Applications, reporting to Fidji Simo, CEO of Applications. In this role, Raji will lead product engineering for ChatGPT and Codex, overseeing infrastructure, integrity, and core systems.
Raji brings more than a decade of experience from Meta, where he scaled consumer engineering systems, along with his entrepreneurial background founding Statsig.
“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,” said Fidji Simo, CEO of Applications at OpenAI.
Statsig Acquisition: Strengthening Experimentation at OpenAI
As part of the transition, OpenAI is acquiring Statsig, an experimentation platform that enables rapid A/B testing and data-driven decision-making. The platform has already been instrumental in helping OpenAI ship products quickly and iterate effectively.
By bringing Statsig in-house, OpenAI aims to accelerate experimentation across its Applications division and enhance the user experience for both individuals and businesses.
“Joining OpenAI as CTO of Applications is an extraordinary opportunity to bring my experience scaling consumer and enterprise products to a mission I deeply believe in: advancing AI in ways that are capable of solving hard problems, reliable, and truly beneficial to people everywhere. The journey with Statsig has been deeply gratifying, leading me to this moment and giving me conviction that we will continue helping teams ship better software every day,” said Vijaye Raji, incoming CTO of Applications.
Statsig to Continue Independent Operations
Once the deal closes, Statsig employees will join OpenAI but will continue serving their existing customer base from the company’s Seattle office. OpenAI emphasized that the integration will be gradual to ensure continuity for current customers and allow the team to remain focused on experimentation.
The acquisition is still pending regulatory approval and other standard closing conditions.
