OpenAI acquires Statsig for $1.1B, names founder as CTO OpenAI has just announced its acquisition of Statsig, a Seattle-based startup focused on product experimentation and analytics, for $1.1 billion in an all-stock deal. The move marks another major step as OpenAI expands beyond research and into practical applications that millions and soon billions of people might use every day. What is Statsig, and Why Did OpenAI Want It? Statsig builds tools that let tech teams run rapid product experiments, analyze features, and roll out updates confidently using real-time data. Their software helps companies ship better products faster with A/B testing, feature flags, session replay, and detailed analytics. Firms like Microsoft, Notion, and Atlassian already trust Statsig’s platform to manage changes and learn from user feedback.<a target="_blank" href="https://www.linkedin.com/company/statsig"></a> For OpenAI, integrating Statsig means its apps especially ChatGPT, Codex, and others can test new features and improvements at scale, with data-driven guidance to ensure users get the best possible experience.<a target="_blank" href="https://www.vktr.com/ai-news/openai-buys-statsig-for-11b-in-all-stock-deal-founder-vijaye-raji-named-cto-of-applications/"></a> Leadership Changes and Strategy A standout detail is that Statsig’s founder and CEO, Vijaye Raji, will join OpenAI as CTO of Applications, reporting to Fidji Simo, the former Instacart CEO now leading OpenAI’s applications division. Raji will guide the engineering and product strategy behind OpenAI’s most visible projects.<a target="_blank" href="https://www.cnbc.com/2025/09/02/openai-buys-statsig-for-1point1-billion-hires-ceo-as-applications-exec.html"></a> Statsig will continue operating independently from its Seattle office and serving its existing customers, at least for now. The acquisition is pending regulatory approval, but industry experts say this is a smart match combining world-class product development speed with OpenAI’s ambition to scale real-world AI applications.<a target="_blank" href="https://www.geekwire.com/2025/openai-acquires-statsig-for-1-1b-names-ceo-to-key-exec-role-in-surprise-exit-for-seattle-area-unicorn/"></a> Topics and Implications Why It’s Not Just Another Acquisition Statsig’s platform makes it easier to know when a new feature is truly helping users and when it isn’t. By weaving that capability into OpenAI’s stack, there’s potential for AI-powered apps to become more useful and relevant, faster than ever. OpenAI is investing in tools that make feedback loops tighter, which is a subtle but important shift from research labs to hands-on product teams.
