OpenAI announced the acquisition of Statsig, a Seattle-based product testing startup, in an all-stock deal valued at $1.1 billion. Statsig, founded by Vijaye Raji, specializes in A/B testing, feature flagging, and real-time decision-making tools, already used by OpenAI and other tech firms like Eventbrite and SoundCloud. The acquisition aims to enhance OpenAI’s product development and experimentation capabilities for its AI applications, including ChatGPT and Codex. Vijaye Raji, an Indian-origin engineer from Puducherry with over 20 years of experience, including a decade at Microsoft and Meta, has been appointed as OpenAI’s Chief Technology Officer (CTO) of Applications. Reporting to Fidji Simo, CEO of Applications, Raji will lead product engineering for ChatGPT and Codex, focusing on scaling infrastructure and ensuring safe, intuitive AI tools. Statsig will continue to operate independently from its Seattle office, serving its existing customers, while its employees join OpenAI. The deal, subject to regulatory approval, follows OpenAI’s $6.5 billion acquisition of Jony Ive’s io Products, signaling a strategic push to strengthen its consumer and enterprise AI offerings.
