OpenAI acquires Statsig for $1.1 billion and appoints CEO as head of applications

OpenAI announced the acquisition of Statsig , a startup specializing in feature testing and real-time data usage. The deal was worth $1.1 billion, CNBC reports.

Statsig founder and CEO Vijay Raji will become the CTO of OpenAI's applications division and will work under Fiji Simo, the former CEO of Instacart, who took over the leadership in May.

Statsig will continue to operate independently and serve clients from its Seattle office, OpenAI said. The deal is subject to regulatory approval. Raja said the partnership with OpenAI is a “rare and unique opportunity” to scale Statsig’s tools into global AI solutions.

The acquisition fits into OpenAI's aggressive expansion strategy. In May, the company made its largest acquisition to date, Jony Ive's AI device startup IO. The deal was worth about $6.5 billion in a stock swap, effectively marking OpenAI's entry into the hardware space.

Earlier, in 2024, the company bought analytics platform Rockset , and in early 2025, it planned to acquire AI coding tool Windsurf for $3 billion. However, the deal fell through, and the startup eventually entered into a licensing agreement with Google for $2.4 billion.
