OpenAI acquires product testing startup Statsig for $1.1B, reshuffles leadership

OpenAI has acquired product testing and experimentation startup Statsig in an all-stock deal valued at approximately $1.1 billion. The agreement, announced on 2 September 2025, strengthens OpenAI’s push into application-level development and follows a series of senior leadership changes.

Acquisition details

The deal is based on OpenAI’s current valuation of around $300 billion. Statsig, founded in 2021 by former Meta executive Vijaye Raji, builds product experimentation platforms that enable companies to run large-scale feature testing and A/B experiments. Its technology is widely used to manage product reliability and performance across enterprise applications.

Statsig’s tools allow companies to deploy and measure product features at scale, offering insights into performance and adoption. The acquisition brings OpenAI additional infrastructure to enhance its flagship products, including ChatGPT and developer platforms, ensuring faster iterations and controlled rollouts.

Leadership appointments

As part of the transaction, Statsig founder Vijaye Raji will join OpenAI as Chief Technology Officer of Applications. He will oversee engineering across OpenAI’s suite of consumer and enterprise-facing products. Raji will report to Fidji Simo, who was appointed CEO of Applications in August 2025.

OpenAI also announced further leadership restructuring. Srinivas Narayanan, formerly a senior engineering leader, has been promoted to Chief Technology Officer of B2B Applications. Narayanan will lead OpenAI’s enterprise and government-focused initiatives and report directly to Chief Operating Officer Brad Lightcap.

Kevin Weil, previously Chief Product Officer, will move to the role of Vice President of AI for Science within OpenAI’s research division. He will report to Chief Research Officer Mark Chen. The ChatGPT product team, previously under Weil’s supervision, will now fall within Simo’s Applications division.

Expanding applications division

The leadership changes are intended to streamline OpenAI’s product engineering and align development with the company’s expanding focus on consumer and enterprise applications. The integration of Statsig’s platform is expected to support OpenAI in building new features and services with greater speed and reliability.

The restructuring also consolidates OpenAI’s applications strategy under Fidji Simo, who will now oversee both consumer-facing platforms and the product teams previously reporting to Weil. The moves highlight OpenAI’s transition towards building scalable applications alongside its research and model development.
