Microsoft ( MSFT )-backed (MSFT) OpenAI said Tuesday that it will acquire Statsig, a product-testing startup.

The deal is worth $1.1 billion, several media outlets reported.

OpenAI said in a blog post that Statsig's staff will become OpenAI employees once the acquisition is completed, but that Statsig will continue to operate independently from its Seattle office.

OpenAI also said it will name the founder and chief executive officer of Statsig, Vijaye Raji, as its chief technology officer of applications.

Vijaye will lead product engineering for ChatGPT and Codex, overseeing core systems and product lines, OpenAI said.

Statsig said in May that it had raised $100 million in Series C funding at a $1.1 billion valuation.
