OpenAI acquires Statsig for $1.1 billion and appoints new CTO.

OpenAI has made a significant acquisition in its expansion journey by purchasing the startup Statsig for $1.1 billion. This move aligns with the intense buying activity that the company has been engaged in recently, leveraging the capital raised and the increase in its stock value to drive growth in new areas.

Details of the Acquisition

Statsig is a software development company that specializes in product experimentation. Its technology allows organizations to test various functionalities and use real-time data to optimize their operations. With this acquisition, OpenAI not only enriches its technological portfolio but also integrates Vijaye Raji, CEO of Statsig, who will assume the role of Chief Technology Officer (CTO) in OpenAI's applications unit. This new role will place him under the leadership of Fidji Simo, who has been leading OpenAI's applications business since May.

In a message posted on LinkedIn, Raji expressed his excitement about joining the OpenAI team: "Working with the incredible team at OpenAI to build AI-powered experiences at scale for people and businesses is a rare and significant opportunity. Doing it with the support of the tools we built at Statsig makes it even more special."

Independent Operation and Future of Statsig

Despite the acquisition, OpenAI has confirmed that Statsig will continue to operate independently from its office in Seattle. This strategy suggests that OpenAI plans to preserve Statsig's identity and culture while benefiting from its technology and expertise.

The announcement also underscores OpenAI’s focus on creating AI-driven experiences. Fidji Simo praised Raji, highlighting his remarkable track record in building new products and systems for both consumers and large-scale businesses.

Recent Acquisition Activity

The purchase of Statsig is part of a series of aggressive investments by OpenAI. Previously, the company acquired IO, Jony Ive's artificial intelligence device startup, for nearly $6.5 billion in an all-stock deal, marking a clear entry of OpenAI into the hardware market. There was also an earlier acquisition in 2024 of Rockset, a company specializing in analytical databases, although the amount of that transaction was not disclosed.

Earlier this year, OpenAI had attempted to acquire Windsurf, an AI-assisted coding tool, for $3 billion, but the negotiation did not proceed, and Google ended up incorporating the co-founder of the startup in a licensing deal valued at $2.4 billion.

Reflection from Vijaye Raji

Raji also shared his thoughts on the future of Statsig in his new role, stating, "The journey with Statsig has been deeply rewarding, bringing me to this moment and reinforcing my belief that we will continue to help teams launch better software every day."

With this move, OpenAI underscores its commitment to innovation and technological development in order to empower businesses with sophisticated AI-based tools. This acquisition reaffirms OpenAI's ability to integrate advanced technologies into its platform, thus expanding its reach in the software development space.
