OpenAI’s CTO for B2B Applications, Srinivas Narayanan, has announced he will step down from his role next week. In a post on X, he called his nearly three-year tenure an “incredible journey” and said he had informed company leadership earlier this month, marking another high-profile exit from the AI firm.

OpenAI is facing yet another high-profile departure. Srinivas Narayanan, an Indian-origin technology leader serving as Chief Technology Officer for B2B Applications at OpenAI since September 2025, has announced he will be stepping down from his role next week.

In a heartfelt post shared on X, Narayanan described his three-year tenure at the company as 'an incredible journey that felt more like ten,' and said he had informed OpenAI leadership of his decision at the start of the month.

As CTO of B2B Applications, Narayanan previously led engineering teams responsible for some of OpenAI's most popular products, including ChatGPT and its developer API platform. He joined OpenAI as Vice President of Engineering in April 2023 and was promoted to his current position in September 2025.

In the post addressed to his team, Narayanan reflected on the journey from OpenAI's earlier, leaner days. He described leading the Applied Engineering team "from when it was, 40 people on a single floor," before scaling it into an operation that helped build what he called "some of the fastest-growing products in history." He credited the growth entirely to his team, calling them "the most passionate, dedicated, and hard-working colleagues I have ever worked with."
