Barret Zoph leaves OpenAI after five months in enterprise sales role
Barret Zoph, OpenAI's head of enterprise AI sales, has left the company just five months after rejoining from Mira Murati's Thinking Machines Lab.
Barret Zoph has departed OpenAI for the second time, leaving his role as head of enterprise AI sales just five months after returning in mid-January. Zoph had rejoined OpenAI after a brief stint as co-founder and CTO of Thinking Machines Lab, the AI startup founded by former OpenAI CTO Mira Murati.
Zoph's return in January had been framed as a notable reversal—he had left to help launch Murati's competing venture, only to come back to lead enterprise AI sales focused on driving adoption of OpenAI's models among large business customers. The reasons for his latest departure have not been disclosed, and OpenAI has not commented publicly on the exit.
Talent churn at the top
The move underscores the fluid movement of senior talent between OpenAI and emerging AI startups. Zoph's trajectory—from OpenAI to Thinking Machines Lab as CTO, then back to OpenAI in a commercial role—reflects both the competitive pressure OpenAI faces from well-funded rivals and the appeal of early-stage ventures to established executives. His departure marks another high-profile exit from OpenAI's leadership during a period of significant executive turnover.
