OpenAI has restructured its leadership, appointing Barret Zoph to spearhead its enterprise AI sales, addressing competitive pressures in 2026.
OpenAI appointed Barret Zoph to lead its enterprise AI sales division, according to an internal memo cited by The Information. TechCrunch sought confirmation from OpenAI regarding this development.
Zoph rejoined OpenAI last week. He had previously served as co-founder and CTO at Thinking Machine Labs, an AI startup founded by former OpenAI CTO Mira Murati, since October 2024. Zoph had been OpenAI’s vice president of post-training inference from September 2022 to October 2024. His return places him in a new role critical to the company’s enterprise growth strategy.
OpenAI launched its ChatGPT Enterprise product in 2023, preceding Anthropic’s and Google’s enterprise offerings by more than a year. The company reports over 5 million business users for this product, with customers including SoftBank, Target, and Lowe’s.
Despite its early market entry, OpenAI’s market share is declining while its competitors are gaining traction. A December report from VC firm Menlo Ventures indicates that Anthropic holds a 40% market share in enterprise large language model usage, up from an estimated 32% in July. Menlo Ventures has invested in Anthropic.
Google’s Gemini has shown consistent adoption, according to Menlo Ventures. The company released its enterprise product last fall, maintaining an enterprise LLM usage market share that grew from 20% in July to 21% at year-end.
Conversely, OpenAI’s usage market share dropped from 50% in 2023 to 27% at the end of 2025. OpenAI CEO Sam Altman expressed concern in a recent internal memo regarding Google Gemini’s growth impacting OpenAI’s position. OpenAI’s CFO, Sarah Friar, stated in a blog post last Sunday that enterprise growth is a key focus for the company in 2026.
The company recently announced an expanded multi-year partnership with ServiceNow, providing ServiceNow customers access to OpenAI models.
