OpenAI has once again reshuffled its executive ranks, replacing its chief revenue officer just eight months after her appointment, as the ChatGPT maker accelerates efforts to expand its enterprise business ahead of a potential public listing.
The company announced Thursday that Denise Dresser, who joined in December to lead revenue and enterprise expansion, is departing "for other opportunities." Her successor is Dali Rajic, the former president and COO of cybersecurity firm Wiz, which was acquired by Google last year.
The transition underscores OpenAI's intensifying focus on commercial operations and enterprise sales, areas that have become critical as the company competes with rivals like Anthropic and Google in the race to monetize generative AI.
Leadership churn continues
Dresser's exit adds to a growing list of high-profile departures at OpenAI over the past year. Earlier this week, Brad Lightcap, one of the company's earliest executives and former COO, announced he was leaving after eight years. Lightcap joined in 2018, served as CFO for four years, and became COO in 2022 before moving to special projects earlier this year.
Other senior leaders have also stepped away. Chief Marketing Officer Kate Rouch left in April to focus on her cancer recovery, and Kevin Weil, who led the science organization, departed that same month. In July, Fidji Simo, a key figure in building OpenAI's commercial operations, reduced her role for health reasons but remains a part-time advisor. Bill Peebles, who led the discontinued Sora video project, has also left.
The turnover extends beyond the C-suite. In 2025, OpenAI lost its chief people officer, communications chief, a senior researcher who later founded an AI science startup, and at least seven researchers recruited by Meta.
AI talent war intensifies
While OpenAI's executive churn is notable, industry observers point out that such movement is becoming the norm in the fast-evolving AI sector. Competition for elite researchers and executives has intensified as tech giants and startups alike race to build more capable models.
OpenAI has also made significant hires. Earlier this month, Lilian Weng returned after a stint co-founding Mira Murati's Thinking Machines Lab. Weng, a respected AI safety researcher, rejoins as the company bolsters its research credibility. In June, Noam Shazeer, co-author of the landmark 2017 transformer paper, left Google for OpenAI—a move widely seen as a major recruiting win. That same month, Nobel laureate John Jumper departed Google for Anthropic, and Dean Ball, a former Trump administration AI policy advisor, joined OpenAI to lead a new Strategic Futures team.
Alphabet has also seen a leadership overhaul in its AI division, with Demis Hassabis stepping back from day-to-day management and several senior Gemini leaders, including Jeff Dean, exiting.
Enterprise growth takes center stage
The latest management changes come as OpenAI shifts its focus from purely building cutting-edge models to scaling its enterprise business and commercial infrastructure. The company reports over one billion weekly active users and two million business customers, but executives have acknowledged that revenue has not met every internal target, according to TechCrunch.
That shortfall has increased pressure to strengthen the enterprise segment before an IPO. Dresser was brought in to address this challenge, and her replacement signals a continued push for repeatable execution. Greg Brockman, OpenAI's co-founder and president, said Rajic will "turn what we've learned into repeatable execution as we build out the full system to make AI broadly useful for people and businesses."
According to Axios, Brockman has taken a more active role across the organization as the company prepares for its next phase of growth. The leadership reshuffle comes amid broader market dynamics, including oil-driven inflation concerns and volatility in AI-related stocks.
As OpenAI positions itself for a potential IPO, its ability to stabilize leadership and demonstrate consistent enterprise revenue growth will be closely watched by investors. The company's next moves could set the tone for the broader AI sector's public market debut.
