OpenAI has lost two more senior employees, including the executive who led its private equity partnerships, as the artificial intelligence company faces continued leadership turnover. Paul Zimmerman, formerly OpenAI’s head of private equity, announced he has joined Alphabet Inc.’s Google to lead sales of Google’s AI technology to private equity firms and their portfolio companies.
Zimmerman’s departure comes just over a year after he joined OpenAI, according to his LinkedIn profile. His move to Google was disclosed in a professional update posted earlier this week. Separately, James Dyett, who described himself as OpenAI’s head of sales, announced he is leaving the company to join Thrive Capital, a venture capital firm that is a major investor in OpenAI.
The two departures follow the exit of three OpenAI executives in a single day in mid-April. That wave of resignations included senior leaders responsible for safety and policy, raising questions about internal stability at the company behind the ChatGPT chatbot.
Private Equity Becomes Key Battleground for AI Revenue
The loss of Zimmerman, who was specifically tasked with building OpenAI’s relationships with private equity firms, highlights an increasingly important revenue channel for AI companies. Over the past year, the generative AI race has shifted from consumer adoption to business and enterprise use cases. Companies like OpenAI, Anthropic, and Google are seeking larger and more predictable revenue streams from corporate customers, many of which are owned or controlled by private equity firms.
Private equity firms oversee thousands of portfolio companies and are actively looking for ways to improve operational efficiency through AI. Selling to these firms allows AI developers to reach multiple clients through a single relationship, making PE partnerships a strategic priority.
Partnership Activity Among AI Leaders
OpenAI is currently launching a $10 billion joint venture with private equity firms including TPG and Bain Capital, according to reports from Bloomberg and Reuters. The venture is designed to fund and deploy AI infrastructure. Rival Anthropic, backed by Amazon, recently announced a partnership with private equity firms worth $1.5 billion for similar purposes.
Separately, Bloomberg reported that Google is in talks with private equity giants Blackstone and KKR to bring its artificial intelligence models to their firms and portfolio companies. Google has not confirmed these discussions.
High-Profile Exits Raise Questions
Zimmerman declined to comment to Business Insider regarding his departure. Dyett, OpenAI, and Google did not immediately respond to requests for comment on the personnel changes or the ongoing partnership negotiations.
The string of departures comes at a critical time for OpenAI as it seeks to scale its enterprise sales operations and secure long-term revenue agreements. The company has not publicly addressed the recent turnover or announced replacements for Zimmerman or Dyett.
Analysts note that competition for AI talent and sales leadership remains intense among major technology firms. The ability to secure and retain executives with specialized experience in private equity and enterprise sales is seen as a key factor in determining which AI company gains an advantage in the business market.
Looking ahead, further movements of senior personnel between AI developers and their investors or competitors are expected as the industry continues to mature. OpenAI’s joint venture with TPG and Bain Capital is expected to proceed as planned, and the company has not indicated any changes to its business strategy in response to the recent departures.
