Five months after returning to OpenAI, Barret Zoph — the company's head of enterprise AI sales — has departed, according to internal communications seen by The Verge. Zoph posted a goodbye message in OpenAI's Slack channels, marking his second exit from the organization in less than two years.
Zoph originally left OpenAI in fall 2024 to join Mira Murati's competitor, Thinking Machines Lab, as co-founder and CTO. However, his tenure there was short-lived. In January 2026, Thinking Machines Lab announced it had parted ways with Zoph following reports of alleged misconduct involving an undisclosed relationship with a colleague. Murati posted on X at the time that the company had 'parted ways' with Zoph and that he would be replaced as CTO.
Just weeks later, Zoph returned to OpenAI in mid-January 2026. The company announced he would lead its push into enterprise AI sales — a critical role as OpenAI shifted its focus away from experimental projects and toward key revenue drivers like enterprise and coding. The move was part of a broader strategy to prepare for its planned initial public offering. Fidji Simo, OpenAI's CEO of Applications, wrote on X that the company was 'excited to welcome Barret Zoph, Luke Metz, and Sam Schoenholz back' and that the decision had been in the works for several weeks. Metz and Schoenholz had also left OpenAI in 2024 to join Thinking Machines Lab and returned alongside Zoph.
Zoph's latest departure raises questions about OpenAI's ability to retain top talent in its enterprise division. The company has been aggressively building out its sales team to compete with other AI giants and enterprise software providers. However, the revolving door of executives has been a persistent challenge. In recent months, OpenAI has seen a series of high-profile resignations, including key researchers and leaders in safety and policy.
The enterprise AI market is expected to grow from $12 billion in 2025 to over $50 billion by 2030, according to industry analysts. OpenAI is positioning itself to capture a significant share of this growth. The company recently launched a dedicated enterprise sales team under Zoph, with specialized account managers for different verticals such as healthcare, finance, and manufacturing. Zoph had also been involved in developing customized AI solutions for clients, including a chatbot for a major insurance company and a document analysis tool for a law firm. These initiatives are now at risk of losing momentum without a permanent leader.
Zoph's background includes a PhD in computer science from Stanford University, where he focused on natural language processing and reinforcement learning. He joined OpenAI in 2020 and quickly rose through the ranks, contributing to the development of GPT-4 and other foundational models. He was widely regarded as a talented engineer and leader, though his frequent job changes have drawn scrutiny. Before OpenAI, Zoph worked at Google Brain, where he co-authored several influential papers on neural architecture search.
The circumstances surrounding Zoph's departure from Thinking Machines Lab were particularly notable. The allegations of misconduct were never fully detailed, but they underscored the intense scrutiny that personal relationships within AI companies can attract. Murati's handling of the situation was seen as decisive but also highlighted the challenges of maintaining a safe and productive work environment in high-pressure startups. The episode also strained relations between Thinking Machines Lab and OpenAI, with Murati and Sam Altman already at odds after Murati's brief stint as CEO during the 2023 boardroom coup.
Thinking Machines Lab itself has faced its own tensions with OpenAI. Murati temporarily replaced Sam Altman as CEO during the November 2023 boardroom coup, which led to a period of instability. During the subsequent OpenAI trial, Murati testified that she could not fully trust everything Altman said, revealing deep fractures within the company. The departure of several employees to Murati's new venture initially seemed like a brain drain for OpenAI, but the return of Zoph, Metz, and Schoenholz suggested that the rivalry was not as clear-cut as it seemed.
Now, with Zoph out again, OpenAI will need to find a new head of enterprise sales at a critical juncture. The company is reportedly targeting a valuation of over $300 billion in its IPO, which could come as early as 2027. OpenAI's IPO is expected to be one of the largest tech IPOs in history, with bankers projecting a valuation between $250 billion and $350 billion. Revenue growth has been strong, driven largely by consumer subscriptions and API usage, but enterprise adoption is seen as the next major growth driver. The company has been working to clean up its financial reporting and governance structure to meet public market requirements, and executive stability is a key concern for potential investors.
The timing of Zoph's departure is awkward. OpenAI recently announced several major enterprise deals, including partnerships with financial services firms and healthcare providers. Losing the executive responsible for these relationships could disrupt ongoing negotiations and implementation efforts. Competitors like Google DeepMind, Anthropic, and Microsoft are likely to use this instability to their advantage. Already, Anthropic has poached several OpenAI sales executives in recent months, and Google has expanded its enterprise AI consulting team.
Zoph's announcement in Slack was described as brief and gracious, thanking his colleagues and expressing confidence in the team he helped build. He did not specify his next steps, but sources suggest he may be considering starting his own AI venture or joining another top-tier lab. Given his history of quick moves, it is unlikely he will remain out of the industry for long. Some speculate he might rejoin Thinking Machines Lab, but that seems unlikely given the circumstances of his departure from there.
The broader implications for OpenAI are concerning. The company has been praised for its technical achievements but criticized for its corporate governance and leadership churn. The boardroom drama in 2023, followed by a series of executive departures, has created a perception of instability. Investors are closely watching how the company manages its talent pipeline as it moves toward an IPO. A stable leadership team is often a prerequisite for a successful public offering, and OpenAI's track record raises red flags.
OpenAI has not commented beyond confirming Zoph's departure. The company's spokesperson declined to provide additional details about the transition plan. Insiders say that the enterprise sales team is strong enough to continue without a permanent leader for a short time, but a permanent replacement will need to be named quickly to maintain momentum. The board is reportedly considering both internal promotions and external candidates. Luke Metz and Sam Schoenholz, who returned alongside Zoph, have remained at OpenAI and continue to work on model architectures and training infrastructure. Their decision to stay suggests that not all returnees are leaving again, but Zoph's departure may prompt others to reassess their positions.
Zoph's career trajectory is emblematic of the AI talent wars. Top researchers and executives often jump between companies, driven by stock options, mission alignment, or personal relationships. The competition for talent is fierce, and even a company with OpenAI's resources can struggle to retain people. The recent compensation packages at OpenAI have been generous, including equity worth tens of millions of dollars for top executives, but even those incentives have not been enough to ensure longevity. Some insiders point to a cultural issue, where the intense pressure and public scrutiny take a toll on employees.
As the AI industry matures, stability in leadership will become increasingly important. OpenAI's ability to keep key executives in place could determine whether it can sustain its lead over competitors. Zoph's second departure in less than two years raises doubts about whether the company can provide the environment needed to retain top talent. The enterprise push is especially vulnerable because customer relationships often rely on personal trust in the sales leadership. Clients may delay purchasing decisions until a new head is in place and the strategy is reaffirmed.
For now, the AI community is watching to see where Zoph lands next. His skills in enterprise sales and technical leadership are in high demand. Meanwhile, OpenAI must focus on filling the gap and reassuring its enterprise customers that the departure will not affect service or innovation. The coming weeks will be critical as the company navigates yet another leadership change. Whether Zoph's exit becomes a footnote or a turning point in OpenAI's history remains to be seen, but it is a stark reminder that even the most prominent AI companies are not immune to the churn that plagues the industry.
