San Francisco, California — Tensions have surfaced at Thinking Machines Lab following a controversial incident involving its cofounder and former chief technology officer, Barret Zoph. Allegations of misconduct concerning an inappropriate relationship with a fellow employee prompted management to confront Zoph last summer, according to multiple sources familiar with the matter.

While the employee, whose name has not been disclosed to protect their privacy, held a leadership position in a different department, they are no longer with the organization. Following the pivotal conversation with Mira Murati, the startup’s CEO, Zoph reportedly began exploring opportunities with rival companies, indicating a breakdown in trust between him and the leadership.

As discussions unfolded, sources indicated Zoph was in contact with executives from Meta Superintelligence Labs prior to his departure from Thinking Machines. He eventually secured a position with OpenAI, a move that OpenAI’s applications CEO, Fidji Simo, claims had been developing for several weeks. Simo expressed confidence in Zoph’s ethics, dismissing concerns raised by Thinking Machines’ team.

This week marked a significant shift at Thinking Machines, as Luke Metz, another cofounder, along with at least three researchers made their way to OpenAI. This follows the earlier departure of another cofounder, Andrew Tulloch, who left to join Meta in October. The exits have raised questions about the startup’s internal dynamics and the decision-making processes that have contributed to the wave of resignations.

Reports indicate that disagreements regarding the company’s direction and product development strategies may have fueled dissatisfaction among employees, leading to the recent departures. Despite being in discussions to secure funding at a staggering $50 billion valuation, up from its current value of $12 billion, the internal discord may overshadow such financial ambitions.

Sources have confirmed that the leadership at Thinking Machines did not respond to queries regarding the employee exits or the allegations involving Zoph. The mounting tensions and subsequent resignations cast a spotlight on challenges within startups as they navigate rapid growth and shifting priorities.

As the landscape evolves, the impact of these changes on Thinking Machines Lab’s future remains to be seen, particularly in a climate where talent acquisition is critical to a company’s success. The ongoing situation raises broader questions about workplace culture, ethical standards, and the complexities of high-stakes technology development in the competitive tech industry.
