AI Founder Mira Murati: The Difficult Life After Open AI

Summary

Mira Murati, the former Chief Technology Officer of Open AI, founded the AI startup Thinking Machines Lab in February 2025 and raised two billion dollars. However, less than a year later, the company is struggling with massive internal turbulence: several co-founders have returned to Open AI, investors are hesitant about further financing, and the business model remains vague. The ability of startups to retain top talent against tech giants like Meta and Google proves to be a decisive challenge.

Detailed Summary

Rise and dramatic turn at Open AI

Mira Murati was born in Albania in 1988 and left her home country at age 16 on a scholarship to Canada. After studying mathematics and mechanical engineering, she worked at Tesla as a product manager for the Model X before joining Open AI in 2018. There, she initially served as Vice President for AI Applications, and from spring 2022 as Chief Technology Officer. She shaped the phase in which Open AI released ChatGPT in September 2023 – a turning point for the entire AI industry.

In November 2023, an internal conflict escalated: the board fired co-founder and CEO Sam Altman, claiming he had not been "consistently truthful." Murati was temporarily appointed as his successor, but at the same time publicly advocated for Altman's return. Internal reports suggest that she had herself previously criticized Altman's leadership style to the board. After a few days, Altman was reinstated; Murati returned to the second tier, but remained one of the most prominent faces in the AI scene.

Founding and rapid decline of Thinking Machines

After about a year, Murati left Open AI and founded Thinking Machines Lab in February 2025. The company positions itself not as a developer of large AI models, but as a provider of tools for fine-tuning existing systems for specific industries and tasks. In July 2025, she raised two billion dollars in the first financing round from prominent investors such as Andreessen Horowitz, Nvidia, and Advanced Micro Devices. The valuation at the time was twelve billion dollars.

However, cracks quickly appeared. Several co-founders, including Barret Zoph, have returned to Open AI. According to media reports, Murati had stripped Zoph of responsibility after learning about a private relationship with a colleague and complained about his productivity. Tensions escalated, and after discussions about strategic direction, Zoph and two other employees resigned. Of the six-member founding team, only three remain active – a dramatic personnel loss for a young company.

Structural problems and the war for talent

The departures reflect a fundamental problem in the AI industry: startups cannot compete with the salary offers of tech giants. Mark Zuckerberg has aggressively recruited AI talent, sometimes with annual salaries in the hundreds of millions. In fall 2025, Meta recruited Andrew Tulloch, another co-founder of Thinking Machines. A similar fate befell Ilya Sutskever, who founded his own startup Safe Superintelligence with co-founder Daniel Gross – he too was poached by Meta.

Additionally, established AI companies like Open AI and Anthropic compete with the promise of IPO and stock options, which could mean potentially significant wealth gains.

Investor skepticism and uncertain business model

Thinking Machines launched its first product Tinker in October 2025 – an interface for fine-tuning AI systems. However, the specific business model remains vague. Investors are hesitant about further financing: a planned financing round is reportedly aimed at a 50 billion dollar valuation, but the New York Times reported resistance. Some funders question whether Thinking Machines has a future as an independent company at all. Meta is said to have even made a takeover offer to the company, which was rejected.

Key Findings

• Talent drain is the central problem: Not technical challenges, but competition with tech giants for AI specialists threatens Thinking Machines.
• Internal conflicts under pressure: Personnel issues like the conflict with Barret Zoph point to leadership challenges under extreme pressure.
• Business model unclear: Despite high valuation, revenue potential and market position remain unclear.
• Investor skepticism grows: The planned Series B round is expected to be valued at 50 billion dollars, but investors doubt long-term viability.
• Structural industry problem: The experience of Thinking Machines reveals a systemic problem for young AI startups in competition against established players.

Stakeholders & Affected Parties

Opportunities & Risks

Action Relevance

For decision-makers and investors:

1. Concretize business model: Thinking Machines must transparently communicate how Tinker is monetized and what market size is realistic.

2. Reconsider retention strategy: Salary alone is not enough – equity plans with clear IPO pathway or strategic partnerships could be more attractive.

3. Stabilize organizational structure: Leadership challenges (such as the Zoph conflict) must be resolved transparently to maintain trust.

4. Understand industry dynamics: AI sector startups must be aware that tech giants systematically poach their best talent – strategic alliances could be a way out.

5. Flexibilize Series B strategy: A 50 billion dollar valuation may be unrealistic; a lower but secure round could be strategically more sensible.
