Murati's TML Secures $2B Seed, Soars to $10B Valuation for Enterprise AI

In a move that underscores the feverish investment climate surrounding artificial intelligence, Thinking Machines Lab (TML), the nascent startup founded by former OpenAI Chief Technology Officer Mira Murati, has secured a staggering $2 billion in seed funding.[1][2][3] This landmark financing round, one of the largest of its kind in Silicon Valley history, values the five-month-old company at an eye-watering $10 billion, despite it having no public product or revenue stream.[3][4] The funding frenzy, led by venture capital giant Andreessen Horowitz with participation from Conviction Partners, highlights a growing trend of investors betting heavily on the pedigree of founders from established AI labs, signaling immense confidence in Murati and her handpicked team of top-tier talent.[1][2][3]

The core of TML's ambitious strategy lies in a concept dubbed "RL for Business," or Reinforcement Learning for Business.[5][6] The company plans to move beyond generalized AI models and instead focus on developing highly customized AI solutions for enterprise clients.[5][6] This approach will use reinforcement learning—a method of training AI through rewards and penalties—to align the models directly with a company's specific key performance indicators (KPIs), such as revenue growth or profit margins.[5] By directly linking the AI's performance to tangible business outcomes, TML aims to provide a more targeted and valuable service than a one-size-fits-all chatbot.[7][8] This bespoke strategy is expected to give TML a competitive edge in specialized sectors like customer support, investment banking, and retail, where companies may be willing to pay a premium for tailored solutions that address niche market demands.[5]

To accelerate its go-to-market strategy, TML is not starting from scratch. Murati has indicated to investors that the company will leverage existing high-performance open-source AI models.[7][8] The plan involves a technique akin to "model merging," where specific layers or components from different open-source models are combined to create new, specialized systems without the time and resource-intensive process of training a massive foundational model from the ground up.[5][6] This efficient approach is designed to help TML rapidly develop and deploy products capable of competing with established closed-source models.[5] While the company's primary focus is on the enterprise market, there have been indications that TML is also exploring consumer-facing products, with some sources suggesting a potential competitor to OpenAI's ChatGPT was considered.[5][6]

The immense valuation and successful funding round are a testament to the all-star team Murati has assembled.[7] TML has become a magnet for top talent, attracting more than two dozen elite researchers and engineers from leading AI firms like OpenAI, Anthropic, and Meta.[1][5] A significant portion of the team, nearly two-thirds, are former OpenAI employees.[1] Perhaps the most notable hire is John Schulman, a co-founder of OpenAI and a leading expert in reinforcement learning who was instrumental in developing the technology behind ChatGPT. Schulman joins TML as a co-founder and chief scientist.[1][7] Other key figures include former OpenAI research vice president Barret Zoph and researcher Luke Metz.[1][7] This concentration of talent has not gone unnoticed by tech giants; both Meta's Mark Zuckerberg and Apple have reportedly held discussions with Murati about potential investments or acquisitions, though no deals materialized.[5][7][8]

The launch of Thinking Machines Lab and its record-breaking seed round signal a new phase in the AI industry's evolution. It represents a broader trend of highly-valued startups spinning out of established AI leaders, such as Anthropic, co-founded by former OpenAI VP of research Dario Amodei, and Safe Superintelligence, started by OpenAI's former chief scientist Ilya Sutskever.[1] TML's focus on customized, business-oriented reinforcement learning applications could carve out a significant new market segment.[5] While the strategy of building bespoke models for enterprises presents challenges in terms of scalability and profit margins compared to mass-market software, the sheer talent and capital at TML's disposal make it a formidable new player.[5] As the company begins to deploy its massive war chest and rents large-scale computing power from providers like Google Cloud, the AI world will be watching closely to see if this colossal bet on "RL for Business" can deliver on its transformative promise.[5][7]
