Thinking Machines Lab, the San Francisco-based AI startup founded by former OpenAI CTO Mira Murati, has lost two more founding members to Meta. The departures follow a pattern of recent exits by high-profile talent from the company to OpenAI, which raised $2 billion at a $12 billion valuation last year. The startup focuses on enabling developers to custom-build AI models and has been a target for recruitment by larger tech firms including Meta and OpenAI.
Key Founders Depart for Meta
Christian Gibson and Noah Shpak, previously listed as founding members on Thinking Machines Lab’s website, have joined Meta within the past few weeks, according to sources familiar with the matter. Gibson, a former OpenAI engineer, specializes in supercomputers for AI model training and contributed to the development of the first ChatGPT model. Shpak, an AI-focused engineer, previously worked at Character.AI and X.
The company has faced a string of high-profile departures over the past year. Co-founder Andrew Tulloch left for Meta last year, while CTO Barret Zoph and co-founder Luke Metz joined OpenAI last month. Other exits include Jolene Parish, a founding member specializing in security, along with two additional researchers.
Startup Continues to Attract Top Talent
Despite these departures, Thinking Machines Lab remains a hub for AI expertise. The company quietly hired Neal Wu, a programming Olympiad triple gold medalist, and Soumith Chintala, the creator of the open-source AI framework PyTorch, who now serves as the startup’s CTO. These hires reinforce the startup’s reputation for drawing elite AI engineers, even amid significant turnover.
The recent exodus underscores the competitive environment in AI talent acquisition, with major companies such as Meta and OpenAI actively recruiting experienced engineers and researchers. While Thinking Machines Lab continues its operations and maintains its development focus, the loss of multiple founding members raises questions about retention and the startup’s long-term stability in a rapidly evolving sector.
