Thinking Machines Lab’s Focus and Funding
Murati’s startup, Thinking Machines Lab, was recently incorporated in Delaware as a benefit corporation, a structure that allows businesses to balance profit-making with social impact considerations. The company's name is speculated to be inspired by the intelligent “thinking machines” from Frank Herbert’s Dune or the defunct supercomputer company, Thinking Machines Corporation.
Reports suggest that Thinking Machines Lab is focused on developing Agentic AI—AI systems with autonomous decision-making capabilities. The startup has already secured over $100 million in funding, reflecting strong investor interest in its approach to AI development.
Schulman’s move marks another significant shift within the AI industry as former OpenAI executives and researchers pursue independent ventures in the rapidly evolving space.
