# Thinking Machines Lab AI lab founded by former [[OpenAI]] CTO Mira Murati, which raised the largest seed round in history ($2B at a $12B valuation, July 2025) largely on team pedigree. A push to raise at $50B collapsed by January 2026, leaving it at its seed valuation with ~150 staff and two shipped products — a marker of where the AI capital market draws the line between frontier labs and the rest. > Status: stub — expand with Murati profile page, the OpenAI exodus roster, product direction (Tinker), and the failed $50B round as bubble evidence. ## See Also - [[AI Sector]] - [[OpenAI]]
