AI Story – Mira Murati: Rocketing From OpenAI CTO to AI’s Boldest Solo Act

When Mira Murati quietly stepped down as OpenAI’s CTO in September 2024, industry insiders expected her to resurface at another tech titan or maybe take a sabbatical. Instead, she spent three months assembling what would become Thinking Machines Lab, the fastest-growing AI company ever.

From the first lines of code in February 2025, the company operated in stealth, focusing on automating R&D workflows for large enterprises using AI agents not just to generate code, but to originate, test, and validate radical new ideas in engineering, manufacturing, and biotech.

Her playbook: recruit top researchers burned out by “LLM race” hype, keep team size lean, and ship products that speed up real-world innovation, not just digital conversations.

What’s Thinking Machines Lab Doing?

  • Autonomous R&D: Proprietary AI models simulate and run experiments, helping Fortune 500 clients cut years off product cycles.

  • AI Super-Orchestration: Their platform stitches different models and APIs together; routing LLMs, vision, and planning modules to the most relevant use case, managed by a single interface.

  • Rapid Scale: After a $2B July 2025 seed round, the largest ever, Murati led TML to a $12B valuation by October, breaking every fundraising and growth metric in the sector. 

Why It Matters?

  • Speed rewrites the rules: Murati’s journey from zero to $12B took 8 months in a space where even “unicorns” used to take years.

  • AI for real-world breakthroughs: By going beyond text and image generation to automating scientific discovery, TML threatens to upend multiple industries at once.

  • Founder-driven trust: Dozens of OpenAI and DeepMind alumni followed Murati thanks to her vision, discipline, and reputation for shipping real impact.

Lessons for AI Founders

  • Don’t fear incumbents: Murati left OpenAI at its valuation peak to compete directly and won trust by focusing on industry pain, not hype cycles.

  • Move faster by staying smaller: TML kept a sub-80-person headcount until Series B, proving that smaller, focused teams can outship “AI giants.”

  • Platform, not point solution: Their edge is in how different models and workflows are orchestrated together, not just the next flashy model.

What to Watch?

  • Will Thinking Machines Lab become the go-to “AI engine” for science, or will incumbents catch up?

  • Can Murati’s engineering-led culture persist as the company scales past $12B?

  • With rumors of cross-industry partnerships (from pharma to aerospace), is TML on track for an IPO or “AI as utility” status?

With the fastest 0-to-$12B journey ever, Mira Murati’s new chapter isn’t just about scale but about building AI infrastructure for the scientific revolutions to come.
