Bezos raises $12B Series B for Prometheus, an industrial AI startup targeting 'artificial general engineer'

Bezos Backs $41B Industrial AI Play to Build 'Artificial General Engineer'

Jeff Bezos is co-leading Prometheus, a new AI startup valued at $41 billion, which just raised $12 billion in Series B funding from JPMorgan Chase, Goldman Sachs, and BlackRock alongside Bezos himself. The company, started in late 2024 with Vic Bajaj (a Google veteran and former healthcare founder), has 150 employees across San Francisco, London, and Zurich.

Prometheus aims to build what Bezos calls an "artificial general engineer"—AI systems that can design and manufacture complex physical products like jet engines. The company's scope spans the full engineering process: product design, performance prediction, and manufacturing instructions.

The $41 billion valuation sits in rarefied air. It exceeds AIG's market cap, Chipotle's, CBRE's, and Baidu's. To contextualize the fundraise itself: the $12 billion Series B represents a tenfold jump from what used to be typical venture stages. Where a Series A might have been $6 million and Series B $12 million, frontier AI now moves in billions.

The manufacturing angle matters. Bezos told the Journal he expects AI to create a labor shortage, not mass unemployment—a claim anchored in his belief that productivity gains will outpace job losses. His example: retail employment shrank as Amazon scaled, but the number of entrepreneurs selling on the platform and building around its ecosystem grew far larger. He suggested some households could shift to single-earner models if productivity surges enough, though he didn't claim this would show up as lower unemployment (since the unemployment rate only captures active job seekers).

The company discussed raising a $100 billion fund to acquire manufacturing businesses and deploy AI across their operations, though that plan did not materialize in this round. The stated goal with such capital would have been to buy established manufacturers—Goodyear was floated as an example—and optimize them with AI.

Bezos's co-CEO, Vic Bajaj, is an adjunct professor at Stanford School of Medicine and previously co-founded Google's life sciences division. Bezos brings deep robotics and AI experience from Amazon's recommender systems and Kiva Robotics, the acquisition widely regarded as one of the most successful in the robotics boom.

The company has shown demos of AI modeling complex designs—including Boeing 747 exteriors pulled from internet CAD files—and generating step-by-step manufacturing instructions. The inference is that the gap between AI-generated designs and manufacturable products is narrowing fast. For aerospace, where certification and scaling take decades even after designs are solid, a 10% speedup in the engineering cycle would save years.
