ENGtechnica found out about Project Prometheus in March when the stealthy San Francisco startup was sitting on roughly $9 billion in backing, at least some of it from Jeff Bezos. The company had a bold mission: to use world-model AI, AKA physical AI, to reinvent how engineers design and manufacture products.
In November 2025, the New York Times revealed not nearly enough about a stealthy Project Prometheus that was “coming out of the gates with $6.2 billion in funding.” Bloomberg reported today that Prometheus has closed a $10 billion funding round and the company is valued at $38 billion.
Since $10 billion makes Prometheus the biggest startup in the industrial AI space, and it’s backed by media magnet Jeff Bezos, its story has been picked up by all the financial press. That may have also rankled the hundreds of AI startups already in this space who can’t get any attention from the financial or popular press. In our ongoing Future of Design and Engineering Software podcast, in which AI startups have and will be featured, I expect to see brave faces and hear how Prometheus serves to validate the overall mission of bringing AI to the industry and that in this big ocean, there’s plenty of space for all fish, big and small. Words to that effect, anyway.
JPMorgan and BlackRock are now also investing in the round. They might appear to be riding Bezos’ coattails, but a person familiar with the situation insists to Bloomberg that there is no lead investor. We’re left clutching straws as little else has been disclosed. No investors are talking
Bezos has made himself co-founder and co-CEO alongside Vik Bajaj, formerly at Google, who presumably has more time to devote to the project. After all, Bezos has several projects underway, including Blue Origin, with which he competes with Elon Musk in the billionaire’s space race. Also, he is a newlywed, which all by itself could require a lot of his attention.
We would do well to remember that Bezos, although rich and famous from what is essentially a shopping service, is no technical slouch. He has a bachelor’s degree in electrical engineering and computer science from Princeton. Project Prometheus will be Bezos’s first operational role since stepping down as Amazon CEO in 2021.
No doubt, Project Promethius has and will have Vik Bajaj’s undivided attention. Bajaj has a PhD from MIT, though it is in physical chemistry, not computer science or engineering. He is an ex-Google X director and co-founder of both Verily (Google Life Sciences) and Foresite Labs, and was involved in Google’s moonshot projects, including the autonomous vehicle program that became Waymo.
The pair is said to have been flying around the world seeking funding, with Bezos supplying the vision and goals, and Bajaj supplying the details on how the vision and goals will be achieved. Known to be pitched were the sovereign wealth funds of the UAE and Singapore.
Prometheus has over 120 employees. With so much funding, the company can attract high-priced talent from major AI organizations, including OpenAI, xAI, Meta, and DeepMind.
Dollar figures with this many zeroes are bound to get the attention of the financial press. It may even appear to them that Prometheus hopes to revive manufacturing in America, though that would be based entirely on where Prometheus’ founders live.
The industry press is a little more guarded, even skeptical, of a startup, though well-heeled and well-intentioned, that is naively assuming it can provide answers in design and manufacturing. But that is the conceit of tech firms, that they and they alone can solve all the problems of the technical world, that which was once entrusted to engineers.
“Given the complexity of Revit modeling a single building, I suspect the complexity of our world is not particularly modelable,” says Ralph Grabowski, leading CAD journalist and degreed civil engineer.
Manufacturing is hard. So discovered another of the world’s richest men, Elon Musk, when running Tesla. Before Tesla turned profitable, it had to get automotive manufacturing right. It was not until the lower-cost, high-volume production of Model 3s started coming off the assembly line that the company turned the corner toward profitability. It’s a story well told by Walter Isaacson in Elon Musk.
The global AI-in-manufacturing market stood at roughly $34 billion in 2025 and is projected to reach $155 billion by 2030. While AI penetration across the $16.8 trillion global manufacturing sector remains below 1%. This difference is seen as huge potential by the thousands of startups that have sprung up. Investors eager to invest in the AI boom no doubt see manufacturing as a more serious, long-lasting and ultimately profitable category compared to other categories, such as social media, games, gambling apps and crypto.
Clearly, we need to watch this space. Not only is a lot of money coming in to invest, but also not just to Prometheus. NVIDIA’s deepening integration with Synopsys and Ansys, Autodesk’s $200 million stake in World Labs, and a wave of robotics and physical-AI startups all seemed to have reached the same conclusion: we need AI that understands the physical world.
