TechCrunch reports on this.
The company is developing an AI system to accelerate the design and manufacturing of physical objects—from jet engines to medical devices and consumer electronics. The founders call the future product a “universal AI engineer”: the system is designed to help speed up the journey from idea and prototype to mass production.
In an interview with Axios, Bezos used the example of a jet engine to explain that modifying the design to increase thrust by 10% can take years due to the complexity of manufacturing. Prometheus aims to reduce such cycles by a factor of 10 or more.
The startup emphasized that this is not about building robots or simply automating factories. Prometheus focuses on developing AI for the real economy and the early stages of manufacturing: design, modeling, prototyping, and process optimization.
Product details and the public launch date remain under wraps. According to Axios, the company does not disclose exactly how it trains its models, but acknowledges that there is no equivalent in the industry to an “industrial internet of things” that can simply be fed into a model.
10 employees instead of 100
“The cycle from idea to mass production and bringing a product to market can be very long,” Bezos noted.
He said that if a task that currently requires 100 engineers and 10 years can be accomplished by 10 engineers in just one year, “we’ll simply build a lot more things.” Bajaj, in turn, added that if it becomes easier to bring ideas to life, this will lead to more inventions and more people involved in the process.
According to Semafor, Prometheus uses data from the laws of physics, its own testing, and collaborations with companies. A significant portion of the funds raised will be directed toward computing power: the startup uses an internal cluster and purchases resources from third-party providers.
This was Prometheus’s second funding round—at the end of 2025, the startup raised $6.2 billion. Among the new investors, Axios and Semafor name JPMorgan, Goldman Sachs, BlackRock, DST Global, Arch Venture Partners, and Bezos himself.
