Jeff Bezos’s industrial AI startup Prometheus announced a $12 billion Series B funding round at a $41 billion valuation, with participation from JPMorgan, BlackRock, Goldman Sachs, DST Global, and Arch Venture Partners, and Bezos himself. The company, which launched in November 2025 with $6.2 billion, is building an “artificial general engineer” to transform physical product design and manufacturing.
What is Prometheus building?
The “invention loop” is broken. Bezos gave a concrete example: “If you go to a current jet engine manufacturer and say you want the exact same engine, but with 10 percent more thrust, it could be a 10-year program. Not because they’re lazy, but because it’s so complex.”
Prometheus aims to build artificial intelligence (AI) tools that compress that cycle to be “10 times faster or even more.” The company claims that this is not robotics or factory automation. Bezos was explicit that Prometheus is not building robots. Instead, it’s a “very, very modern version” of computer-aided design (CAD), using AI to optimize pre-production machinery, prototyping, and engineering workflows.
Co-CEO Vik Bajaj, a Stanford professor and former co-founder of Alphabet’s Verily, points out that the pace of physical creation is “nowhere near the pace of human imagination.” The goal? If Prometheus succeeds, it will help engineers design, test, and build way faster, without leaving the digital world.
Why the massive valuation?
With a $41 billion price tag, Prometheus is already one of the priciest AI startups out there. Investors are betting big on “physical AI” because they see it as a safer, more defensible play than just software; it’s much harder to replicate, thanks to real-world data and deep manufacturing expertise, rather than just competing on chatbot features.
To make it happen, they’ve pulled together a powerhouse team of 150 pros across San Francisco, London, and Zurich, from places like OpenAI, DeepMind, and Nvidia. Bezos says most of the funding is going straight into the massive computing power they need to build this.
The funding will primarily go toward compute: “What we’re doing is very compute intensive,” Bezos commented. The company also clarified that it has no corporate ties to Amazon or Blue Origin, though Bezos called Blue Origin a “case study for a customer of Prometheus.”
Bezos on jobs, regulation, and secrecy
In his first extensive interview about Prometheus, Bezos addressed several hot-button topics. On AI and jobs, he disagrees with doomers. “Significant productivity in the economy is going to raise the standard of living,” he said. He predicted that many two-earner households could become one-earner households as productivity gains reduce the need for overtime.
On regulation: he called for “reasonable” rules that target applications, not foundational technology. “You don’t want to accidentally outlaw the knife because it can be used in a bad way.”
On Prometheus’s secrecy: Bezos pushed back, saying, “We’re not being secretive, we’re just being heads down.” But he acknowledged that “when you raise this much money, people do get curious.”
