Prometheus, the industrial AI startup led by Jeff Bezos and former Google exec Vik Bajaj, today will announce that it’s raised $12 billion in Series B funding at a $41 billion valuation. It’s a massive bet to rearchitect how physical things are made, from jet engines to medical devices to consumer electronics. “The cycle from dream, to manufacturing at rate, to having it out in the world can be very long,” Bezos tells Axios. “For example, if you go to a current jet engine manufacturer and say you want the exact same engine but with 10% more thrust, it could be a 10-year program. Not because they’re lazy or bad at their jobs, but because it’s so complex. So what we’re doing is building a set of tools that will empower engineers to compress that cycle time and make that dream-build loop be 10 times faster or even more.”
