# Prometheus Raises $12B Series B at $41B Valuation

> Prometheus, a startup backed by Jeff Bezos, has raised a $12 billion Series B at a $41 billion valuation, led by JPMorgan, BlackRock, Goldman Sachs, DST Global and Arch Venture Partners. Those are enormous numbers for a company founded only in late 2024, and they reflect an unusually ambitious goal: building what it calls an artificial general engineer, software meant to automate the design and manufacture of physically complex systems like jet engines, medical devices, consumer electronics and even drug compounds. The pitch is a deliberate departure from the chatbot-and-coding race. Where most frontier labs aim AI at language and software, Prometheus is aiming it at the physical world of engineering, a domain with slower feedback loops but potentially huge payoffs. Bezos was the largest backer of the Series A at $6.2 billion and joined this round too, and the company is co-led by Vik Bajaj, a Stanford professor and co-founder of Alphabet's Verily. It is early, unproven and richly funded in equal measure, but it represents one of the biggest bets yet that AI's next frontier is designing hardware, not just writing text.
