# Prometheus raises $12B Series B at $41B valuation led by Bezos

> Prometheus, the secretive startup co-founded and co-led by Jeff Bezos and scientist Vik Bajaj, has raised a $12 billion Series B at a $41 billion valuation, an eye-watering sum for a company with only around 150 employees. The round drew a who's who of finance, including JPMorgan, BlackRock, Goldman Sachs, DST Global, and Arch, and follows a Series A that Bezos himself led at a $6.2 billion valuation. The company's mission is unusually ambitious: build what it calls an 'artificial general engineer' that compresses the long, expensive journey from design to manufacturing for physical products. Bajaj has framed the targets in terms of things with brutally slow development cycles, like jet engines that take a decade to design, along with bridges and semiconductors. The scale of the raise reflects how capital-intensive that vision is, demanding vast compute and specialized training data drawn from the physical world rather than the open internet. It also underscores a broader bet in Silicon Valley that the next frontier for AI is not chat or code but the atoms-heavy world of engineering and manufacturing, where progress has been stubbornly slow.
