Jeff Bezos-led AI startup Prometheus is reported to have raised $12 billion in a Series B funding round that values the company at $41 billion. Multiple outlets say the startup launched in November and is focused on AI tools intended to help engineers design and streamline the development of complex physical products, including items such as jet engines and medical devices.
One report describes Prometheus as being co-led by Bezos and Vikram Bajaj, a former Google executive. The fundraising is framed as part of the broader AI boom and as reinforcing Bezos’s role in the sector.
Investors mentioned across coverage include large financial and investment firms such as JPMorgan Chase, Goldman Sachs, BlackRock, DST Global, and Arch Venture Partners, along with Bezos participating personally. The Next Web also reports that total funding for Prometheus now exceeds $18 billion.
Sources agree on the key figures—$12 billion raised and a $41 billion valuation—and on the company’s product-building focus for engineering workflows, particularly for hardware and other regulated or intricate manufacturing contexts.
