Jeff Bezos co-leads the AI startup Prometheus, which has raised $12 billion in a funding round that values the company at about $41 billion, according to multiple reports. The round is described as a Series B, and it comes shortly after Prometheus launches in November. Prometheus focuses on “industrial” or engineering AI tools intended to help streamline the design and development of complex physical products such as jet engines and medical devices. Several outlets describe the company as building systems that assist engineers in engineering and manufacturing workflows.

Prometheus is co-led by Bezos and former Google executive Vikram Bajaj. Reports also say the company has hired roughly 150 people. One outlet adds that investors in the round include JPMorgan Chase, Goldman Sachs, BlackRock, DST Global, Arch Venture Partners, and Bezos. Another outlet reports that total funding for the company now exceeds $18 billion, although figures beyond the $12 billion round are presented as cumulative. The reports characterize the fundraising as part of a broader AI funding boom and as reinforcing Bezos’ presence in the sector.
