Overview
- Prometheus disclosed June 11 that it closed a $12 billion Series B that pushes the company’s valuation to roughly $41 billion and brings total disclosed funding above $18 billion.
- Co‑CEOs Jeff Bezos and Vik Bajaj say most new capital will buy massive compute capacity and generate the specialized physical‑world data needed to train what they call an “artificial general engineer.”
- The startup operates with about 120–150 staff across San Francisco, London and Zurich and has recruited researchers from OpenAI, DeepMind and Nvidia to build models for engineering, manufacturing and drug design.
- Prometheus denies formal corporate ties to Amazon or Blue Origin while leaving open commercial relationships, and the founders have not confirmed press reports that they plan a separate acquisition vehicle to buy industrial companies for training data.
- Analysts note physical AI needs bespoke experiments, real‑world tests and high simulation costs, which could create proprietary data moats but also raise safety, regulatory and trust questions before tools are used in safety‑critical industries.
