A new and highly secretive AI startup, Project Prometheus, is quietly emerging as one of the most ambitious bets in the artificial intelligence race. Backed by Amazon founder Jeff Bezos and co-led by former Google executive Vikram Bajaj, the company was founded in 2025 with a bold goal: to take AI beyond chatbots and into the physical world.

Unlike tools such as ChatGPT or Claude Code, Prometheus is focused on building systems that understand real-world environments. Its AI models are being designed to work in industries like aviation, engineering, and architecture, using domain-specific data such as jet engine design.

A major boost to the company comes from the hiring of Kyle Kosic, a co-founder of xAI. Kosic, who previously worked with Elon Musk and helped build the Colossus supercomputer, will now lead Prometheus’ AI infrastructure efforts.

The startup is also part of a growing “talent war” in AI, where top engineers are being aggressively recruited with massive offers. Notably, all 11 co-founders of xAI have now exited, highlighting rising tensions in the industry.

Prometheus is expanding fast, with offices in San Francisco, London, and Zurich, and hundreds of employees already hired. Its long-term plan includes raising tens of billions of dollars and building a Berkshire Hathaway-style investment model, acquiring stakes in companies, and using their data to train smarter AI.

Despite its rapid growth, Prometheus remains highly secretive, with no official public statements yet.
