Prometheus.
Kevin Wilson · Principal · New York
Jeff Bezos is building the artificial general engineer. This is your chance to own it before it's public.
Prometheus raised $12 billion at a $41 billion valuation in June 2026 — up from $6.2 billion at launch just seven months earlier. Singularity Ventures can place private shares with qualified individual investors.
AI for the physical economy.
Most AI writes text. Prometheus builds things. It applies artificial intelligence to the full arc of physical creation — design, prototyping, and manufacturing — treating it as one end-to-end problem. Bezos describes it as "a very, very modern version" of CAD software, aimed at compressing the slow, expensive path from idea to finished product.
An “artificial general engineer”
Software meant to design and help manufacture complex physical systems — from jet engines to drug compounds.
Not robotics, not factories
“Nothing to do with robotics.” The focus is pre-production — prototyping, optimization, and engineering workflows.
A dedicated, independent company
~150 people across San Francisco, London, and Zurich. No corporate ties to Amazon or Blue Origin.
Building physical things is still painfully slow.
A jet engine takes teams of engineers a decade or more to design, prototype, and manufacture — one of the most complex creative acts humans attempt. Bezos' pitch: build a set of tools that empower engineers to compress that cycle.
Physical AI is the next frontier — and the most defensible.
Investors argue physical AI is harder to copy than pure software — the real world creates moats that code alone cannot. Prometheus is aiming at the largest, slowest-moving industries on earth.

The most sophisticated capital in the world already said yes.
The window is open — for now.
Private is the only door
Bezos says an IPO is “too early to think about.” Until then, public investors simply cannot buy in — private placement is the only way to hold shares.
The valuation keeps stepping up
$6.2B at launch → $38B by April → $41B in June. Each round has repriced the company higher.
Capital-intensive by design
Enormous compute and proprietary training data raise the barrier to entry — and the scarcity of access.
What every investor should weigh honestly.
Pre-product. No public product yet and no disclosed launch timeline — only that “early rollouts are coming.”
Unproven training path. The company hasn't said how it trains; there is no “internet of manufacturing data” to ingest.
Capital-intensive. Compute and data costs are high; future rounds could dilute early holders.
Illiquid & speculative. Private stock can't be freely sold; you may hold for years, or lose the entire investment.
