Building what it calls an “artificial general engineer”: AI aimed at designing and manufacturing physical things rather than writing text, with stated targets including jet engines, cars and drug compounds. The premise is that models for the physical world have to learn from real-world trial and error, not only from data scraped off the internet.

PrePost's proprietary index, combining capital-raising momentum, market-pricing confidence, and investor strength into one comparable score from 0 to 100. It lets you compare companies on those three measures; it is not a rating of the investment. How it works
Read how this company is being sold before reading its valuation. A search of SEC Form D filings for “Prometheus” returns 57 distinct filers, and Prometheus is not one of them. About thirty of the fifty-seven are special purpose vehicles whose business is selling access to it, including four monthly vintages of a single serial platform — Project Prometheus Apr 2026, May 2026, Jun 2026 and Aug 2026 — alongside DV Project Prometheus SPV I, MW VC Prometheus and MW VC Prometheus-II, Dominari Master SPV LLC Series XXIV Prometheus, D. Boral Master SPV LLC Series X Prometheus, and Moringa x Prometheus LLC. So an individual offered “Prometheus shares” is very unlikely to be offered shares in Prometheus. The likely offer is units in one of about thirty vehicles that hold some, each taking its own fees and carry, and each a claim on a vehicle rather than on the company. Ask which entity is issuing what you are buying, and what it charges. The name is a trap too. Roughly ten unrelated companies file under it: Prometheus Biosciences, Prometheus Fuels, Prometheus Materials, Prometheus Labs, Prometheus Therapeutics, Prometheus Energy Group, Prometheus Hyperscale, Prometheus Springs and Prometheus Franchise Restaurant Holdings among them. A document naming “Prometheus” proves nothing on its own. On the figure itself: $41bn is press-reported, not filed, and not marked by any fund on this site. Bloomberg reported the same round closing at $38bn seven weeks earlier. For a company founded in November 2025 with about 150 employees and no reported revenue, the valuation rests on who is backing it rather than on anything that can be checked.
No notable non-founder leadership on record for Prometheus yet.
Low: New York Times, December 2025 reporting: “over 120 employees”, including researchers hired from xAI, Meta, OpenAI and DeepMind.. High: Reported as “about 150 people” in coverage of the June 2026 round, read 2026-09-20..

| Notes | None. The company is ten months old, has raised more than $18bn across two rounds and has no reported revenue. Nothing about it suggests a listing is near, and the presence of JPMorgan, Goldman Sachs and BlackRock on the cap table should not be read as one: they invested, which is a different thing from underwriting. |
