Key metrics for this segment: key milestone. Figures as published by each company or the press, dated, not recalculated. The AIs weigh them alongside funding history and comparables.

Not in this segment. Listed, so not ranked: General Fusion (Nasdaq, Jul 2026), X-energy, newcleo, Deep Fission, Standard Nuclear, Hadron Energy, Terrestrial Energy, ONE Nuclear, Steady Energy, Fermi America, Oklo, NuScale, Nano Nuclear. TAE Technologies and Blue Laser Fusion leave the ranking once their pending listings close. Not eligible because created or owned by a group: Rolls-Royce SMR, Calogena (Groupe Gorgé), Holtec (established company). Kairos Power has disclosed no equity round. Insolvent: Naarea (taken over by Eneris), Moltex Energy. Chinese companies are never ranked: NovaFusionX, Startorus Fusion and Energy Singularity are among the best-funded fusion companies. A company appears in one segment only. Method

Invest in fusion & advanced nuclear, together

Uback aggregates investment intentions from business angels, family offices, corporates and sector specialists worldwide. Every ranked company already has professional investors on its cap table, who have negotiated a shareholders’ agreement: you don’t start from a blank page.

Strength in numbers

Alone, a small ticket opens no doors. Together, Backers carry weight.

Declare an intention

On a company, whether or not it has agreed, or on this segment, worldwide, in a region or in a country, with a ticket range. Paid, to show you are serious; valid for life, and movable until a deal process opens.

Critical mass is reached

When the pool’s combined amount reaches its critical mass, a floor amount estimated by the AI, the pool is passed to the local partner, who presents this demand to the companies concerned.

The local partner structures

If the company’s expectations and the Backers’ converge, the partner builds a transaction and presents it directly to the Backers concerned.

Closing

Capital raise or sale of existing shares: small tickets are pooled in a common vehicle set up by the local partner. Each Backer decides whether to take part.

Uback does not advise, does not negotiate, collects nothing. Each transaction is run by the local partner of the company’s country, under the law that governs its shares.
