Starmaker One · Flagship Fund

Recreating the power of the stars

Starmaker One, East X Ventures' flagship fund, backs the teams making fusion power a commercial reality by investing across systems and supply chains.

Thesis & focus areas

We invest in companies across the full vertical

Systems — fusion-approach agnostic

The reactor, magnet, laser and plasma systems that turn fusion physics into deployable power — backing the strongest teams whatever their path to net energy.

Supply Chain — the enabling technologies of fusion & beyond

The enabling industrial base for fusion — components, materials and manufacturing that turn reactor designs into deployable systems.

Why fusion, why now

The hardest, highest-leverage problem in the energy transition is generating abundant clean power.

For decades fusion was a physics problem. That has changed. Superconducting magnets, high-energy lasers, advanced manufacturing and modern simulation have moved fusion from the lab toward the grid — and a generation of companies is now turning that physics into engineering.

Starmaker One exists to back those teams at the point where conviction matters most: early, when the science is proven but the company is still being built.
