What Zephyr Fusion does
Zephyr Fusion is building the first in-orbit fusion power source: a megawatt-class reactor enabling large-scale industry in space, at a fraction of the cost of equivalent solar. Founded by former physicists from Lawrence Livermore and Oak Ridge National Laboratories, Zephyr leverages decades of fusion research to deliver a compact magnetic confinement system designed to take advantage of the space environment.

Company
Zephyr Fusion
Powering tomorrow's industrial revolution in space
We are building the first megawatt-class fusion reactor designed to operate in orbit. Our product generates large-scale power cheaply in space, enabling industries like manufacturing and mining that need reliable energy beyond solar.
We live in San Diego, California and plan to keep the company based here after YC.
San Diego has a strong aerospace and defense ecosystem and access to fusion research talent, which fits our background and product well.
