About Helion

We are a fusion power company based in Everett, WA, with the mission to build the world’s first fusion power plant, enabling a future with unlimited clean electricity.

Since Helion’s founding in 2013, we have raised over $1 billion from long‑time investors such as Sam Altman, Mithril, and Capricorn Investment Group, as well as new investors Soft Bank and Lightspeed.

Our last prototype, Trenta, completed 10,000 high‑power pulses and reached plasma temperatures of 100 million degrees Celsius (9 keV). We are now operating Polaris, our next prototype on the path to the world’s first fusion power plant.
