We are a 317-person bet that the grid as you know it doesn't survive the 2030s — and that whoever builds what comes after writes the next century. We took the bet in 2019. We're winning it.
Fossil fuels won the 20th century because they were cheap, dense, and dispatchable. Renewables are cheap and clean, but they aren't dispatchable — and storage doesn't fix that at scale. Fission is dispatchable and clean, but politically radioactive and slow to build.
Fusion is all of the above. Cheap. Clean. Dispatchable. Buildable. The physics has been done for thirty years. What was missing was the engineering. We are the engineering.
We don't pitch fusion as salvation. We pitch it as economics. At $31/MWh unsubsidised, every other source on the curve becomes a legacy asset on a depreciation schedule.
Three founders. Twenty-eight years of plasma physics, magnet engineering and grid trading between them. Plus the rest of the bench. /team.
Plasma physicist (PhD MIT '13, post-doc Caltech '13–'19). Previously principal investigator on the SPARC tokamak collaboration. Author of 47 peer-reviewed papers on tokamak confinement. Holds patents on the high-temperature superconducting magnet topology used in Helios-1.
Mechanical engineer, ex-SpaceX (Raptor cycle, 2014–'18), ex-Commonwealth Fusion (lead structural, 2018–'19). Runs the entire reactor build programme. Has personally welded the inner vessel of Helios-Prime. Famously distrusts CAD that he hasn't drawn himself.
Twelve years on the ERCOT trading floor. Built the dispatch layer that became Grid-X. Has cleared more megawatt-hours into the Texas market than most utilities. Originally joined to write the term sheet; refused to leave.
“We are deeply uninterested in being the energy company you've heard of. We are interested in being the energy company you can't get away from.”
From a benchtop magnet rig to net-positive plasma in 73 months. The next 60 months take us to commercial.
