Cambridge Heavy Industries (CHI) – based in Cambridge, Massachusetts – is a fusion technology company developing compact inertial confinement fusion systems and fusion-enabling industrial infrastructure. The company operates within the ecosystem around Massachusetts Institute of Technology and The Engine, and positions itself less as a conventional utility-scale fusion developer and more as a company building industrial capabilities around fusion neutrons, tritium production, isotope generation, and high-energy-density systems.

Rather than pursuing long-duration, grid-scale fusion electricity, CHI is first focused on nearer-term commercial applications for fusion-derived neutron capability and fusion fuel-cycle infrastructure.
