Pulsed power fusion generator development and manufacturing

Renewable Energy Power Generation San Leandro, CA 51–200 employees Founded 2019 Privately Held

Fuse is building a fusion energy system (Titan) with a heavy engineering and manufacturing focus—12 of 16 active hires are engineering roles, supported by CAD, simulation (GEANT4, SPICE, MATLAB), and laser-design work. The stack reveals a hardware-heavy operation: Altium Designer and SolidWorks for component design, GEANT4 for radiation transport modeling, and C++ for control systems. Active pain points around radiation safety compliance, production scaling, and non-conformance reduction suggest they're transitioning from prototype to pilot manufacturing.
