Critical Loop
Critical Loop is an industrial power company founded in 2023 by former SpaceX, Tesla and Palantir engineers. It deploys modular, relocatable battery-storage microgrids - paired with its software-defined controller, Cygnus - to give factories, data centers, airports and other grid-constrained sites reliable power in weeks instead of waiting years for utility upgrades. The company raised a $26M Series A in April 2026, bringing total committed funding to $49M, and operates a fleet of control nodes across California.
