Mass Magnetics
Founders
Mass Magnetics turns recycled rare-earth scrap into high-performance, DFARS-compliant permanent magnets made in America. The company uses vertically-integrated, AI-enabled supply chains to recover critical metals from post-consumer hardware streams, bypassing the capital intensity and permitting delays of traditional mining. Its magnets serve as the backbone materials for electric motors, sensors, robotics actuators, and defense electronics, targeting manufacturers who require a domestic, China-independent supply. Backed by Y Combinator (S26), Mass Magnetics operates out of Greentown Labs in Greater Boston, MA and Columbus, IN.
