THE COMPANY: 

H3X Technologies is a U.S.-based manufacturer of electric motors for sustainable aviation, marine, industrial, and defense applications. They have developed a family of integrated motor drives that can scale in power from 30kW to 30MW with power densities as high as 12 kW/kg and best-in-class efficiency. This high performance is enabled by novel scalable core technology and proprietary manufacturing processes for motor stacking, winding, and assembly. The design, manufacturing, and testing of their products is done in-house at their headquarters in Louisville, Colorado. 

 
H3X’s world-class team is composed of experts from Tesla, SpaceX, GE Aviation, and Siemens with deep knowledge in electric machines, power electronics, material science, control systems, and advanced manufacturing. H3X takes pride in their multidisciplinary approach, relentless dedication, high capital efficiency, and Skunkworks-style execution. 

 
H3X has raised over $30M with backing from top VC firms and strategic firms, including Lockheed Martin, Hanwha, Y Combinator, Cubit Capital, Metaplanet, TechNexus, and Liquid 2 Ventures. 

 
H3X is poised to become the world’s leading supplier of advanced electric motors by 2030 to drive deep decarbonization in aviation, marine, and heavy industrial applications and unlock next-generation electrified defense technology to strengthen national security.
