What H3X Technologies does

H3X Technologies Inc. is a privately held US corporation founded in 2020 and headquartered in Louisville, Colorado. The company designs and manufactures high power-density integrated motor drives (IMDs) that combine electric motors with co-optimized power electronics in a single unit, achieving up to 12 kW/kg continuous power density — a level the company characterizes as the highest in its class. Its product portfolio spans the HPDM series (30 kW, 90 kW, 140 kW, 180 kW, 350 kW, and 500 kW stackable units) and the HPDG-30 hybrid genset, with megawatt-class systems under development. Core technology is built on proprietary electromagnetic designs, native HVDC output, motor-generator dual functionality, and fault-tolerant multisector architecture for graceful degradation.

H3X serves four primary end markets: aerospace (electric and hybrid aircraft, eVTOL, airships, space vehicles), defense (UAS, hypersonic, undersea AUVs, submarines, mobile power), marine (hybrid-electric ships, workboats, racing yachts, USVs), and heavy industry (mining vehicles, e-fracing, industrial heat pumps, MW-class power generation). Named customers include NASA, the United States Air Force and AFRL, Lockheed Martin, Hermeus, SailGP, and Stralis, with 12 customers overall including three defense primes.

The company operates a direct, sales-led B2B go-to-market targeting defense primes, aerospace OEMs, and industrial customers. Revenue derives from hardware sales of IMDs and hybrid power systems, supplemented by government R&D contracts (NASA SBIR phases, USAF TACFI, AFWERX Phase II). Pricing is custom and quote-based, with no public price list. Capital structure reflects venture and strategic backing — $3.8M seed in 2021 led by Metaplanet, with subsequent AFWERX and NASA grants, Lockheed Martin Ventures investing in February 2023, and a $20M oversubscribed Series A in August 2024 led by Infinite Capital with broad institutional participation.
