Stangenes Industries

What Stangenes Industries does

Stangenes Industries Inc. is a privately held, family-owned U.S. manufacturer of high-voltage pulsed-power systems and electromagnetic components, founded in 1974 in Palo Alto, California, and led since 2021 by second-generation President and CEO Lill Runge. The company designs and produces custom and standard high-voltage pulse modulators (solid-state Marx-generator topologies, including dedicated klystron, magnetron, and e-gun modulator product lines), pulse transformers (up to 1.5 MV and 6 kA), power supplies (10 kW to 2 MW capacitor-charging units), custom electromagnets (up to 40 T pulsed fields and 300 kA coils), current transformers, isolation transformers, voltage dividers (up to 800 kV), and tape-wound magnetic cores produced through wholly-owned subsidiary MK Magnetics in Adelanto, California. Technology differentiation rests on solid-state pulse-power architectures with patented parallel Marx generator topology, FPGA-based control, and proprietary access to nanocrystalline and amorphous magnetic materials.

The company sells primarily through an enterprise, direct, RFQ-based model with no disclosed standard pricing, multi-year custom contracts, and no distributor/reseller channel for core products. Revenue is generated from hardware sales to five primary verticals: Medical (radiation therapy and imaging OEMs), Military/Defense (NATO and DoD radar, missile guidance, air defense), Research (CERN, SLAC, Brookhaven, DESY, KEK and other national laboratories), Manufacturing/Industrial (semiconductor plasma control, laser cutting, sterilization), and Aerospace (avionics, navigation, communication transformers). The customer base of 50+ research institutions and multiple defense programs is served by a team of 125+ full-time employees averaging 15+ years of industry experience, with quality systems certified to ISO 9001:2015 and military specifications MIL-T-27 and MIL-I-45208. Stangenes competes on custom engineering depth, decades-long product lifecycles, and vertical integration into advanced magnetic materials rather than on volume or price.
