# Steinmetz **Source:** https://geo.sig.ai/brands/steinmetz **Vertical:** IoT & Hardware **Subcategory:** General **Tier:** Emerging **Website:** steinmetz.com **Last Updated:** 2026-04-14 ## Summary EV power electronics startup with 3x power density motor controllers using SiC; 200kW peak through volume of 3 cans, targeting inverter supply as EV manufacturers move to wide-bandgap semiconductors. ## Company Overview Steinmetz is a power electronics company developing next-generation motor controllers and inverters for electric vehicles using silicon carbide (SiC) and wide-bandgap semiconductor technology to achieve dramatically higher power density than conventional EV power electronics — producing inverters with 3x greater power density than the state of the art while maintaining equal or greater efficiency, enabling EV systems that are smaller, lighter, and lower cost. Backed by investors including Y Combinator, Steinmetz's lead product is a motor controller that drives 200kW peak power through a volume equivalent to three yerba mate cans. Steinmetz's power density breakthrough addresses a fundamental EV cost and performance constraint: the inverter (which converts DC battery power to AC motor power) is one of the heaviest and most expensive components in an EV drivetrain. Heavier inverters reduce vehicle range (more weight = more energy to move). Larger inverters compete for space in increasingly compact EV platforms. Higher-cost inverters increase the bill of materials that EV manufacturers and tier-1 suppliers need to reduce to achieve price parity with ICE vehicles. Steinmetz's SiC-based architecture delivers the same power in a dramatically smaller form factor. In 2025, Steinmetz competes in the EV power electronics and inverter market with BorgWarner (NYSE: BWA), Vitesco Technologies (Schaeffler-acquired), Wolfspeed (NYSE: WOLF, SiC semiconductor leader), and STMicroelectronics (NYSE: STM) for EV motor controller and inverter supply. The EV power electronics market is growing rapidly as automakers electrify more vehicle models — the inverter market for EVs is projected to reach $20+ billion by 2030. SiC semiconductor inverters are the current technology frontier for high-efficiency EV drives, and the major EV manufacturers (Tesla uses SiC in Model 3/Y, BYD, GM) are all moving to SiC-based power electronics. YC's investment in a hardware startup in this space validates the technology differentiation. The 2025 strategy focuses on OEM qualification testing with EV manufacturers, demonstrating reliability in automotive-grade temperature and vibration conditions, and securing the development contracts that lead to production supply agreements. ## Frequently Asked Questions ### What does Steinmetz do?
