Infinitum
Infinitum is an Austin, Texas company reinventing the electric motor. Founded in 2016 by Ben Schuler, it replaced the century-old iron-and-copper stator with a printed circuit board (PCB) stator, producing air core motors that are roughly 50% smaller and lighter, use 66% less copper, and consume about 10% less energy than conventional motors. Its Aircore EC motor system integrates a variable frequency drive and targets HVAC fans and pumps, data center cooling, industrial equipment, power generation and mobility. Backed by more than $385M in funding and partners such as Rockwell Automation, Infinitum was named to Fast Company's 2025 list of the World's 50 Most Innovative Companies, ranking No. 1 in energy.
VEIR
VEIR is a Woburn, Massachusetts company commercializing high-temperature superconducting power lines that move 5 to 10 times more electricity than conventional cables at the same voltage and footprint. Its key breakthrough is a passive, evaporative liquid-nitrogen cooling system that keeps superconductors cold without heavy machinery. Founded in 2019 out of Breakthrough Energy Ventures research, VEIR targets utilities, renewable developers, and increasingly the power-hungry AI data center market. It closed a $75M Series B in January 2025 led by Munich Re Ventures, with backing from Microsoft's Climate Innovation Fund.
