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.
