A young company that formed during the pandemic and chose the Denver area as its base has big ambitions: to become the world’s leading supplier of advanced electric motors. The company, H3X, was founded by a team of engineers and has grown since its start in 2020 to 33 employees. “We’re aiming to get to 45 to 50 by end of the year,” said Jason Sylvestre, co-founder and CEO. The startup’s mission, Sylvestre said, is to help decarbonize the aviation, aerospace, marine, defense and heavy-industry sectors by designing and producing high-density, lightweight electric motors.
