Matt Loszak is CEO and co-founder of Aalo Atomics, a startup designing 50-megawatt nuclear power plants made of pods of five 10-megawatt reactors each, targeting the data center market.

Inspired by the MARVEL test reactor that his CTO Yasir Arafat led at Idaho National Lab, Aalo pursues parallel DOE and NRC pathways, betting that factory-built, pad-ready nuclear plants can slash cost, schedule, and grid-interconnection delays. Now 45 teammates strong and raising a Series B, Aalo aims to break ground on its first plant within 12 months and go critical the year after, powering the AI era with compact, clean, always-on fission.
