01 About

Brian Riordan is the Co-Founder and COO of Avalanche Energy, building micro-fusion reactors (Orbitron) that are free of high-powered magnets or lasers and designed to be manufacturable and transportable. Brian and co-founder Robin Langtry met at Blue Origin, where both worked on rocket propulsion systems. Brian started his career in deep subsea oil and gas, pivoting to aerospace with side hustles along the way. Motivated by climate change and receding glaciers in his home state of Alaska, Avalanche has raised $45M+ and focuses on mobile power for space and underwater applications.
