MINNEAPOLIS, Minn. — October 27, 2025 — Groove Capital announced that it has added Maxwell Labs, a St. Paul–based startup pioneering laser cooling technology for AI hardware and high-performance computing (HPC) systems, to its investment portfolio.
Earlier this year, in June 2025, Maxwell Labs received a $500,000 award through the Basic Energy Science to St. Thomas Applied Renewable Technologies (BEST START) program — a collaboration among the U.S. Army Combat Capabilities Development Command Army Research Laboratory (DEVCOM ARL), the University of St. Thomas (UST), and the Energetics Technology Center (ETC). The funding supports the company’s development of energy-efficient thermal management solutions for military and commercial computing systems.
Maxwell Labs’ patented solid-state laser cooling system converts heat into light at the chip level, overcoming the limitations of traditional air and liquid cooling. The technology is designed to enhance compute density, energy efficiency, and reliability across applications such as defense systems, AI data centers, edge computing, and aerospace hardware.
Through the BEST START program, Maxwell Labs collaborates with the University of St. Thomas School of Engineering, leveraging facilities like the Center for Advanced Manufacturing and the Center for Microgrid Research. The partnership also provides opportunities for UST students to gain hands-on experience in fiber laser technology, optical sensing, and thermal modeling.
