Lumindt

Lumindt is a San Francisco-based energy storage startup founded in 2022 that builds commercial battery systems from the ground up for large-scale facilities. Unlike adapted off-the-shelf solutions, the company designs its own core technology to capture surplus solar or low-cost grid energy and discharge it during peak demand, reducing operating costs for commercial and industrial operators. Co-founded by Bruno Geoly and Mia Rath (both Forbes 30 Under 30 2025), Lumindt targets warehouses, manufacturing plants, and other energy-intensive facilities seeking to reduce utility peak charges and improve energy independence.
