Moleaer Inc.
Moleaer is a California-based cleantech company that pioneered the industrial-scale production of nanobubbles - gas bubbles roughly 2,500 times smaller than a grain of salt. Its patented nanobubble generators inject oxygen and other gases into water with extreme efficiency, helping farms, fish operations, wastewater plants, lakes and industrial sites use less water, fewer chemicals and less energy. Founded in 2016 and led by CEO Nick Dyner, Moleaer has deployed thousands of systems across more than 55 countries and raised about $61 million through a 2022 Series C led by Apollo funds, followed by a 2025 global partnership and strategic investment from water-tech giant Xylem.
