Founded in May 2025, LayerPure Technologies LLC develops ultra-thin, anti-fouling membranes for high-rejection water treatment. Its membranes reach steady-state performance within 30 minutes and deliver more than 93% boron rejection in a single pass without pH adjustment. The company’s team brings more than 25 years of combined experience in membrane science and technology, while its early work has earned recognition in university pitch, venture, and technology-maturation competitions.
Bettergy CorpFounded in 2008, Bettergy Corp. develops and commercializes energy and environmental technologies built around nanopore-engineered membranes. The company began as an energy-storage technology venture studying membrane advances and now applies that expertise to green hydrogen from ammonia, gas separation, water purification, and electrochemical energy systems. Its work has been supported by federal agencies including ARPA-E, the Department of Energy, NASA, and the U.S. Navy, alongside university collaborations with institutions such as the University at Buffalo and Virginia Tech.PEEKSKILL, NY
King Lee TechnologiesSince Craig Netwig founded it in 1977, King Lee Technologies has built its identity around specialized reverse-osmosis chemistry and more than 45 years of close work with system operators, OEMs, and consulting engineers.
