Howard Yuh is a plasma physicist turned founder who is trying to break China's grip on magnesium by pulling the metal out of the ocean. As CEO and cofounder of Tidal Metals, the New Jersey deeptech he spun out of his earlier desalination venture GreenBlu, he uses an adsorption temperature-swing vapor pump - a trick borrowed from fusion research - to extract magnesium salt from seawater with only electricity, no mining, and no waste. The company raised $8.5M in seed funding led by DCVC in 2024 and won the World Economic Forum's Sustainable Mining Challenge the same year.
Gradiant is an MIT spinout turned global water-technology company that designs, builds, and operates advanced systems to treat, reuse, and recover industrial water and wastewater. Using a stack of proprietary technologies - from Carrier Gas Extraction to Counterflow Reverse Osmosis and an AI control layer called SmartOps - Gradiant helps semiconductor fabs, food and beverage giants, pharmaceutical makers, miners, and refiners cut freshwater use, recover lithium and other minerals, and destroy 'forever chemicals.' The first unicorn in the water industry, it reached a $2 billion valuation in 2026.
Ethan Cohen-Cole is the CEO and Co-Founder of Capture6, a Berkeley-based climate technology Public Benefit Corporation that has cracked one of cleantech's most stubborn puzzles: making carbon removal pay for itself. By integrating direct air capture with desalination brine management, Capture6 turns the costly waste stream of water treatment into a revenue engine - producing fresh water, green chemicals, and permanent CO2 sequestration simultaneously. Before pivoting to climate tech, Cohen-Cole spent 25+ years as a PhD economist, Federal Reserve bank regulator, and finance professor, giving him an unusually rigorous lens on the economics of decarbonization. Capture6 raised a $27.5M Series A in March 2025, backed by Hyundai's ZER01NE Ventures and Tetrad Corporation, bringing total funding to nearly $49M.
