Hudson Sustainable Group
Mission
We provide innovative leadership in enabling low-carbon energy adoption through expertise at the intersection of technology, policy, and markets.
Hudson was built for clean energy's structural moment.
In 2007, institutional capital didn’t know how to reach clean energy at scale. Neil Auerbach saw the gap: founders needed structuring partners who understood policy, markets, and capital markets simultaneously. Hudson was founded to close that gap—starting with America’s first solar fund.
