Together with our partners, we are harnessing society’s collective capacity to solve our toughest problems — from the existential threat of climate change, to persistent and pervasive inequities, to attacks on democracy itself. A nonpartisan philanthropy, the Hewlett Foundation has made grants in the U.S. and globally for nearly six decades based on an approach that emphasizes long-term support, collaboration, and trust.
