In 1976, social entrepreneur Drummond Pike saw a need for more guidance in philanthropic giving. He founded Tides Foundation in response, creating an organization that is now one of the top social sector organizations in the United States. Tides has expanded its fields of expertise over more than four decades: nurturing new social innovations, convening advocates for justice, and bridging divides of all kinds in order to support forward-thinking nonprofit work.

To date, Tides has managed more than $3 billion in grantmaking and project-based activities, sponsored over 1400 nonprofit projects, and helped launch leading organizations like Environmental Working Group, the Story of Stuff, the Young Center for Immigrant Children’s Rights, and Social Venture Network. Alongside our global partners, we accelerate the path to social change, crafting bold solutions to the world’s most pressing challenges.
