The Tides Foundation was founded in 1976 by Drummond Pike to work with “community-based nonprofit organizations and the progressive movement through innovative grantmaking.” It is a government sector lobbying organization, using grants from public and private sources to fund progressive charities and organizations.
Tides Foundation works with donors to increase and organize resources to incite "social change." It runs grant programs and promotes education.
Its self-identified progressive philanthropy provides a forum for grantmaking to non-profits and offers services to donors "committed to fairness, equality, and the sustainability of this world," its website says.
It is a public charity that structures individual philanthropies, linking them to a national and international network of like progressive charities and activist organizations.
