Bringing together people, ideas and resources, Tides actively promotes change toward a healthy and just society, one which is founded on the principles of social justice, broadly shared economic opportunity, a robust democratic process and a sustainable environment. Tides believes healthy societies rely fundamentally on respect for human rights, the vitality of communities, and a celebration of diversity.

Tides was established by Tides Foundation, Tides Center and Tides Shared Spaces to collaborate on programmatic strategies and operations. Tides strengthens the progressive movement through leading-edge thinking and technology, and efficient infrastructural services.

Each Tides founding organization pursues a distinct yet related strategy to promote the Tides mission. Tides Foundation works with donors to increase and organize resources for positive social change. Tides Center is sponsor to nearly 200 projects nationwide working to advance progressive social change. Tides Shared Spaces develops and manages sustainable workspace for nonprofits, providing space, community, and a NonprofitCenters model for the sector. The organizations collaborate as partners sharing ideas, technical systems and an office complex to increase their operational efficiencies. Tides appoints the Board members and CEO of all Tides organizations.
