Tides is comprised of five separate legal entities – Tides Network, Tides Center, Tides Foundation, Tides Two Rivers Fund and Tides Inc. Tides Network is the parent organization employing the majority of Tides staff and providing service to our various partners. Tides Two Rivers Fund and Tides Inc. operate our two Tides Converge centers in San Francisco and New York.

Tides Foundation serves as a grantmaking organization primarily through the management of close to 400 donor advised funds. Unlike other foundations, Tides Foundation does not have an endowment, and all grants are made on the recommendation of donor clients. The Foundation does not take unsolicited grant requests. Tides Center primarily offers fiscal sponsorship and nonprofit acceleration services. No preference is given to Tides Center social ventures by the Tides Foundation.
