Tides Foundation

What Tides Foundation does

Tides Foundation is a 501(c)(3) nonprofit philanthropic organization founded in 1976 by Drummond Pike in San Francisco, operating as a network of five legally distinct but coordinated entities: Tides Network (the home office providing shared services), Tides Center (fiscal sponsorship), Tides Foundation (donor advised fund administration and grantmaking), Tides Two Rivers Fund (New York real estate), and Tides Inc. (San Francisco real estate). The organization manages $875M in assets across 400+ donor advised funds, 120+ active fiscally sponsored projects, and 8 themed collective action funds spanning climate justice, democracy, immigrant rights, health equity, gender justice, and crisis response. Tides reported reaching 4,000+ grantees in 2023 and has fiscally sponsored over 1,400 projects across its five-decade history.

The core business model combines fee-for-service managed services with recurring subscription-like revenue. Fiscal sponsorship under Tides Center's Model A charges 9% of project revenue (15% for government sources) for comprehensive back-office support including financial management, legal frameworks, HR services, and compliance, reducing typical nonprofit overhead from 20-30% to 9%. Donor advised funds under Tides Foundation charge 1-5% depending on structure, with Tides reporting a 54% DAF payout rate versus the 22.5% national average. Social Purpose Real Estate operates Tides Converge, providing below-market co-working space in San Francisco (150,000 sq ft in the historic Letterman Hospital at the Presidio, opened 1996) and New York (LEED-certified Manhattan building opened 2007), housing 70+ mission-driven organizations and saving Bay Area nonprofits over $13M in rent. Additional revenue derives from collective action fund management, impact investing services, and strategic advising.

Tides serves four primary customer segments: Social Change Leaders needing operational infrastructure (emerging nonprofits, grassroots organizers, social entrepreneurs), Individual and Family Donors seeking tax-efficient philanthropic vehicles, Corporations designing equity-centered philanthropy programs (including Google.org), and Foundations leveraging Tides' grantmaking infrastructure for collaborative funding. The organization employs 251-500 staff, is governed by an independent board, and operates without a parent company or external investor ownership, having grown organically across five decades. Its competitive position rests on network effects among 4,000+ grantees, switching costs from embedded infrastructure, the Nonprofit Centers Network advisory practice, and a 50-year institutional brand in progressive philanthropy infrastructure.

Revenue model

1. Fiscal Sponsorship Fees: Tides Center charges 9% of annual revenue for comprehensive fiscal sponsorship services including financial management, legal framework, and capacity-building support. Projects exceeding $1 million in operational activity may qualify for reduced fees on revenue above that threshold. Government funding carries a higher 15% fee due to increased auditing and reporting requirements.
2. Donor Advised Fund Administration: Fees range from 1% on standard donor advised funds to 5% for funds supporting single domestic or international projects or organizations. Tides Foundation holds over 400 donor advised funds and processes grant recommendations from fund advisors.
3. Social Purpose Real Estate: Tides Converge provides bi-coastal shared nonprofit workspaces in San Francisco and New York. Revenue is generated through below-market office space leasing and coworking programs. The San Francisco location opened in 1996 with 150,000 square feet, having saved Bay Area nonprofits over $13 million in rent.
4. Collective Action Fund Management: Tides manages collective action funds with independent advisory committees. These purpose-driven funds channel grants from multiple sources toward specific charitable purposes. Tides exercises legal compliance and mission alignment oversight while following IAC recommendations.
