What Mosaic does

Mosaic Environmental Fund is a U.S.-based 501(c)(3) nonprofit that functions as a national collaborative funder and field catalyst for the environmental movement. Founded in 2020 with seed funding from the Hewlett, Packard, Walton Family, and Pisces Foundations, Mosaic was created after an 18-month collaborative design process involving over 100 NGO, philanthropy, and academic leaders. The organization operates as a fiscally sponsored project of the Tides Center (EIN 94-3213100), headquartered in San Francisco. Its core mission is to strengthen environmental movement infrastructure—including networks and coalitions, narrative capacity, leadership development, and advocacy tools—by coordinating pooled philanthropic funding across portfolios.

Mosaic's core programmatic offerings include annual collaborative grantmaking cycles, a Leadership Council of grassroots, nonprofit, and philanthropy leaders that governs strategy, investments in state-level coordinating infrastructure, narrative capacity building, leadership development programs, advocacy tools and training, grantee networking convenings, a cross-funder community of learning, and the annual "Mapping the Moment" landscape analysis. Over five years, Mosaic has made 418 grants totaling $32M, supporting 800+ co-applicants and 8,300+ benefiting organizations. The 2024 Movement Mobilization Hubs alone facilitated at least $73M in successful federal funding applications, demonstrating significant leverage beyond direct grantmaking.

Mosaic's business model is philanthropic rather than commercial: it raises contributed revenue from foundations (including David Rockefeller Fund, Keith Campbell Foundation, Walton Family Foundation, Rockefeller Brothers Fund, Stavros Niarchos Foundation, and others) and accepts gifts from donor-advised funds. The organization does not sell products or services; its "pricing" is essentially the size of grants disbursed and the value of convening, learning, and field-intelligence services provided to funders and grantees. Technology infrastructure is limited to standard nonprofit tools—Salesforce.org for the grantee portal, Mailchimp for email, and Google Analytics for web tracking—and Mosaic is explicitly not a technology platform. Distribution occurs through annual grant cycles with a mix of renewals, open calls, and selective grantmaking, governed by the Leadership Council.
