FUNDING PARTNERS
Mosaic is a proven collaborative fund trusted by leading philanthropies to deliver high‑impact, field‑strengthening investments.
What we offer
Strategic, pooled funding
We coordinate and align funding across funding portfolios to make grants that amplify philanthropic impact across the entire ecosystem. By investing in connective tissue of the movement, we unlock greater innovation, collaboration, alignment, and effectiveness – from local advocates to national coalitions.
Facilitation of collaborative, cross-sector leadership
We cultivate strong and interconnected leaders through our Leadership Council, open grantmaking processes that catalyze collaborative projects and relationships, and intentionally designed grantee networking that strengthens bonds.
Deep field insights
Our grantmaking and donor advising is grounded in data, research, and the expertise of diverse movement leaders, giving us a nuanced understanding of field needs and emerging opportunities.
Rigorous learning and evaluation
Our monitoring, learning, and evaluation process helps identify the most powerful levers for climate and environmental progress. These insights inform our own strategy and help strengthen grantmaking practices across the field.
Cross-funder community of learning
Our intentional engagement with funders surfaces field intelligence, accelerates shared understanding, and informs smarter, more coordinated investments across the movement.
Collaborative funds’ outsize impact, rooted in relationships of trust and authentic partnerships, is chronicled in reports from Philanthropy Together and the Bridgespan Group.
