The Weill Family Foundation concentrates philanthropic support on major research universities and higher-education institutional pledges, primarily funding capital/pledge fulfillment for prominent University of California campuses. Grants are large, strategic donations rather than many small awards, indicating a focus on sustaining flagship academic and research programs. Although based in Albany, NY, the foundation directs substantial, repeated support to California public research institutions.
Highly concentrated: a very small number of large grants concentrated on repeat grantees (UCSF, UC Berkeley, UC Davis) mostly designated as satisfaction of pledges rather than general operating support.
The Weill Family Foundation’s largest recent grants are pledge-satisfaction payments to University of California San Francisco Foundation, including $11,000,000 in 2024 and $9,653,607 in 2025. That pattern points to a funder built around honoring major commitments rather than distributing many small awards. Across the recent grant list, the foundation repeatedly directs substantial support to University of California institutions, especially UCSF and Berkeley, with additional funding for UC Davis. The same approach appears in other large gifts: a $3,200,000 pledge payment to Naf in New York in 2024 and a $2,500,000 pledge payment to Uc Davis Foundation in 2025. The foundation’s giving also reaches beyond higher education into selected cultural, health, and community organizations. Recent awards include support for New York Historical Society, Citymeals on Wheels, Hebrew Home for the Aged, Carnegie Hall, Alvin Ailey Dance Foundation, and the Leukemia & Lymphoma Society. The overall picture is of a regular funder making strategic, often large, commitments to institutions, with a strong emphasis on pledge fulfillment and flexible support.
Biomedical and health sciences research is a clear thread in the recent record. In 2023, The Weill Family Foundation gave $1,000,000 to University of California San Francisco Foundation for general charitable needs, alongside larger pledge payments to the same institution in other years. Higher-education capital and pledge support is another core area: the foundation gave $5,000,000 to University of California Berkeley Foundation in 2024 for satisfaction of pledge and another $3,753,607 in 2025 for the same purpose. The foundation also funds select cultural institutions, including $100,000 to The Carnegie Hall Corporation in 2024 and $50,000 in 2025. Community and social-service support appears in gifts such as $240,000 to Citymeals on Wheels and $500,000 to Hebrew Home for the Aged, both listed as satisfaction of pledge.
Typical grants are large, with a p25 of $23,750, a median of $100,000, and a p75 of $1,550,000. The recent record is dominated by one-time disbursements labeled satisfaction of pledge, which suggests commitment fulfillment rather than open application-based awards. Several recipients appear more than once across years, including University of California San Francisco Foundation, University of California Berkeley Foundation, Alvin Ailey Dance Foundation Inc, and Lang Lang International Music Foundation Inc. The foundation is classified as a regular funder, does not fund individuals, and does not make program-related investments.
