Maddie’s Fund is an American private foundation established in 1999 by philanthropists Dave Duffield and Betsy Duffield in memory of their daughter. The foundation focuses on improving the welfare of companion animals through funding, research, and capacity-building for animal shelters, veterinary institutions, and nonprofit organizations. Over two decades it has invested in initiatives spanning shelter practices, veterinary education, data systems, and public outreach to advance lifesaving and rehoming efforts.

History

Maddie’s Fund was created by Dave Duffield and Betsy Duffield following the death of their daughter, with an early emphasis on transforming the landscape of animal shelters in the United States. In the 2000s the foundation supported pilot projects that intersected with institutions such as University of California, Davis and University of Florida to develop shelter medicine curricula and evidence-based practices. During the 2010s Maddie’s Fund expanded grantmaking to include collaborations with organizations like ASPCA and Humane Society of the United States, while engaging with municipal partners including San Francisco agencies and county humane societies. The foundation’s historical trajectory includes investments in technology platforms and nationwide campaign models that echo efforts by other philanthropic entities such as The Bill & Melinda Gates Foundation in global health and Robert Wood Johnson Foundation in public health policy.

Mission and Programs

Maddie’s Fund’s mission centers on increasing lifesaving for homeless animals through innovation in shelter operations, veterinary education, and community-based programs. Programmatic work aligns with academic partners like University of Pennsylvania School of Veterinary Medicine and clinical training at Cornell University College of Veterinary Medicine, supporting curriculum development and shelter medicine fellowships. The foundation has funded programs addressing adoption, foster care, spay/neuter services, and shelter capacity-building, often collaborating with service providers such as Best Friends Animal Society and municipal systems in Los Angeles County. Its program portfolio mirrors strategic philanthropy models applied by foundations like Carnegie Corporation of New York in education reform and Kresge Foundation in nonprofit capacity-building.

Funding and Grants

Maddie’s Fund deploys grants to animal welfare organizations, academic institutions, and municipal shelters, using competitive grant cycles and targeted funding initiatives. Major grantees have included San Francisco SPCA, Humane Society Silicon Valley, and veterinary research centers at universities such as Texas A&M University and Ohio State University. The foundation has also offered challenge grants and matching funds to stimulate local funding pools, echoing strategies used by MacArthur Foundation in seed funding and Ford Foundation in social innovation. Grantmaking criteria commonly emphasize measurable outcomes, scalability, and partnerships with local governments or nonprofit networks like United Way chapters when relevant.

Research and Impact

Research funded by Maddie’s Fund has focused on shelter medicine, adoption dynamics, behavioral assessments, and data-driven operations. Studies supported through partnerships with University of Wisconsin–Madison, University of California, Davis, and University of Missouri have informed best practices in intake diversion, foster programs, and post-adoption support. The foundation contributed to the development of data tools and metrics akin to initiatives led by The Pew Charitable Trusts in data transparency, enabling shelters to track live-release rates and capacity metrics. Peer-reviewed publications and conference presentations at venues such as the North American Veterinary Community and the Association of Shelter Veterinarians have disseminated findings supported by the foundation, influencing practice across municipal systems and nonprofit providers.

Partnerships and Collaborations

Maddie’s Fund has formed collaborations with academic centers, nonprofit networks, veterinary associations, and municipal agencies to scale evidence-based practices. Academic partners include University of Florida and North Carolina State University for veterinary training, while nonprofit collaborations have involved Best Friends Animal Society and PetSmart Charities on adoption and outreach programs. The foundation has worked with professional organizations such as the American Veterinary Medical Association and the Association of Shelter Veterinarians to influence standards and continuing education. International exchanges and pilot projects have connected Maddie’s Fund-supported teams with practitioners associated with Royal Society for the Prevention of Cruelty to Animals and other global actors.

Governance and Leadership

Governance of Maddie’s Fund has reflected a private family foundation model with a board of directors and senior staff overseeing strategy, grantmaking, and program evaluation. Leadership includes founders Dave Duffield and Betsy Duffield and appointed executives with backgrounds in nonprofit management, veterinary medicine, and philanthropy. The foundation has engaged advisory boards drawing expertise from institutions including University of California, Davis veterinary faculty, leaders from Humane Society of the United States, and executives from national animal welfare organizations. Its governance practices align with standards used by foundations such as Council on Foundations members and philanthropic entities following best-practice fiduciary models.

Notable Initiatives and Campaigns

Notable initiatives financed or convened by Maddie’s Fund include large-scale shelter transformation projects, national adoption campaigns, and the creation of educational fellowships in shelter medicine. Campaigns have partnered with municipal shelters in jurisdictions like San Francisco and Alameda County to pilot intake diversion and foster expansion, producing models replicated by regional coalitions. The foundation’s investments in data platforms and public awareness campaigns have complemented efforts by Petfinder-linked networks and advocacy groups such as Actors and Others for Animals in increasing visibility for adoptable pets. Specialized initiatives supporting veterinary residency programs and conference funding have reinforced links with academic centers including Cornell University and University of Pennsylvania.
