The Ainslie Foundation makes a small number of very large, often repeat grants to organizations across education, youth services/social welfare, conservation, and scientific research. Giving is national in reach (beneficiaries include New York institutions and regional youth organizations) and includes both direct service providers and philanthropic intermediaries. The foundation appears to favor institutional, high-impact partners—independent schools, scholarship and research institutions, major conservation groups, and youth development organizations—rather than many small community grants.
Ainslie Foundation’s largest recent grants show a pattern of concentrated support for institutional partners in education, social services, conservation, and research. One of the clearest examples is a $6,725,000 grant to Episcopal High School, alongside seven-figure commitments to the Robin Hood Foundation and the Wildlife Conservation Society. The foundation also backs repeat recipients, including Maverick Capital Foundation, which received grants of $5,000,000, $2,000,000, and $1,000,000 across 2023 to 2025. That repeat pattern points to a funder that often returns to the same organizations rather than spreading support across many one-off awards. Its portfolio includes independent schools, youth-serving groups, major environmental organizations, biomedical research institutions, and philanthropic intermediaries. Recent awards also reached Boys & Girls Clubs of Martin County, Boys' Club of New York, Cold Spring Harbor Laboratory, and The Rockefeller University, showing a mix of direct service, scientific research, and pooled philanthropy. The foundation’s giving is national in scope and appears to favor established organizations with large operating capacity and broad reach.
Education is a major thread in the foundation’s recent grants. It gave $6,725,000 to Episcopal High School for education, $1,510,000 to Jefferson Scholars Foundation for education, and $275,000 to Bowdoin College for education. In biomedical and medical research, the foundation supported Cold Spring Harbor Laboratory with $1,100,000, The Rockefeller University with $600,000, Broad Institute with $250,000, and Johns Hopkins University with $150,000 for a neutrophil grant. Environmental preservation is another recurring area, with $2,600,000, $2,100,000, $2,000,000, and $150,000 going to Wildlife Conservation Society across 2023 and 2025. The foundation also made community-outreach awards to Boys & Girls Clubs of Martin County and Boys' Club of New York, each appearing more than once in the recent-grants list.
Ainslie Foundation’s typical grant size is $10,000 at the 25th percentile, $10,000 at the median, and $50,000 at the 75th percentile, which sits alongside a small number of much larger awards in the recent-grants list. The pattern is repeat giving: several recipients reappear across multiple years, including Maverick Capital Foundation, Robin Hood Foundation, Wildlife Conservation Society, Episcopal High School, and Boys & Girls Clubs of Martin County. It is a regular funder rather than a donor-advised fund, and it funds individuals. The grant list suggests a mix of operating support, institutional support, and targeted project grants, including research, education, conservation, and community programs.
