The Jack Weisberg Charitable Foundation concentrates its giving in a small number of large grants, providing substantial unrestricted/operational support to organizations working in international humanitarian relief and Jewish communal causes. Grants are focused and recurring — the foundation makes multi-six-figure awards and repeats funding to the same organizations rather than spreading many small gifts. Its giving pattern suggests a preference for high-impact partners that deliver relief overseas and strengthen Jewish community institutions in the New York/New Jersey region.
Highly concentrated: few, large grants totaling the foundation’s annual giving; repeat multi-grant relationships with select grantees; preference for unrestricted or general operating support over many small/project grants.
Jack Weisberg Charitable Foundation Inc shows a strong pattern of repeated, high-dollar support for a small set of organizations rather than broad, one-time philanthropy. Two large awards to Engine 27 Inc in New York — $470,000 in 2023 and $345,000 in 2024 — stand out, along with recurring support for Concern Worldwide (US) Inc and Uja Federations of NY. The foundation’s recent giving centers on operating expense support and charitable-purpose grants, including substantial awards to groups working in international humanitarian relief and Jewish communal service. Its portfolio also reaches health, education, and community organizations, but the recurring recipients indicate a clear preference for sustaining established partners. The grant sizes in the recent list range from $15,000 to $470,000, with several multi-year awards at the top of the schedule. This mix points to a funder that uses concentrated grants to support core organizational needs, especially for nonprofits that deliver relief services or serve Jewish communities in the New York and New Jersey region.
In international humanitarian relief, the foundation gave $275,000 to Concern Worldwide (US) Inc in 2023 and $225,000 in 2024, then followed with another $25,000 in 2025. It also awarded $35,000 to Doctors Without Borders in 2025, plus earlier gifts of $25,000 in 2023 and $25,000 in 2024. In Jewish communal support, Uja Federations of NY received $275,000 in 2023, $25,000 in 2024, and $35,000 in 2025. The foundation also funded New Alternatives for Children with $25,000 in 2023 and $15,000 in both 2024 and 2025. Beyond those areas, it supported Hudson Catholic Regional High School with $25,000 in 2023 and $15,000 in 2024, and Frost Valley YMCA with $25,000 in 2025.
Typical grants cluster tightly around $10,000 at the 25th percentile, $10,000 at the median, and $25,000 at the 75th percentile, even though the foundation also makes much larger awards at the top of the range. The recent record shows recurring support to the same organizations across multiple years, especially Engine 27 Inc, Concern Worldwide (US) Inc, Doctors Without Borders, Uja Federations of NY, and New Alternatives for Children. The foundation is a private grantmaker that does not fund individuals and does not make program-related investments. The grant descriptions repeatedly reference charitable purpose and operating expense support, indicating a preference for general operating or core support rather than narrowly restricted project funding.

Notable grantees: Engine 27 Inc, Concern Worldwide (US) Inc, UJA Federations of NY
Grant recipients are entirely in the United States. New York is the top state by grant count, and New Jersey accounts for 19% of grants, showing a strong regional footprint around the HQ area. New York City appears frequently, including recipients in New York, NY such as Engine 27 Inc, Concern Worldwide (US) Inc, Doctors Without Borders, Uja Federations of NY, and New Alternatives for Children. Other recurring locations include Basking Ridge, NJ; Jersey City, NJ; and Allentown, PA. The reach also extends to Washington, DC, Memphis, TN, Dallas, TX, Topeka, KS, Chestnut Hill, MA, and Claryville, NY.
The recent grants point to three main lanes: international humanitarian relief, Jewish communal support in the New York area, and operating support for selected nonprofits. Examples include Concern Worldwide (US) Inc, Uja Federations of NY, and Engine 27 Inc, with grant descriptions often marked “charitable purpose” or “fund operating expenses.”
Yes. Several organizations appear in multiple years: Engine 27 Inc received $470,000 in 2023 and $345,000 in 2024; Concern Worldwide (US) Inc received $275,000 in 2023, $225,000 in 2024, and $25,000 in 2025; Doctors Without Borders appears in 2023, 2024, and 2025; and Uja Federations of NY appears in 2023, 2024, and 2025.
The distribution is centered on smaller awards: the 25th percentile is $10,000, the median is $10,000, and the 75th percentile is $25,000. The foundation also makes larger outlier grants, including awards in the six-figure range.
The foundation gives most often in New York, while New Jersey receives 19% of grants. The recipient list is otherwise U.S.-only, with repeated grants to organizations in New York, NY and several awards in New Jersey communities such as Basking Ridge and Jersey City.
Grant descriptions repeatedly say “charitable purpose” and, in one major case, “fund operating expenses.” That pattern suggests general support for organizational capacity and core mission continuity rather than a narrow project-only approach.
