Sweet Tuna Foundation concentrates its philanthropic support in a small number of large, unrestricted grants, favoring local Miami institutions as well as one national/international relief organization. The foundation’s giving is dominated by substantial general-purpose gifts to a regional hospital system, with additional major investments in faith-based humanitarian relief and contemporary arts in Miami.
Highly concentrated giving: very few, large grants (several six-figure gifts), repeat support to a core health-care grantee, and predominantly unrestricted/general-use awards rather than project-specific funding.
Sweet Tuna Foundation C/o Witkoff Group’s recent giving is marked by a single very large general-use gift to Samaritans Purse, paired with similarly large unrestricted support for Mount Sinai Medical Center Foundation in Miami Beach. That pattern points to a funder that uses flexible grants rather than tightly scoped project awards. The foundation’s support reaches healthcare, faith-based humanitarian relief, and Miami cultural institutions, but the dollar volume is concentrated in a few major recipients. Mount Sinai Medical Center Foundation appears as a repeated recipient across the recent grant record, with awards in both 2023 and 2025. A separate major grant went to the Institute of Contemporary Art Miami, showing that the foundation also backs arts institutions in its local market. Smaller awards extend to organizations such as Chabad Young Professionals Miami Beach, Foundation of Community Assistance and Leadership, and H3 Health Hope Healing, suggesting attention to community-serving groups alongside the larger institutional gifts. All of the listed recent grants were made for general use of the donee, which aligns with the foundation’s flexible funding style. The grant list shows a narrow number of recipients relative to the size of the awards, with most of the dollars flowing to a small set of organizations rather than a broad portfolio.
Healthcare is a central theme in the foundation’s giving. In 2025, it gave $450,000 to Mount Sinai Medical Center Foundation for general use of the donee, following a $495,000 grant to the same organization in 2023. That repeated support makes hospital funding one of the clearest parts of its recent grant history. Arts and culture also appear in the record. The foundation gave $150,000 to the Institute of Contemporary Art Miami in 2025, after earlier grants of $50,000 in 2023 and $39,000 in 2024, all for general use. Those awards show a continuing relationship with a Miami arts institution. Religious and humanitarian work is another visible area. A $500,000 grant in 2025 went to Samaritans Purse for general use, and a smaller $10,000 grant supported Chabad Young Professionals Miami Beach. The recent list also includes community-serving gifts such as $10,000 to Foundation of Community Assistance and Leadership and $1,000 to H3 Health Hope Healing.

Notable grantees: Mount Sinai Medical Center Foundation, Samaritan’s Purse, Institute of Contemporary Art, Miami
Grant size is highly skewed toward larger awards: the typical grant sits at $10,000 at the 25th percentile, $30,000 at the median, and $100,000 at the 75th percentile. Recent activity also includes very large outliers at $450,000, $495,000, and $500,000. The pattern suggests a foundation that mixes a few major commitments with smaller community grants. It is a private foundation, does not fund individuals, and does not make program-related investments. The recent record also shows repeat support to the same grantee across multiple years, especially Mount Sinai Medical Center Foundation and the Institute of Contemporary Art Miami.
The foundation’s giving is regional and heavily centered in Florida, which accounts for 53% of grants by recipient location and is also the top state by grant count.

All listed recent grants went to U.S. recipients. The strongest geographic pattern is local support in the Miami area, with a smaller set of grants reaching national organizations outside Florida.
