About Greenbaum Foundation
The Greenbaum Foundation concentrates almost all of its giving on animal protection and related movements, providing large, unrestricted general operating support to organizations that advance animal welfare, plant‑based diets, and systemic change for animals. Grants are high-dollar and targeted to a small set of national or international advocacy organizations rather than many small local charities.

About Greenbaum Foundation
The Greenbaum Foundation’s giving is built around animal advocacy and plant-based nutrition, with large unrestricted grants to a relatively small set of organizations advancing food-system change, humane policy, and movement infrastructure. In the recent grants list, Karuna Foundation received $1,060,873 in 2025 and Free to Thrive-Thrive Philanthropy received $833,602 in 2024, both as general funding. That pattern continues across recurring support for organizations working on farmed animal welfare, legal advocacy, public education, and lifestyle medicine. The foundation also funds media and documentary projects tied to its goals, treating film and public-awareness work as part of the same change strategy. Its portfolio includes groups focused on advocacy research, legal approaches to animal protection, and organizations that help other nonprofits build capacity. Several grantees appear more than once across the years, which suggests ongoing relationships rather than one-off awards. The grantmaking profile is concentrated, purpose-driven, and built around flexible support rather than restricted project-by-project funding.
