About Horizon Foundation
The Horizon Foundation concentrates its giving on large-scale environmental conservation and park support, primarily through major gifts to established land- and water-protection organizations. Grants are sizable and directed to institutional operating support, with an additional orientation toward higher-education philanthropy as seen in a substantial gift to a university foundation. The foundation favors a small number of high-impact partners rather than many small grantees.

About Horizon Foundation
A $20 million challenge grant commitment over four years defines The Horizon Foundation’s current public program: it is using that pool to support fee-simple acquisitions and conservation easements for land and water protection. That orientation matches the foundation’s recent record of large grants to conservation organizations and Texas park-support groups, with a smaller set of university and community awards mixed in. The biggest recent gift went to The Nature Conservancy, which appears multiple times across the grant list in both 2024 and 2025. Another major recipient is Texas Parks and Wildlife Foundation, which also shows repeated support across several years. The foundation’s giving pattern points to sustained backing for established institutions rather than one-off project scatter. Alongside environmental grants, the portfolio includes a substantial award to OU Foundation, showing that higher education sits within the same larger philanthropic frame. The result is a grantmaking profile centered on land, water, and conservation infrastructure, with recurring support for a small number of organizations that align with those priorities.
What Horizon Foundation Funds
Land and watershed protection is the clearest theme in the foundation’s current program work. The challenge grant program is explicitly built to support fee-simple acquisitions and conservation easements, and the recent grant list includes $2,500,000 to The Nature Conservancy for general support. Texas conservation infrastructure is another recurring lane: Texas Parks & Wildlife Foundation received $1,778,500 in 2023 for charitable operations and additional support in 2024 and 2025. The foundation also backs conservation-adjacent organizations tied to land stewardship in Texas, including $200,000 to Texas Agricultural Land Trust for general support and $125,000 to Texas Land Conservancy for charitable operations. Beyond conservation, it has made a major higher-education award through OU Foundation, indicating that the portfolio is not limited to environmental work alone.
How Horizon Foundation Gives
The Horizon Foundation’s grant sizes are substantial: the typical grant is $46,750 at the 25th percentile, $75,000 at the median, and $100,000 at the 75th percentile. The recent record also shows much larger awards at the top end, including seven-figure commitments. Grantmaking is repeat-oriented rather than one-off: several organizations appear in multiple years, including The Nature Conservancy, Texas Parks & Wildlife Foundation, Mane Gait, and OU Foundation. The foundation does not fund individuals and does not make program-related investments. The grant list reflects operating and general support as the dominant funding mode, with challenge-grant language used in its active land-protection program.
