Application Success Factors
Since this foundation does not accept unsolicited applications, traditional application success factors do not apply. However, understanding what the foundation values can be helpful:
Strong Environmental Focus: The foundation's grantmaking reflects the Horns' deep commitment to environmental causes. Organizations working on climate action, natural resources conservation, clean air and water, and environmental education align with their documented interests.
Board Relationships Matter: Both Cindy and Alan Horn have served on numerous boards over decades. Many grants likely flow to organizations where they have personal involvement or where their fellow board members can vouch for impact.
Entertainment Industry Connections: Alan Horn's legendary career in entertainment (Warner Bros., Disney) and the couple's co-founding of Environmental Media Association suggests potential interest in organizations connecting environmental issues with media and storytelling.
California and Los Angeles Focus: While the foundation makes grants nationally, there appears to be particular interest in Los Angeles-area organizations, especially those focused on local environmental issues like Heal the Bay (Santa Monica Bay cleanup) and Coalition for Clean Air.
Long-term Commitment to Causes: The Horns' philanthropic track record shows sustained, decades-long commitment to particular causes rather than trend-following. They were environmental advocates before it was mainstream.
Key Takeaways for Grant Writers
-
No Public Application Process: This foundation does not accept unsolicited proposals. Do not send applications or letters of inquiry unless specifically invited.
-
Relationship-Based Grantmaking: Grants flow through personal connections, board relationships, and trustee discretion. Building awareness through shared board members or sector connections would be the only potential pathway.
-
Strong Environmental Alignment: The foundation's grantmaking reflects the founders' passionate, decades-long commitment to environmental causes, particularly NRDC, coastal conservation, clean air, and climate action.
-
Entertainment-Environmental Nexus: The Environmental Media Association connection suggests potential interest in organizations that bridge entertainment/media and environmental advocacy.
-
Substantial Resources: With assets exceeding $51 million and annual giving of $3-5 million distributed among approximately 60-65 grants annually, this is a significant funder within their areas of interest.
-
Private Family Foundation Model: This foundation exemplifies classic private family foundation grantmaking - focused on causes the founders care deeply about, distributed through personal knowledge and relationships rather than competitive application processes.
-
Not a Viable Prospect for Most Organizations: Unless your organization has existing connections to the Horn family, their network, or operates in their core interest areas with potential for introduction through mutual contacts, this foundation should not be considered a realistic funding prospect.
