Overview
The Borrego Foundation is a private family foundation established in the 1990s by Stephen Lieber, a Wall Street investor described by Fortune as the "king of balanced funds." The foundation received its 501(c)(3) designation in April 1998. With assets of approximately $46 million as of 2024, the foundation disbursed approximately $3.8 million in charitable grants in 2024, representing 89.6% of total expenses. The foundation has shown steady growth, with assets increasing from approximately $14.5 million in 2011 to its current level. Grant-making focuses primarily on reproductive rights and women's issues, environmental conservation, and policy research, with a particular emphasis on organizations working in New York and at the national level.

Application Process & Timeline
How to Apply
The Borrego Foundation does not have a public application process.
This is a private family foundation that makes grants at the discretion of its trustees. Grants are initiated by trustees based on their own research, existing relationships, and strategic priorities rather than through open solicitation of proposals.
The foundation does not maintain a public website, published grant guidelines, or application forms. Organizations cannot submit unsolicited proposals through a formal application portal.
Getting on Their Radar
The foundation's giving patterns suggest grants are made to organizations where trustees have direct knowledge or involvement. Strategies for potential grantees include:
Board and Leadership Connections: Given Mary Rubin's extensive board service with The Nature Conservancy, Planned Parenthood, and Center for Reproductive Rights, organizations working in these networks may have indirect pathways to foundation awareness.
Sector Leadership: The foundation supports well-established national organizations with proven track records. Building prominence in the reproductive rights, environmental conservation, or progressive policy sectors may increase visibility.
Geographic Presence: While the foundation gives nationally, having a New York presence or New York-focused programs may be advantageous given the foundation's Larchmont location.
Alignment with Trustee Interests: Research shows the foundation supports causes closely aligned with the personal commitments of its leadership, particularly reproductive rights, environmental conservation, and evidence-based policy research.
Decision Timeline
Decision timelines are not publicly available. As a private foundation with trustee-directed grantmaking, decisions are made on the trustees' own schedule rather than fixed deadlines.
Success Rates
Success rate data is not available, as the foundation does not accept unsolicited applications.
Reapplication Policy
Not applicable due to invitation-only grantmaking model.
Application Success Factors
Since this foundation does not accept unsolicited applications, traditional application success factors do not apply. However, organizations seeking foundation support should note:
Strong Organizational Leadership: The foundation's grants go to major national organizations with established reputations and strong governance structures.
Mission Alignment: The foundation demonstrates clear commitment to reproductive rights, environmental conservation, and progressive policy research. Organizations outside these areas are unlikely to receive support.
Scale and Impact: With typical grants in the tens or hundreds of thousands of dollars going to a small number of organizations annually, the foundation appears to focus on established organizations capable of significant impact rather than emerging groups.
Board Connections: Given the foundation's structure, personal knowledge of the organization through board service, sector leadership, or professional networks appears to be a primary factor in grantmaking decisions.
Geographic Considerations: While the foundation makes national grants, its focus areas identify "primarily in New York" as a key geographic priority.
