Corner Foundation Inc.

The Corner Foundation is a family-directed philanthropy vehicle operated by Frederick and Diana Elghanayan, co-founders of TF Cornerstone, one of New York City's largest privately held real estate development firms. With $16.3 million in assets and annual giving exceeding $1.7 million as of 2023, the foundation operates without paid staff — all grant decisions are made directly by the Elghanayan family board.

This is strictly an invitation-only funder. The foundation does not accept unsolicited proposals, does not maintain a functional website (corner.org returns no content), and does not publish application guidelines. Grant relationships typically begin through the family's personal and professional networks, particularly Diana Elghanayan's involvement with organizations like Citizens' Committee for Children of New York (a $750,000+ recipient).

For organizations seeking to build a relationship, the most effective approach is demonstrating alignment with the foundation's core giving areas — human services addressing food and housing insecurity, New York City cultural institutions, education (especially charter schools and higher education), and Jewish community organizations. The foundation shows strong loyalty to existing grantees: City Harvest has received $565,000 across 5 grants, and NOLS has received over $1 million across 4 grants, indicating multi-year deepening commitments. First contact should ideally come through a board member of a current grantee organization or through shared professional circles in New York real estate or nonprofit governance.

The Corner Foundation has grown its annual grantmaking dramatically over the past six years. Total giving increased from $548,850 in 2018 to $1,737,549 in 2023 — a 216% increase. Grants paid rose from $548,850 to $1,612,250 over the same period.

Grant size analysis: Across 246 total grants, the average award is $22,458. However, the distribution is highly skewed. The top 10 grantees account for $3,393,100 (61% of all giving), while smaller grants of $500-$10,000 are common for newer or smaller organizations. The largest single recipient is NOLS (National Outdoor Leadership School) at $1,010,000 across 4 grants, suggesting deep personal affinity.

Geographic concentration: New York dominates with 207 of 246 grants (84%). New Jersey accounts for 6 grants, Wyoming for 4 (likely NOLS-related), Virginia for 3, with California, DC, Illinois, Louisiana, Ohio, and Texas each receiving 2 grants.

Sector breakdown by top grantees: - Human services: City Harvest ($565K), Citizens' Committee for Children ($750K combined entities), Covenant House ($110K), Citymeals-on-Wheels - Health: Memorial Sloan-Kettering ($225K), Hospital for Special Surgery ($150K), Mount Sinai ($125K), NYU Langone ($115K) - Education: Blair Academy ($405K), NOLS ($1.01M), Success Academy, Cornell University - Arts/culture: Whitney Museum ($83K), Carnegie Hall, Apollo Theater, Brooklyn Museum - Jewish causes: Central Synagogue ($173K), Birthright Israel, Museum of Jewish Heritage

Financial sustainability: The foundation receives no new contributions — giving is funded entirely from net investment income ($1.1-2.1M annually). Assets have remained stable at $15.8-16.5M since 2020, indicating sustainable payout levels around 10-11% of assets.

The Corner Foundation sits in the mid-tier of New York family foundations with $16.3 million in assets. Compared to peers in the Philanthropy & Grantmaking NTEE category with similar asset levels:

The Corner Foundation stands out among its asset-class peers for two reasons. First, its payout rate of approximately 10-11% of assets significantly exceeds the 5% minimum required of private foundations, suggesting aggressive grantmaking relative to endowment. Second, unlike many foundations of this size that employ professional staff, the Corner Foundation operates with zero officer compensation and no formal application process — all decisions flow through the Elghanayan family directly. This makes it more nimble but also less accessible than peer foundations that maintain open application processes.

The Corner Foundation filed its 2024 tax return on November 14, 2025, reporting total assets of $16,265,748 and total revenue of $1,686,322. While the 2024 grants paid figure is not yet publicly available, the foundation maintained its upward giving trajectory through 2023 with $1,612,250 in grants paid.

The foundation's most recent publicly available grant data (2023) shows continued support for long-standing grantees including City Harvest, Central Synagogue, Memorial Sloan-Kettering, and Kasey's Key (13 grants totaling $77,500, their most frequently funded organization by count). No major leadership changes have been reported — Frederick Elghanayan continues as President, Diana Elghanayan as Director/Secretary/Treasurer, with Zoe and Ariel Elghanayan serving as Directors.

On the business side, TF Cornerstone has been active in the New York real estate market, pursuing a $1 billion office-to-residential conversion fund targeting distressed commercial properties. The firm was also honored at the 27th Annual LIC Partnership Luncheon for its contributions to Long Island City development. These business activities do not directly affect grantmaking but reflect the family's continued financial capacity and New York community engagement.

The most important thing to understand about the Corner Foundation is that it does not accept unsolicited applications. There is no form, no portal, no LOI process, and no published guidelines. The foundation's website (corner.org) contains no content. All grants are made at the discretion of the Elghanayan family board.

How to get on their radar: - Network through existing grantees. Citizens' Committee for Children of New York is the strongest connection point — Diana Elghanayan serves as its vice president. Board members of City Harvest, Central Synagogue, and NOLS may also provide warm introductions. - Demonstrate NYC impact. 84% of grants stay in New York. Organizations with strong New York City programming in food security, housing, youth services, or cultural programming align with the foundation's priorities. - Show institutional stability. The foundation's grantee list skews toward established organizations — Memorial Sloan-Kettering, Hospital for Special Surgery, Whitney Museum, Carnegie Hall. Startups or early-stage nonprofits appear infrequently. - Expect relationship-building before funding. The most heavily funded organizations receive grants year after year (Central Synagogue: 7 grants, City Harvest: 5 grants, Kasey's Key: 13 grants). Initial grants may be small ($500-$5,000) and grow over time. - Align with personal interests. The Elghanayans' giving reflects personal connections — Cornell University (Frederick's alma mater), Blair Academy (likely family connection), NOLS (outdoor education). Understanding the family's personal involvement in organizations provides signal about future giving directions. - Health institutions are a growth area. Combined giving to medical centers (Sloan-Kettering, HSS, Mount Sinai, NYU Langone) totals over $615,000, making healthcare an increasingly prominent focus.
