Ideal Applicant
A small or mid-sized New York–based nonprofit (or nearby CT organization) seeking operating support in education, health, faith-based or community services and able to secure a warm introduction or preselection by the foundation or its advisors.
Good Fit
- • Organization is located in New York or has a clear NY program presence.
- • Request is for operating support at typical award sizes (low‑to‑mid five figures or below).
- • Mission aligns with education, hospitals/health, community service, or faith-based causes.
- • Ability to obtain a referral or introduction through a trustee, advisor, or O'Connor Capital Partners contact.
- • Track record of stable operations and clear local impact.
Geography
Grantmaking spans multiple states but is heavily weighted to New York — roughly 80% of 2024 dollars went to NY recipients while five states were represented in that year.
Recipient Variety
The latest year shows 25 distinct recipients and the three-year history lists dozens of independent grantees with 17 repeat recipients across years, indicating a broad portfolio despite financial concentration in a few top grantees.
New Applicants
There is behavioral evidence of new grantees (8 new recipients in 2024 and 15 in 2023), but the foundation publicly states it funds by preselection only, so unsolicited applicants appear possible but are unlikely to be successful without an introduction or nomination.
