Ideal Applicant
Established nonprofits with an existing track record—especially arts, health, education, or university programs—preferably with a New York presence or strong NY programmatic ties and capacity to manage mid-sized unrestricted grants.
Good Fit
- • Organization has an established operating history and fiscal stability.
- • Programs align with arts, health, education, or university research priorities reflected in past grants.
- • Demonstrable New York presence or significant program activity in New York.
- • Ability to use general/unrestricted support effectively and report on outcomes.
- • Existing relationship, introduction, or history of prior funding from the foundation or its network.
Geography
Grants were made to recipients in seven states, showing a multi-state footprint, although more than 60% of dollars flowed to New York in the latest year.
Recipient Variety
The latest year shows a broad recipient set (38 distinct organizations) across multiple sectors (arts, health, education, universities), indicating a wide institutional variety despite some dollar concentration.
New Applicants
Direct evidence shows a high repeat rate (33 returning recipients) and the foundation states it funds only preselected applicants; while five new recipients appeared in the latest year, the combination of invitation-style practice and repeat funding suggests unfamiliar applicants are unlikely to gain entry without introductions.
