Ideal Applicant
Small-to-midsize organizations focused on children and youth—especially education, leadership development, entrepreneurship, or intermediary/network roles—often with a New York connection or demonstrated partnership with similar national intermediaries.
Good Fit
- • Work focused on youth leadership, education, or entrepreneurship.
- • Track record partnering with national intermediaries or peer funders (e.g., participatory networks).
- • Capacity to absorb grants in the foundation’s observed range (roughly $2.5K–$160K, with many awards under $25K).
- • Existing relationships or introductions into the foundation’s networks (program staff, partners, or intermediaries).
- • Presence or program activity in New York or one of the states previously funded.
Geography
Observed grants span multiple states (eight in 2024) and historically covered more states, so giving is multi-state; however, a large portion of dollars are concentrated in New York (about 43% in 2024 and higher in prior years).
Recipient Variety
The foundation funded many distinct recipients each year (27, 21, 16) and the most recent year shows entirely new recipients, indicating a broad and changing recipient set despite dollar concentration among a few large awards.
New Applicants
Behaviorally the foundation regularly funds new organizations (all 16 recipients in 2024 were new), which suggests it is not strictly closed, but the website and application notes state it only supports preselected applicants and does not accept unsolicited requests, reducing the practical likelihood that an unfamiliar group can enter the portfolio without a referral.
