Ideal Applicant
A small-to-mid sized Jewish or faith-based community organization with existing ties to the foundation's network or local community, offering programs similar to prior grantees and seeking modest general-support or project grants.
Good Fit
- • Clear alignment with Jewish/faith-based charitable activities or Chabad-affiliated programming.
- • Existing relationship or referral to a foundation officer, trustee, or a recurring grantee.
- • Budget and request size in the foundation's historical range (hundreds to tens of thousands of dollars).
- • Programs operating in New York, New Jersey, Nevada, or California, especially New York.
Geography
Latest-year grants were paid across four states but are strongly concentrated in New York, which received roughly 60% of the dollars; the footprint is multi-state but regionally focused.
Recipient Variety
The latest year shows ten distinct recipients (all independent charities) and a stable set of returning grantees across multiple years, indicating moderate breadth but a thematically focused portfolio on Jewish/faith-based organizations.
New Applicants
The foundation's filings explicitly indicate grants are to preselected recipients and the latest year shows only one new recipient amid nine returning grantees; combined with no public application portal, unfamiliar applicants are unlikely to gain entry without an invitation or introduction.
