Ideal Applicant
An established nonprofit or intermediary working on social connection/cohesion, early childhood funder collaboratives, or philanthropy/civic networks with an existing funder relationship or network introduction.
Good Fit
- • Work squarely aligned with social connection, civic cohesion, or early childhood funder collaboratives.
- • Existing ties or introductions through funder networks and intermediary organizations.
- • Organizational scale and capacity to serve as a state or national intermediary.
- • Track record for general operating support or sustained program work rather than one-off pilots.
- • Presence in or connections to the foundation’s common states (DC, MA, NY) or national funder networks.
Geography
In the latest year grants reached organizations in five different states, but the portfolio is regionally concentrated: 64% of 2024 dollars went to DC-based recipients, with recurring support also visible in MA and NY.
Recipient Variety
The foundation funded 7 distinct recipients in 2024 (and funded up to 12 distinct recipients in 2022), showing a moderate spread of independent organizations; however giving is financially concentrated among a few repeat grantees.
New Applicants
The foundation explicitly states grants are by invitation and does not accept unsolicited proposals; coupled with a high repeat rate (six of seven 2024 grantees were returning) and only one new recipient in 2024, it appears unlikely an unfamiliar applicant could enter the portfolio without a warm introduction or relationship.
