Knapp-Swezey Foundation
At a glance
Key takeaways
- The foundation's stated focus is Brookhaven, and its application information asks that projects be in the Town of Brookhaven in Suffolk County, New York, so a charity whose work is outside that town should not expect to fit.
- Most of its grants are modest: about 8 in 10 of its 117 grants to organisations fall between $10,000 and $500,000, and half are about $27,500 or less, so a request in that region matches its typical giving, although its largest grant was $20,000,000.
- Apply by letter setting out the project's nature, budget, beneficiaries and other funding sources; no deadlines are given in the filing, and it accepts applications.
- Repeat recipients received 96% of its grant dollars to organisations, so it leans heavily on organisations it already funds, and a new applicant should keep that in mind when deciding how to approach it.
