Susan S and Kenneth L Wallach Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- The foundation says it does not accept unsolicited requests and is by invitation only, so a cold application falls outside how it takes funding requests.
- Its grant dollars are heavily concentrated in repeat recipients: 99% of grant dollars went to organisations it had also funded in earlier filings, so a first approach should rest on an existing connection.
- A request near $10,000 sits in the middle of its record, since half of its 156 grants to organisations were $10,000 or less and the median was $10,000; about 8 in 10 grants fall between $500 and $150,000, and the largest was $1,250,000.
- The filings show most grants in New York, Massachusetts and New Jersey, but no geographic focus is stated, so treat this as a pattern rather than a rule.
- Its record is general support across a broad mix of organisations, so fit depends on your organisation's work rather than a stated project theme.
