Grey Rocks Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- Do not send an unsolicited request, because the foundation makes contributions only to preselected charitable organisations and does not accept them.
- Its filing shows no stated geographic focus, and its grants have gone mainly to organisations in New Hampshire, Massachusetts, New Jersey and Utah, so these states describe where grants have gone rather than who may apply.
- Most of its grants are modest: half of its 272 grants to organisations were $10,000 or less, and about 8 in 10 fall between $1,500 and $50,000, although its largest grant was $510,000, so a request in that typical band suits its pattern.
- Its giving is strongly repeat: 92% of its grant dollars to organisations in its latest filing went to organisations it had also funded in the two filings before, so most of its money goes to existing recipients.
