Jeff and Marieke Rothschild Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- The foundation does not accept unsolicited requests and makes grants only to organisations it has preselected, so you should not send a cold request; the only route the filing supports is being invited or reaching it through an existing connection.
- If you are invited or already in contact, a request near $500,000 would match the median grant, since half of its grants to organisations are $500,000 or less, though about 8 in 10 grants fall between $125,000 and $5,000,000, a typical band rather than a ceiling.
- A share of 55% of its grant dollars to organisations went to groups it had also funded in its recent filings, so a new applicant should expect to be compared with established relationships.
- The filings show a broad mix of work, from food relief and conservation to medical research, but no geographic focus is stated, so your region should not be assumed to rule you in or out.
- The filing gives no indication of when invitations are made, so timing is hard to plan around.
