Jack & Valerie Guenther Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- The foundation works by invitation only and contributes only to organisations it has preselected, so a small charity should not send an unsolicited request.
- The filing describes its main theme as public art and education, including loans for public exhibition and education and a sculpture it donated to a cancer centre, so work outside those areas is unlikely to fit.
- The filing does not state a grant range or a geographic focus, so it does not give a realistic request size; its $5,172,165 total paid out indicates scale but not typical amounts.
- If your organisation has a genuine connection to the foundation or its trustees, raise it through people who know them rather than with a cold approach, and do not expect a timeline or submission process because none is stated.
