The Klesse 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 gives only to charitable organisations it has preselected and does not accept unsolicited requests, so a charity that has not been invited should not send one.
- Published sources give San Antonio as its priority, and its stated remit covers scientific, educational, cultural and religious organisations, so work in those fields and that city is the closest fit.
- Giving was $1,720,226 in the latest year, down from $7,661,641 and $9,510,375 in the two years before, so the funds available appear to be shrinking.
- The filing gives no grant range, so a grant writer cannot judge a typical request size from it, and the most useful first step is to seek an invitation rather than to size a request.
