Ideal Applicant
A Minnesota-based 501(c)(3), especially a performing-arts or cultural organization seeking general operating support in the typical $5K–$25K range.
Good Fit
- • Located in Minnesota, preferably in the St. Paul/Minneapolis region.
- • Mission in performing arts, music, theater, or related arts and culture activity.
- • Request framed as general operating support or steady program funding.
- • Ability to submit the Minnesota Common Grant Application or a concise five-page proposal.
- • An established organization with some operating track record (many returning grantees are funded).
Geography
Giving is overwhelmingly in Minnesota (about 99% of dollars); only one small out-of-state award was observed, so the footprint is effectively in-state.
Recipient Variety
The foundation funded many distinct independent charities each year (about 59–68 recipients), primarily arts and community organizations, indicating a broad recipient set for its size.
New Applicants
Direct evidence shows roughly a dozen new recipients each year and the foundation publishes clear submission instructions (accepts proposals any time and recommends the Minnesota Common Grant Application), so unfamiliar applicants have a plausible entry route.
