Ideal Applicant
A small to mid-sized Illinois nonprofit (especially Rockford-area) seeking program support and able to submit a mailed application with budgets and governance information.
Good Fit
- • Located in Rockford or nearby in Illinois
- • Requesting program-level support in the typical range observed (~$3K–$20K)
- • Able to provide two years of budgets, board/officer lists, and tax status documentation
- • Established local reputation or prior relationship with community institutions (parks, YMCA, shelters, youth groups)
- • Comfortable using a mailed application route and providing the requested administrative details
Geography
Observed giving is entirely in Illinois with a clear Rockford-area focus; all recorded grants in the dataset were in-state and concentrated in the same metro.
Recipient Variety
The latest year shows ten distinct nonprofit recipients across arts, youth, human services and parks, with a mix of repeat grantees and new entrants; dollar concentration is moderate (top five took ~75%), but the number of independent recipients indicates a reasonably diverse local portfolio.
New Applicants
There is an explicit application instruction set and a mailing address with a rolling submission process, and the latest year included multiple new recipients (four), so unfamiliar local organizations appear to be able to access funding.
