Key takeaways

  • If your work is in Maine and benefits Maine residents, and you are a US tax-exempt public charity or a political subdivision, the Foundation is worth considering, especially for education, workforce development, nonprofit capacity or civic pride.
  • Priority goes to projects serving Penobscot, Piscataquis and Aroostook counties, and half of its grants to organisations were $39,000 or less, so a modest request fits best, although its stated range runs from $5,000 to $250,000 and the filings show one award of $485,000 above that maximum.
  • Start with the Initial Grant Application, which opens each January and is due by 1 March; selected applicants then complete a Final Grant Application by 30 June, and the Foundation may ask for a presentation or facility tour and quarterly status reports if funded.
  • Build the case around innovation, long-term impact, essential community services, organisational capacity and collaboration with town, state or national partners, since repeat funding also matters: 20% of grant dollars went to organisations it had funded in earlier filings.
  • Organisations that are not US tax-exempt public charities or political subdivisions, or whose work does not benefit Maine residents, are not eligible.
