Diversify beyond grants with recurring, unrestricted support
Researching funders is smart — but grants are competitive and slow. Good Circles builds a base of recurring, unrestricted funding alongside your grant strategy: supporters pick your cause once, then a share of their everyday local spending funds you automatically — about 10% of each merchant's net profit, conservatively ~$72 per active supporter per year (an estimate), free for your nonprofit. Good Circles launches in the South first (September 2026).
