Philanthropy's primary funding strategy -- restricted grants -- too often hamstrings grantees' ability to plan, invest, and respond to changes with vision, flexibility, and innovation. Since its inception, the F.B. Heron Foundation has primarily made core support grants. We believe that core support promotes effectiveness, innovation, leverage, and transparency among our grantees, as well as more candor between grantee and grantor. In this essay, we add our voice to the ongoing dialogue about a better balance between core support and restricted grants.
