Funder intelligence

The foundation consistently prioritizes long-term, systemic change and evidence-based solutions, with an increasing emphasis on equity and justice across all program areas. While national in scope, their funding supports a diverse range of organizations including universities, research institutions, and advocacy non-profits, often without strict geographic restrictions for their broader initiatives.

The Heising-Simons Foundation primarily operates by invitation or requires a Letter of Inquiry (LOI) following initial engagement, generally not accepting unsolicited proposals. Relationship-building is a critical component of their grantmaking process.
