Ritas Rainbows is a 501(c)3 grantmaking organization that operates on a relationship-based model, exclusively providing grants by invitation. This funder does not accept unsolicited proposals, making it essential for nonprofits to explore warm-introduction pathways through Impala's Funder Prospecting to engage with their grantmaking opportunities.
