Your nonprofit must be registered for #GivingTuesday on Mightycause to be eligible for prizes. This year, Mightycause and the Mightycause Charitable Foundation are investing in nonprofits for GivingTuesday. Serving nonprofits and helping them grow is just what we do. And that's why we're offering $20,000 in GivingTuesday cash prizes to help nonprofits raise money, engage supporters, and advance their causes beyond December 1st.
