Join Impact 100 Greater Indianapolis

Impact 100 has been an important part of the Indianapolis community since 2006, along with our annual goal of delivering more than $100,000 to nonprofits in the Greater Indianapolis community. Through our grants we have proven that collective giving works, and that a group of inspired women can accomplish much more than any one of us can alone.

The annual membership fee is $1000. Up to four women can join together in a Shared Membership to pay the $1000 membership fee.
