Membership Info

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 most important aspects of the Impact 100 model are:

  • The Power of the Collective – By bringing together at least 100 women, each giving $1,000, we have a more profound impact on our community.
  • One Membership = One Vote – Every Impact 100 Greater Indianapolis member has a vote in deciding where the money goes.
  • Shared Memberships – Two to four women can pool their money to share a membership. Women in a Shared Membership have all the rights of a Full member except they share the membership’s one vote at the annual meeting.
  • Choose Your Level of Involvement – The only membership requirement is to donate and participate in the vote at our annual meeting. But you can take your involvement further and serve on one of our committees simply by letting us know you’re interested.
  • 100% of Member Donations Go to Grant Recipients and Are Given Away Each Year – One hundred percent of member donations received one year are returned to the community in the form of grants the next year. Membership donations must be made before December 31st of one calendar year to be part of the grant pool awarded the following calendar year. For example, a membership donation made in 2024 goes into the 2025 Grant Pool.

More About Shared Memberships

While the greatest impact comes from each woman donating $1000, Impact 100 Greater Indianapolis offers Shared Membership (Syndicate) memberships. A Shared Membership allows 2-4 women to pool their money and share a membership. Each Shared Member has full membership rights (serving on committees, attending events, etc.) with the exception of the women in a Shared Membership may cast only one vote at the Annual Dinner, and must agree on how that vote is to be cast.

Before considering a Shared Membership, we would encourage you to review your annual donations and weigh the difference between the multiple organizations you support against making the commitment to help Impact 100 fund a transformational grant, and the opportunity to see your donation have an impact on our community.

Shared Memberships can be made up of family members (sisters, mother/daughter, aunt/niece, etc.), friends, co-workers, or any group of 2-4 women who want to join without the full commitment.

We can also help you find other women to create a Shared Membership.
