For more information about Impact 100, including the difference between a Full and a Shared Membership, please go to our Membership Information page.

Join

Joining is as easy as clicking one of these links:

  • Join and make your membership donation at the same time: (credit card or ACH bank transfer):
  • Set up a Make a Membership Pledge to make your membership donation later and/or use a donation method other than a credit card or ACH bank transfer. You can see all the methods of payment we accept on our Donation Methods page.
  • Please review our Recurring Donation page to understand the process to set up a Recurring Donation.

Membership donations must be made before December 31st of a calendar year to be part of the grant pool awarded the following calendar year (the 2025 Grant Pool is closed, donations in 2025 go to the 2026 Grant Pool). Contact us at joinus@impact100indy.org if you have any questions.

Please use the Comments field on these forms to provide us with additional information, such as the names of people you want in your Shared Membership, if you are making a donation to pay for someone else’s membership, or if you want your donation split between multiple people or purposes.

Donate

Anyone, including members and alumnae, can provide additional support to Impact 100 in many ways, listed below.

  • Give to our Leaders of the Future Program providing Impact 100 memberships to women at the beginning of their philanthropy-related careers (click here for more information on the program).
  • Donate to our Grant Pool: The form will ask you to make a designation for your donation, but you can enter information in the Comments field if you want your donation split between several options. A donation directly to the Grant Pool does not provide a vote on who receives our Change Maker Grant.
  • Pay for the membership for a family member, employee, or other woman using the Full Membership or Shared Membership form. Please enter the name of the recipient for your donated membership along with their email and/or other contact information along with any other information you wish to share in the Comments on the form.
  • Make a donation to help cover operating costs. Since100% of our membership and grant pool donations go into our grants, we depend on our donations to our Administrative Fund to help cover our operational costs, including credit card fees and the support of this website. 
  • Give While Shopping! Sign up for Kroger Rewards (or use your existing account) and select Impact 100 as your Community Rewards designee. Each time you shop at Kroger a percentage of your purchases are donated back to Impact 100 when you use your Kroger Rewards card.

*The links above require payment by credit card, but Impact 100 accepts all methods of payments, from a personal check to a donation of stock. Please use our Non-Membership Pledge form to let us know you plan to make a donation using one of other Donation Methods, or use our printable Impact 100 Print Donation Form. Please be sure to add any notes regarding your donation and its purpose to these forms.
