Your Support is Needed—Membership Dues Cover Less Than 50% of Operating Costs

Our success depends on the generous support of foundations, individuals, and corporate partners.

Our flat and modest dues structure is unique in the philanthropy sector. We are committed to our founders’ belief that membership dues should not be a roadblock to greater impact.

Contributions and grants allow us to serve as a responsive and valuable resource for lean funders. Every contribution, no matter the size, helps us realize our vision of transformed communities through informed giving.

“We give to Exponent because they have helped me so much with my journey, ultimately affecting this foundation.”
