Support Impact100 Philadelphia
Sponsorship investments in Impact100 Philadelphia sustain our work and strengthen our organization. While most of our annual financial needs are met by our members’ operating donations, additional financial support builds our capacity to engage more women philanthropists, grow our membership, and expand our grantmaking. Your gift ensures that Impact100 Philadelphia can further enrich the communities we serve and supports the work of our members as civically engaged leaders, volunteers, and advocates for nonprofits.
Why invest in women’s collective giving and support Impact100 Philadelphia with a gift?
- A 2018 study supported by Indiana University’s Women’s Philanthropy Institute found that donors who give collectively are more active, informed, and strategic philanthropists than their non-collective giving peers.
- A 2023 comprehensive analysis of collective giving in the United States expanded on the 2018 study, finding that women’s collective giving groups practice trust-based philanthropy, elevate women’s leadership and connections, and give additional support through all five T’s — talent, testimony ties, time, and treasure – to nonprofits in their communities.
- Year over year, our annual membership survey illuminates similar findings. 60% of our members report learning more about the nonprofits in our region because of their membership, and 43% have made additional donations to grant recipients beyond their Impact100 membership donation. Involvement in Impact100 Philadelphia expands our members’ knowledge as well as their financial support of our region’s nonprofit community.
