Membership Benefits Sustaining Membership

Sustaining Members are organizations guiding the way for foundations and others in the impact investing field through innovation and pioneering new practices. By joining at this annual membership level of $16,500 to $100,000, foundations express their support of MIE's role in growing a movement committed to deep impact.

Sustaining Members receive all of the foundation member benefits described on the adjacent tab and are recognized on the MIE website and in member lists, given opportunities to feature case examples and news stories, and have a direct link with MIE staff to coordinate the sharing of press releases, investment stories, and other impact investing content.
