The Center for Effective Philanthropy works closely with Grantmakers for Effective Organizations (GEO) on issues of foundation effectiveness. For example, GEO's Premium Members receive a five percent discount on CEP's assessment tools and GEO is a co-sponsor of CEP's Foundation Governance Project.

GEO is a community of grantmakers dedicated to building strong and effective organizations. GEO’s mission is to maximize philanthropy’s impact by advancing the effectiveness of grantmakers and their grantees. Through research, conferences, its Web site, publications and other activities, GEO highlights knowledge and practices in the field that advance the organizational effectiveness movement. More information about GEO and a host of resources and links for funders are available at www.geofunders.org.

The Center for Effective Philanthropy is a content partner with the National Center for Family Philanthropy's Family Philanthropy Online Knowledge Center.
