About us

About GEO:

Grantmakers for Effective Organizations is a coalition of grantmakers committed to building strong and effective nonprofit organizations. Understanding that grantmakers are successful only to the extent that their grantees achieve meaningful results, GEO promotes strategies and practices that contribute to grantee success.

GEO provides philanthropy's change agents with the resources, ideas and connections they need to make the greatest contribution to the nonprofits they invest in. GEO does this by:

  • commissioning and contributing to research,
  • developing programs and products, and
  • building a community of practice that expands the resources available on nonprofit effectiveness.

Currently, GEO has approximately 3,000 individual members representing more than 400 grantmaking organizations. For more information about GEO, visit

About the Scaling What Works Initiative:

Launched in 2010, Scaling What Works is a multiyear learning initiative of Grantmakers for Effective Organizations to expand the number of grantmakers and public sector funders that are working together to broaden the impact of high-performing nonprofits. In 2012, GEO's Scaling What Works initiative helped private and public sector funders advance the conversation about their role in scaling impact. Activities included: a national workshop series to build the financial assessment and evaluation capacity of grantmakers in philanthropically underserved areas. Publications and webinars on learning communities and supporting nonprofit talent, publications to share early lessons learned from the social innovation fund, meetings with intermediaries of the social innovation fund and communication efforts to advance the notion of scale as growing impact.
