Global Impact Investing Network (GIIN)

The Global Impact Investing Network (GIIN) is a long-standing organization that houses the IRIS+ metrics sets. In addition to the IRIS+ indicator list, the GIIN houses numerous resources on how to operationalize IMM and how different frameworks (such as the Impact Management Project) map onto the IRIS+ method.  While the GIIN’s resources are designed primarily for impact investors, their methods can be applied to any organization.
