The Global Impact Investing Network was conceived in October 2007, when the Rockefeller Foundation gathered a small group of investors to discuss the needs of the emergent impact investing industry.
In June 2008, a broader group of 40 investors from around the world met to discuss what it would take for the impact investing industry to be able to solve more social and environmental challenges with greater efficiency. They organized behind a number of initiatives, including the creation of a global network of leading impact investors, the development of a standardized framework for assessing social and environmental impact, and a development of a working group of investors focused on sustainable agriculture in sub-Saharan Africa.
Just over a year later, the GIIN was formally constituted as an independent organization. These three initiatives formed the first projects of the new organization.
