The Global Impact Investing Network (GIIN) is a non-profit membership organization that supports the growth of impact investing, a field in which financial institutions and individuals invest their money for social and environmental impact. Researchers used Neo4j graph databases to visualize GIIN members' food and agriculture investments, revealing connections and potential opportunities for entrepreneurs, investors, and network managers. The graphs show overlap between GIIN members' portfolios, as well as co-investments with non-GIIN members, which could lead to new revenue streams for GIIN. However, the research is limited by publicly available data and caveats such as missing investment portfolios and sparse information on co-investors. Despite these limitations, Neo4j enabled the researchers to take initial steps in exploring impact investing networks and providing tools for entrepreneurs and network managers.
