About

The Case Foundation developed the Impact Investing Network Map, with data partners Impact Space and CrunchBase, to present the best publicly available data on impact investments to better inform the sector. We believe that bringing the connections between investors and companies to life will foster a better understanding of the size, breadth and depth of the impact investing ecosystem. Since launching the Impact Investing Network Map, we have gathered feedback from many users and have repeatedly heard interest in applying the visualization and lessons learned to other projects and sources of data.

We are excited to announce that we are open sourcing the code of the Impact Investing Network Map, for others to repurpose and reimagine our product for their own new projects. The code powering the relationship map visualization, filtering options and insights section will be open and free to use on the Case Foundation's GitHub account, as the *Relationship Map Visualization. While the basis of our original Impact Investing Network Map was to display historical direct investments made into companies by investors using publicly available data, with the open source *Relationship Map Visualization, users can

• apply their own dataset for projects like visualizing local impact investment activity;
• update the code with new functions, filters, and visualization features; or
• even apply the code for a purpose outside of Impact Investing.
