Resources created and curated to support the growth of impact investing, for those new to the field and for experienced practitioners.

ImpactAssets 50 

This annually updated list is a gateway into the world of impact investing for investors and their financial advisors, offering an easy way to identify experienced impact investment firms and explore the landscape of potential investment options. The ImpactAssets 50 is intended to illustrate the breadth of impact investment fund managers operating today, though it is not a comprehensive list. These 50 firms have been selected to demonstrate a wide range of impact investing activities across geographies, sectors and asset classes.




The ImpactAssets 50 is not an index or an investable platform; rather, it is an information resource to begin research on the impact investing sector.

The ImpactAssets 50 is focused on private debt and equity fund managers to provide a centralized source of information that is not publicly available elsewhere. However, investing for impact can be done across many asset classes and we encourage investors to make use of other resources (US SIF, The GIIN) in evaluating sustainable, responsible, impact investing options.



Inclusion in the ImpactAssets 50

The application period to become an ImpactAssets 50 2019 fund manager is now closed. Applications for the ImpactAssets 50 2020 will open in October 2019.
