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 firms have been selected to demonstrate a wide range of impact investing activities across geographies, sectors and asset classes.

Announcing the IA 50 2020!

We’re pleased to share this year’s list of IA 50 2020 fund managers.

New for 2020: IA 50 Emerging Impact Manager Category

As the field matures we don’t want to lose sight of innovative new entrants. The Emerging Impact Manager category is intended to spotlight newer fund managers that may demonstrate future potential to create meaningful impact. Criteria such as minimum track record or minimum assets under management may not be applicable.


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 2021 Fund Manager will open in October 2020. To stay informed on the application process, sign up here.

The ImpactAssets 50 Review Committee finalizes firms according to a set of criteria developed to ensure that the list includes a diverse set of firms with experience in the field, scale in terms of AUM and investor base, commitment to impact and representing a range of approaches, asset classes and impact areas.
