A Diverse Landscape
of Impact Fund Managers

Now in its fourteenth year, the ImpactAssets 50™ is the most recognized free database of impact investment fund managers. This annually updated list is a gateway into the world of impact investing for investors, financial advisors and philanthropists. The IA 50 offers an easy way to identify experienced and emerging impact fund managers and is intended to illustrate the breadth of impact fund managers operating today. Fund managers selected to the IA 50 demonstrate a wide range of impact investing activities across geographies, sectors and asset classes.

Launch Database

The IA 50 is not an index or investable platform and does not constitute an offering or solicitation to buy or sell securities or a private placement, or recommend specific products. Nor is this an endorsement of any of the listed fund managers. It is not a replacement for due diligence.

The IA 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.

The IA 50 2025 Impact Fund Managers

We’re proud to spotlight impact fund managers across three distinct categories.

Our Selection Process

To compile our annual list of fund managers, ImpactAssets assembles an annual Review Committee of experienced, respected impact investment leaders.

The IA 50 Review Committee selects 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. Particular consideration will be given to firms that demonstrate a unique strategy, under-represented impact theme and leadership diversity in view of application pool.
