Who
We Are

In the 20 years since the Dalberg Group’s creation, the firm has worked on nearly every social impact issue imaginable with a wide variety of partners. Through this work, it became clear that we had a unique vantage point and set of skills that we could leverage to more proactively address some of the world’s most pressing problems.

Dalberg Catalyst was thus born. We are a small and nimble team and our dedication to the issues we work on is matched only by our ability to build cross-sectoral coalitions to achieve meaningful progress.

Our Story

Our
Supporters

While originally set up by the Dalberg Trust with a seed investment in 2020, Dalberg Catalyst functions as an independent entity and is funded entirely by donors. We rely on the support of like-minded partners who share our values and are excited to fund the kind of agenda-shaping work not being done anywhere else.
 

We also benefit from the contributions of global citizens like you. Your support can help us prevent the next pandemic, increase vaccine equity, and pave the way for a forest-friendly economy.
