Who
We Are

Over the past two decades since Dalberg was established, our group of mission-led enterprises has partnered with and served communities, governments, foundations, non-profits, multilaterals and companies to build a more sustainable and inclusive world.  Through this work, it became clear that our unique perspectives, skills, and decades of experience, expertise, and relationships could be extended to build broader solutions that proactively address some of the world’s most important and urgent challenges through systemic change.

Dalberg Catalyst aims to bring to life a portfolio of new solutions and multi-stakeholder initiatives to meet this goal. While we are independent from the businesses in the Dalberg Group, we build upon 20 years of Dalberg’s expertise, knowledge, networks, and skills to proactively and co-creatively shape, design and deliver solutions from start to finish.

Our Story

Our
Supporters

Originally set up by the Dalberg Trust – the non-profit custodian of the Dalberg mission – with an innovation grant in 2020, Dalberg Catalyst functions as an independent entity funded entirely by donors. This allows us to take on a more proactive role in identifying and bringing to life multi-stakeholder solutions to address some of the world’s most pressing problems. We rely on the support of like-minded partners who share our values and are excited to create agenda-shaping, collaborative action that leads to meaningful, systemic, and lasting changes in the world.

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.
