WHO WE ARE Since our start more than three decades ago in a townhouse in Washington, D.C. we have helped thousands of communities, NGOs, governments, media organizations and individuals solve complex development challenges, often in areas torn apart by hunger, conflict and violence. OUR MISSION We are driven by our desire to solve some of the world’s most pressing challenges affecting those less fortunate across the developing world. We undertake our work with a commitment to diversity, equity and inclusion both at home and in the countries where we work. OUR STORY “We step towards today’s complex and challenging problems facing government, communities and businesses - working closely with our partners to develop new ideas and tools, and to deliver smart and lasting solutions.” Keith Brown President OUR LEADERSHIP As a leadership team, we love what we do and the people that we work with!
