When she was in her 20s, Maya Ajmera founded The Global Fund for Children. The nonprofit invests in innovative organizations working with some of the world’s most vulnerable children. She says scaling an organization doesn’t always mean scaling out. Sometimes it can be down (serving more in the community) or up (advocating for your idea on a wider stage.) Her latest book is called Invisible Children: Reimagining International Development at the Grassroots. She speaks with Kelly Brownell.
