By now, we’re all aware of the dark side of the world of finance. But there’s another side to finance that starts with a youthful impulse to save the world and evolves into something both savvy and humane. After a funny encounter with a child wearing her cast-off sweater in Rwanda, Jacqueline Novogratz realized how interconnected the world really is. Novogratz has been at the front of a movement that combines social investing and social entrepreneurship in some of the poorest countries in the world. She is founder of The Acumen Fund, a nonprofit venture capital firm that supports small businesses in developing countries, and author of the book The Blue Sweater: Bridging the Gap between Rich and Poor in an Interconnected World.
