Acumen Fund. Acumen Fund is a non-profit global venture fund that uses entrepreneurial approaches to solve the problems of global poverty. We seek to prove that small amounts of philanthropic capital, combined with large doses of business acumen, can build thriving enterprises that serve vast numbers of the poor. Our investments focus on delivering affordable, critical goods and services – like health, water, housing and energy – through innovative, market-oriented approaches. www.acumendfund.org. Jacqueline's inspirational and innovative story is told in her book The Blue Sweater.
