Oscar Ekponimo

Rolex Young Laureate, 2016

Oscar Ekponimo, of Nigeria, is solving an old problem – malnutrition caused by poverty – with a 21st century invention. His cloud-based app, Chowberry, alerts retailers when products reach the end of shelf life. Discounted food can then be offered to relief agencies, cutting waste. Ekponimo, who suffered from hunger as a child, developed his app to help the millions of Nigerians who do not get enough to eat.
