Uncharted Play

With a degree in economics from Harvard already under her belt and an M.B.A. in progress, Jessica Matthews seems primed for Wall Street. However, she's used her business expertise to found Uncharted Play , a social enterprise that uses technology and playful activities to help solve real-world issues. One example is SOCCKET, a soccer ball that converts light into energy while you play. The sales from SOCCKET help provide children in need with reliable energy access.
