Charles is chair of Apps for Good and the Nominet Trust, as well as a senior associate at Nesta.
Charles spoke about his latest book The Frugal Innovator, which looks at a wave of innovators from Latin America, Asia and Africa, who are responding to the tight constraints and a lack of resources by devising low cost solutions to pressing social challenges which are lean, simple, clean and social.
The Frugal Innovator argues these solutions, the people, organisations and methods that produce them will become more vital in both the developed and developing world in future.
