Erik Hersman is an innovator, technologist, and blogger focused on the use of technology to empower people in the developing world. He founded Ushahidi, a non-profit that uses crowdsourcing as a model for social activism and public accountability. Ushahidi’s work helped inspire the term ‘activist mapping’ – a hybrid practice that combines social activism, citizen journalism, and geospatial information mapping. His latest venture is BRCK, a rugged internet that brings service to rural locations in Africa.
