Developed from their experiences at Google, Google Ventures, and now Character Capital, the Foundation Sprint guides teams through identifying their target customer, key problem, competitive landscape, differentiation strategy, and optimal approach path. The framework creates an explicit founding hypothesis that can be tested through subsequent Design Sprints.
