Robin Chase, Founder & CEO, Buzzcar talks with Joel Makower, Chairman & Executive Editor, GreenBiz Group about the evolution of the shared economy. Chase was founder of Zipcar, widely regarded as one of the best examples of collaborative consumption. With Buzzcar, Chase is taking the concept a step further, relying on members to share their excess vehicle capacities amongst each other, as opposed to the centralized fleet of Zipcar. This enables the model to spread much more quickly, with a less capital intensive structure.
