Neil Blumenthal and Dave Gilboa started Warby Parker as a business school project in 2010. The premise was simple: shake up the old-line optical business by selling frames online, and at a lower price than traditional retail. Today, Warby Parker is one of the biggest players in optical, a robust online business leveraging e-commerce but with a growing retail footprint of some 250 stores as well. On this episode of Leadership Next, Michal talks to Neil and Dave about Warby Parker's founding story, changing consumer behavior, and how to remain innovative as a company matures beyond startup mode. Leadership Next is powered by Deloitte.
