Description of Stanford Entrepreneurship Video: Accenture’s Liz Tinkham interviews salesforce.com’s Polly Sumner about entrepreneurship that occurs in both large and small companies. They both agree that innovation and risk-taking occur in any-sized company where the culture emphasizes “no idea is a dumb idea.” Sumner advises young entrepreneurs to not fear risk: every failure teaches you a valuable lesson, and once learned, success is that much sweeter.
