Groupon Co-Founder Eric Lefkofsky Interviewed By Thinkorswim Co-Founder Tom Sosnoff on TastyTrade

I watched Tom Sosnoff, co-founder of online brokerage firm Thinkorswim (bought by TD Ameritrade in January 2009 for $606 million), speak about entrepreneurship and selling opportunities at the Chicago TechWeek Conference on Friday online (goes on until Tuesday). He now runs the financial media company TastyTrade, and I saw that he interviewed Groupon and LightBank co-founder Eric Lefkofsky on June 13. Watch the videos below.
