We had a fun chat with Derek Johnson, the CEO of start-up Tatango.  Derek was recently chosen as one of the ” 2009 Finalists: America’s Best Young Entrepreneurs” by Business Week.  Derek has led Tatango through many phases since it’s inception.  In this interview we discuss proper communication to customers & investors, how and how not to implement changes with your business, and when & why to make certain changes.  Tatango just recently switched from an ad based service to paid subscriptions, this is no easy feat.  Listen to the interview and let us know what you think.

Can we rely on ad based business models any longer?

What type of businesses should charge a subscription and what types shouldn’t?  Is there a method or is it a crapshoot?
