At the end of 2010, Michael Dubin was working in marketing when he met a guy named Mark Levine at a holiday party. Mark was looking for ideas to get rid of a massive pile of razors he had sitting in a California warehouse. Michael's spontaneous idea for an internet razor subscription service grew into Dollar Shave Club, and his background in improv helped him make a viral video to generate buzz for the new brand. Just five years after launch, Unilever acquired Dollar Shave Club for a reported $1 billion. Recorded live in Los Angeles.
