John is the Chief Product and Marketing Officer for Podium. Prior to that he was CPO for Mailchimp. And prior to that he was one of those annoying consultants who would come into your company and tell you to do things that were good ideas maybe half the time.

John has a graduate degree in operations research from MIT, so his first book, Data Smart, was about machine learning. Then he forgot all that stuff as he got older and wrote a second book about just like plain business stuff.
