Duff is a journalist and author of several books. His first book, The CEO, a Choose Your Own Adventure, was co-written with his friend Owen Burke. He also co-authored his latest, Frictionless, with another friend, Christiane Lemieux. When deciding to do the podcast, the obvious co-host choice was Duff’s long-time friend, Matt McButter. The lesson here? Everything is more fun when you do it with your friends. Duff lives in upstate New York, on a mountain.
