Jason Harrison started as a 23-year-old account executive at Ogilvy & Mather before moving to London five years later to run three agency teams in three different European countries. He joined his old mates again in 2011 as one of the founding partners of the M&C Saatchi Group at 33. He believes that creating beautifully simple solutions for an increasingly complex world will, in fact, save the world. “The Suit” is about inspiring and helping up and coming suits to be better at their craft. He is no longer on Twitter.
