Guy Kawasaki's first job after he completed his psychology degree at Stanford was counting diamonds. He's been counting them ever since. He worked at Apple when it was a diamond in the rough, returned when it first lost its gleam, and as the company's chief evangelist helped to give it new polish.
He has invested in or advised a stream of successful businesses Evernote, Ustream, and Microsoft's Motorola division, and built and run several successful technology companies. He sits on the board of Wikimedia, and he now spends much of his time traveling and talking to audiences to help them find their own diamonds. Recently he has been working and advising as Chief evangelist at Canva.
As well as his undoubted expertise and unique way of leveraging the power of social media, his Keynotes, talks and lectures on Startups and Entrepreneurship are not to be missed.
