Paul Polak, a Pop!Tech 2008 featured speaker, has been starting businesses since he was 15. He’s now 75, and says he has succeeded — and failed — with more ventures than he can count. Polak’s first was a strawberry distribution operation in his hometown of Millgrove, Ontario. Later Polak prospected in real estate and oil and made millions. In 1981, he invested the proceeds into a nonprofit incubator of sorts called International Development Enterprises.
