Daniel Isenberg is an entrepreneur, venture capitalist and academic, whose interest in what makes an entrepreneur has led him to study examples (both successes and failures) across the globe. In his book Worthless, Impossible and Stupid, Daniel makes the point that entrepreneurs are “contrarian value creators.” They see value where others see nothing. And he isn’t afraid to point out that it is profit that so often drives ideas. It’s about changing the world and the monetizing of ideas. Facebook is a multi-billion dollar company. It doesn’t need to be. But it is.
