My fourth book, Sharkonomics (about strategies for attacking market leaders), will be published in March 2012.

You are swimming with sharks and you may not even know it. Stefan is your guide to not only surviving Sharkonomics but thriving in these adventurous economic waters.
Brian Solis, author of The End of Business as Usual and Engage!
