What it does: Management consulting and training. Why it's growing: Back in 2001, CEO Al Switzler and his three partners decided to promote their business by writing a bestseller. Which is exactly what they did. Crucial Conversations: Tools for Talking When Stakes Are High landed on The New York Times business bestseller list and was followed by a sequel. "Those two books are now in 17 languages," says Switzler, and they serve as the basis for training materials that VitalSmarts sells through resellers around the world.
