Acclaimed management guru Jason Jennings and his research team screened more than 100,000 companies to find nine that have increased revenues and profits by 10% or more for 10 consecutive years. After interviewing the leaders, workers and customers of these quiet superstars, they discovered that these companies all have one thing in common; they think big but act small. These companies are highly ambitious about solving customers' problems. Yet they never stop acting like start-ups, treating every employee like an owner and teaching managers to get stuck in.
