A chief executive had a dilemma. After working in a fast-growing company as COO, he accepted an offer from venture capitalists to start his own company. Within five years he had built a new enterprise generating revenues over $300 million and profit margins so high that his company had compiled a substantial cash reserve with which it was poised to go on an acquisition run. His passion, strategic and analytical brilliance, and relentless focus on practical results made him a rare, virtually unstoppable force in industry.
