Tim Cook

CEO, Apple

Even before taking the reins as the head of Apple, replacing its late legendary co-founder Steve Jobs, Cook was responsible for the company’s worldwide sales and operations, including end-to-end management of Apple’s supply chain, sales activities and service and support in all markets and countries. Prior to joining Apple, he was VP of Corporate Materials at Compaq, COO of the Reseller Division at Intelligent Electronics and director of North American Fulfillment at IBM, where he led manufacturing and distribution functions for IBM’s PC Company. Ah, sweet irony.
