Angela Ahrendts

Apple’s highest-ranking female exec continues the consumer tech giant’s epic quest to convert its brick-and-mortar stores into destinations. Ahrendts, who joined the board of Ralph Lauren this year, leads about 67,000 people, and her retail business, while not Apple’s fastest-growing, remains huge: eMarketer estimates that combined in-store and online sales are about $74.3 billion. Ahrendts has also been instrumental in expanding Apple’s reach in China, which now counts more than 40 stores.
