CEO North America, Accenture, 50
Sweet’s North America business, which accounts for roughly half of Accenture’s revenue, edged up nearly 4% in 2017, to $16.3 billion. The company is pushing aggressively into digital, cloud, and security services (Accenture calls the trio “the New”); they now account for about half of her region’s business. Investors seem to like the tech focus: The stock is up 27% over the past 12 months. Sweet is also investing in her people—Accenture has trained 60% of its North American workforce in new IT this year.
