EVP, HP Personal Systems Group
One in every five PCs sold today is made by Hewlett-Packard, and that's largely thanks to Todd Bradley. He was CEO Mark Hurd's first major hire when Hurd took the reins from Carly Fiorina in 2005. Within a year, Bradley, 49, launched the celebrity-packed "The computer is personal again" ad campaign, recruited designers like Vivienne Tam, and outsold Dell to become the largest PC maker. Under his leadership, HP's $42 billion personal systems group, which also includes mobile devices, workstations, and Internet services, has increased profitability by 300%.
With 28 years' experience in management, Bradley has proved his ability to help struggling businesses turn around. As CEO of PalmOne (which later became Palm), he shifted the company from PDAs to smartphones, and he cleared up the supply-chain issues that nearly crippled the company. Bradley now believes that HP's future lies in mobile devices; to jump-start that strategy, he's turning to (you guessed it) Palm, which HP acquired for $1.2 billion this spring.
The guy definitely has brainpower, but don't take our word for it. Ask other savvy executives, including Motorola co-CEO Sanjay Jha, who regularly seek his counsel. --J.H.
