Joe Belfiore

Corporate Vice President, Windows Phone Program Management & Design
Microsoft

As the key exec for Microsoft's Windows Phone Program, Joe Belfiore focuses on usability and overall experience of Microsoft's mobile technology products. Belfiore now faces the daunting challenge of establishing the Windows Phone 7 and future iterations as a leader in a very crowded mobile space. It is a huge come-from-way-way-behind challenge for Microsoft. Before moving to the Windows Phone team, the 20-year-old company veteran–who came to Microsoft fresh out of Stanford University–has been in charge of the Zune Software and Services, as well as the "eHome" Division of Windows.
