Chief design officer, PepsiCo

The dapper Italian started a new gig this summer at PepsiCo as the company's first chief design officer. Trailblazing a role at a Fortune 500 enterprise is nothing new for Porcini. Prior to PepsiCo, he spent 10 years at 3M, where he started as a design manager and worked his way up to become the company's first chief design officer. The self-described change agent evangelizes for the incorporation of design principles into all of an organization's processes -- something he'll do from his powerful perch at PepsiCo to drive growth and innovation.

Clotheshorse: Porcini owns 90 pairs of shoes and 30 watches.
