13. Oscar Rodriguez
Since joining Extreme Networks in August 2010, Rodriguez has shored up the company's finances and bolstered its channel programs. In July 2011, he cut about 110 jobs, or 16 percent of its global workforce, to save operating costs. Extreme has rebounded with new programs, including a global partner advisory council with 14 members, and has pushed into the data center, BYOD and the education spaces.
