19. Gregg Ambulos
SVP, Global Channel Sales
When you've been managing channels for the same vendor for 15 years, you're not just doing something right, you're a leader in the industry. In his push to drive EMC's channel business and help it adapt to changing markets, Gregg Ambulos rolled out a variety of changes to EMC's program earlier this year, helping make it more profitable and easier to navigate. His efforts haven't gone unnoticed, and it appears he'll also have a significant role in the combined Dell-EMC.
