Peter Bell

Peter fell in love with startups after spending 10 years as an early employee at EMC, where he experienced firsthand how the right product, business model and innovation can kill a market incumbent. Ever since, he’s been solely working as or with entrepreneurs – he lives for the ambiguity of writing vs. executing a business playbook, and his role as a venture capitalist allows him to work alongside the brightest minds in technology.

Peter focuses on companies in the information security, e-commerce, cloud infrastructure, mobile, enterprise software and communications industries. In his role as a sounding board to entrepreneurs, Peter helps prioritize growth objectives, build teams and create product-market fit. He likes to focus on go-to-market strategies that ensure category leadership.
