As a part of my series about “Big Ideas That Might Change The World In The Next Few Years” I had the pleasure of interviewing Todd Greene. Todd is the CEO and co-founder of PubNub, an Internet infrastructure company that delivers realtime technology into the apps and products you use everyday. Todd started his career as a management consultant at PwC, and soon after, transitioned to the world of Silicon Valley startups. With a focus on unlocking new markets with Internet-based software, Todd has found success launching and leading companies delivering business, consumer, and tech infrastructure products.

Prior to that, Todd founded CascadeWorks (now part of NASDAQ: UPWK), which invented a new way for large companies to onboard and manage their consultants.
