Dick Costolo

Dick Costolo is a co-founder and General Partner at 01 Advisors, a $920M venture firm he built with former Twitter COO Adam Bain. Before that, he was the CEO of Twitter from 2010 to 2015 - the longest-tenured and most financially productive CEO in the company's history, growing revenue from zero to $1.5 billion and leading its 2013 IPO. He started his career as an improv comedian at Chicago's Second City (Steve Carell was in his cohort), built and sold three startups including FeedBurner to Google for ~$100M, and remains one of the most candid, self-deprecating, and operationally sharp executives in Silicon Valley.
