Richard William "Dick" Costolo (pronounced: /ˈkɒstəloʊ/) was the CEO of Twitter from 2010 to 2015; he also served as the COO before becoming CEO. He took over as CEO from Evan Williams in October 2010. On June 11, 2015, it was announced that Costolo would step down as CEO on July 1, 2015 and would be replaced by Twitter co-founder and chairman Jack Dorsey on an interim basis until the Board of Directors could find a replacement. On August 8, 2015, The New York Times reported that Costolo would be leaving Twitter's Board of Directors by the end of the year or when a new CEO is appointed.
Costolo graduated in 1985 with a B.S. degree in computer and communication sciences from the University of Michigan. Costolo became involved in theater during his senior year at the University of Michigan, when he began taking theater classes to fulfill the university's graduation requirements. Upon graduation, he decided not to accept offers from technology companies and instead moved to Chicago to work in improvisational comedy. Costolo used to perform with Chicago's Annoyance Theater and at various comedy festivals in other places.
After his improv career in Chicago, Costolo was at Andersen Consulting for 8 years, where he was a senior manager in product and technology groups. He then co-founded Burning Door Networked Media, a web design and development consulting company, which was acquired by Digital Knowledge Assets in October 1996. He then co-founded SpyOnIt, a web page monitoring service, which was sold to 724 Solutions in September 2000.
