Twitter CEO Steps Down, But Stays At Company

Evan Williams announced today via the Twitter blog that he is stepping down as CEO after 2 years at the helm. His new title will simply be co-founder, and he’ll be focusing on product strategy.

Williams has replaced himself with Twitter COO Dick Costolo. Says Williams:

When I insisted on bringing Dick into the COO role a year ago, I got a lot of questions from my board. But I knew Dick would be a strong complement to me, and this has proven to be the case. During his year at Twitter, he has been a critical leader in devising and executing our revenue efforts, while simultaneously and effectively making the trains run on time in the office.

Costolo has a strong track record in tech profitability – he has founded and sold multiple online ventures, most notably web feed management provider Feedburner, which Google purchased in 2007 for around $100 million.
