St. Louis native and Twitter co-founder Jack Dorsey will take over as interim CEO of the social media company when Dick Costolo steps down from his role as Twitter’s chief executive on July 1, the company announced Thursday.
Dorsey will serve as CEO until the Twitter board of directors determines a permanent replacement for Costolo, the company’s leader since 2010. Costolo faced mounting pressure as Twitter continued to lose money and saw its stock price tumble by close to 50 percent after peaking in January 2014.
This will be Dorsey’s second stint as the CEO of Twitter, the platform that lets users share 140-character posts. He led the San Francisco-based company until 2008, when he was forced out and replaced by co-founder Evan Williams.

While Dorsey serves as Twitter’s interim CEO, he will continue in his role as chief executive of Square, the mobile payments company he co-founded.
Dorsey, who is currently Twitter’s executive chairman, graduated from Bishop DuBourg High School in St. Louis and attended the Missouri University of Science and Technology — formerly the University of Missouri-Rolla — before attending New York University.
