Former Chicagoan Cheryl Rosner has stepped down as chief executive of online deals site BuyWithMe after less than a year in her position.

New York-based BuyWithMe said Wednesday that Jim Crowley, the former CEO of Turbine Inc., has taken the helm. A BuyWithMe spokeswoman said Rosner and the company mutually decided to part ways and she remains on the firm’s advisory board. Rosner will be spending more time with her family, the spokeswoman said.

Rosner had joined BuyWithMe in April 2010 after a stint as CEO at Rolling Meadows-based TicketsNow, which was acquired by Ticketmaster in January 2008. In July, shortly after Rosner joined BuyWithMe, the company raised $16 million from investors. BuyWithMe officially launched in Chicago in October, competing with other daily deal companies such as Groupon, YouSwoop and LivingSocial.

Turbine Inc. is an online gaming studio that was acquired by Warner Bros. Entertainment in April 2010.
