Siri co-founder and CEO Dag Kittlaus apparently left Apple following the launch of the iPhone 4S. Word of his departure comes courtesy of unnamed sources who claim the move was in the works for some time.
Mr. Kittlaus was said to have left Apple on good terms, according to AllThingsD, and that he wanted more time to pursue new business ideas and to be with his family in Chicago.
Apple purchased Siri in early 2010, bringing the voice control app maker under its wing. Apple then expanded Siri’s functionality and rolled it into the iPhone 4S as a spoken word command system that lets users talk conversationally to their phone.
It also looks like Mr. Kittlaus’s departure isn’t the beginning of a Siri exodus from Apple. Instead, other executives that came along with the Siri purchase are planning on staying with Apple.
Apple hasn’t yet commented on the report of Mr. Kittlaus’s departure.
