Head of GM’s Maven Unit Leaves

Julia Steyn, who has headed General Motors Co.’s Maven urban mobility business since it was created three years ago, has left the company for unknown reasons.

Media reports say her departure, which is still being finalized, is not part of GM’s plan to reduce its salaried staff by 15%.

Steyn joined GM in 2012 to direct mergers and acquisitions. She was put in charge of the company’s urban mobility activities in 2015. Her departure follows that of Peter Kosak, who had been executive director of urban mobility, last February.

Maven debuted as an on-demand service for cars rented by the hour or day. The unit later expanded into peer-to-peer car sharing for GM vehicles, and again to allow drivers who don’t own a car to rent Maven vehicles for their own use or to deliver packages or groceries.
