Almost exactly a year ago, Google announced a couple of leadership changes that saw Prabhakar Raghavan, who joined the company back in 2012, take over the lead of Search, Assistant and Maps. Now, sources familiar with the hiring tell us, the company has hired Christopher Phillips, who was previously the chief product and technology officer at SiriusXM, to lead its geo team, which is responsible for products like Google Maps, Google Earth and Google Maps Platform, the company's enterprise business around these products. Google has confirmed his hire but declined to share any additional information.
