Naren joined Primesight in 1991. He floated the business on the London Stock Exchange in 1997 to become one of the youngest Managing Directors of a listed company. He continued to build out the business and in 1999 sold Primesight to SMG plc (now STV plc).

This was followed up in 2009, with the acquisition of Titan’s (previously Maiden Outdoor) billboard portfolio. In 2016 Primesight moved into the airport advertising sector after securing the advertising right with Manchester Airport Group and then acquiring Airport Media Group.
