Roopam Garg, chief executive officer, dentsu X, has put in his papers at the organisation.
While Garg has stepped down from his role at dentsu X, the network is looking to retain him by offering him a different role, according to sources.
Garg was elevated as CEO in September 2021, after Divya Karani was handed a wider South Asia role.
He joined dentsu in 2017. He has also worked with MEC, ZenithOptimedia London, Publicis Groupe Media Vietnam and Starcom China.
