Kelly Clark, global chief executive of WPP’s GroupM, will take on his responsibilities while the company searches for a replacement.

Lesser took on the role of GroupM North America chief executive two years ago. He’d previously served as global chief executive of Xaxis.

“Brian has been a key contributor to 24/7, Xaxis and most recently GroupM, and we are sorry to see him go, but wish him every success in his new role,” GroupM said in a statement.

According to the Wall Street Journal, Lesser will be tasked with “building an advertising and analytics business using the company’s customer data and content assets” at AT&T.
