GroupM agency Wavemaker has appointed Toby Jenner Global CEO. Jenner joins from sibling agency MediaCom, where he was most recently Worldwide Chief Operations Officer. 

Earlier, he was MediaCom’s Global Chief Business Development and Marketing Officer, Asia-Pacific Chief Operating Officer and CEO of Australasia. He originally joined GroupM as managing director of MEC in the U.K.  

Jenner succeeds Tim Castree who was named GroupM’s North American CEO in December. 

Jenner will lead Wavemaker’s 8,600 employees who manage $13 billion in billings, according to COMvergence, for clients in 90 countries. 

Jenner will begin his new role in September and report to Kelly Clark, GroupM’s Global CEO.

“Toby has been an outstanding contributor to our group’s growth for more than 15 years,” stated Clark. “In his 11 years at MediaCom, he’s been instrumental in delivery of breakthrough client work, a winning streak on award circuits regionally and globally, and powerful business development performance.”

Wavemaker was formed in 2017 when WPP combined two existing GroupM media agencies: MEC and Maxus.

Since then, the combined entity has invested in new capabilities in precision marketing, commerce and content marketing. The agency claims to have won 67% of its pitches, with more than 300 new clients joining the agency’s roster during that time.
