AKQA Group CEO Ajaz Ahmed, who founded the agency in 1994 and has been its chief executive for 30 years, has resigned, parent company WPP announced on Thursday.

A successor has not been named, WPP said in a statement. In the interim, AKQA Group will be led by the existing leadership team at AKQA and sister agency Grey, with “WPP Chief Technology Officer Stephan Pretorius overseeing the business in the role of interim chair,” according to the statement. WPP acquired AKQA in 2012. 

It’s unclear what’s next for Ahmed. He has been focused on charitable work and sits on boards including the Elton John AIDS Foundation, Virgin Unite (founded by Richard Branson) and Mission 44 (founded by Lewis Hamilton).

“Serving AKQA’s team, clients and values over the past 30 years has been the greatest honor of my life,” Ahmed said in a statement. “Founding AKQA at a young age was the start of an incredible journey, and if destiny allows, I look forward to another 30 years of meaningful work and making a difference. I’m tremendously energised about the adventures ahead and the opportunity to do something new.” 

Ahmed was 21 when he founded AKQA. He’s seen the shop through various changes including its merger with sister creative agency Grey in 2020, which formed AKQA Group.

“Under Ajaz’s leadership AKQA has become one of the world’s most recognized and highly regarded agencies,”WPP CEO Mark Read said in a statement. “It’s a brilliant business with many extremely talented people around the world. With its exceptional global team, capabilities and expertise, AKQA is well-positioned for continued success and we thank Ajaz for his vision and contribution to the business.”
