Seb Rennie has returned to Australia to take up his old role as GroupM chief investment officer after three years in Canada.

Rennie departed the local holding group in 2017 to take up the same role in GroupM Canada. During his time there, he has oversaw the introduction of GroupM’s new Investment management technology and the launch of the group’s addressable TV business Finecast and out-of-home business Kinetic.

In his new role, his responsibilities include leading GroupM’s local Investment & Partnership function, and maximising the performance of the group’s media agencies.

“Seb is well-known and well-respected in the Australian media marketplace and perfectly placed to take on this high-profile role at the forefront of driving industry change, best practice and business growth,” says GroupM APAC CEO Ashutosh Srivastava.

“Seb is a world class operator in Investment and Partnerships, with strong relationships across Australian media, and a global perspective.

“We are pleased to welcome him back to the region for the next phase of his career with GroupM, after a successful and productive three years driving value for our clients in Canada.”

Rennie will relocate to Sydney and begin his new role in June.

“I’m over the moon to be returning to Australia and taking up a leadership position with GroupM as the business transforms around a clear vision to be responsible for shaping the next era of media where advertising works better for people,” Rennie says.

“”It’s been a real pleasure to work with Stuart Garvie and the Canada team and our media partners to deliver clients unrivalled competitive advantage. I’m eager to get back to Australia and join the team to help enable the ongoing evolution of investment across GroupM’s agencies and products.”

The return of Rennie comes following key appointments at GroupM, including the departure of chief digital strategy officer Venessa Hunt last year, CEO Mark Lollback in March, and the appointment of Willie Pang to GroupM Services managing director.

Rennie will work closely with Claire Butterworth who has been interim general manager of investment at GroupM since February.
