Maria Grivas is the new CEO of Reprise Australia, Mediabrands’ digitally-led full-service performance agency.

Grivas is currently chief data and technology officer at UM Australia. Mediabrands CEO Mark Coad described her as the "ideal future leader" for the business.

“I’m thrilled that Mediabrands has talent of Maria’s calibre to promote into such an important leadership position, also that we have her high-quality team members in place to continue their work. We will look to replace Maria’s role as UM’s chief data and technology officer in due course, but after very special consideration for this key role.”

Reprise Australia employs some 150 people across Sydney, Melbourne, Brisbane and Perth, working on both group accounts and its own independent clients.

In taking the leadership role at Reprise, Grivas will also join the Mediabrands Australia Executive Leadership Team.

“Having already worked closely with Reprise for some time, I am very excited about the CEO role," she said. "The business has a large team of very talented people doing great work. My ambition is to help elevate their successes as the industry evolves at pace.”

Grivas replaces previous CEO Matt Sallis, who has resigned for family reasons related to travel restrictions from his base in Canada.

“Matt has done a great job under very difficult circumstances," said Coad. "We wish him the very best for the future.”
