Martin is assuming the top spot at Reprise from Maex, who had been Reprise’s Global CEO since 2019, while Martin was previously Global Chief Operating Officer at Initiative. The two executives share a background as longtime Mediabrands leaders with a depth of expertise in data- and performance-marketing capabilities at Mediabrands:

“In Dimitri, we have a seasoned global leader who has turned Reprise into a performance marketing powerhouse, and he will bring that experience to Initiative to enhance its already powerful product in the marketplace benefiting clients and teams alike,” said Daryl Lee, Global CEO of Mediabrands. “Jarrod will be equally transformative as he applies his AI and analytics expertise to accelerate the depth and power of our precision digital and e-commerce solutions.”

Lee continued: “Plus, what is more satisfying than promoting next generation leaders from within. Both Dimitri and Jarrod exemplify Mediabrands’ deep bench of talent who were born and raised in a data-rich world.”

Under Maex’s leadership at Reprise, the specialist agency has grown substantially by simplifying capabilities and integrating around clients. Maex merged the search and social departments into integrated performance marketing teams dedicated to clients and aligned to the core global brands of Initiative and UM. He launched Reprise Commerce and grew that practice into a leading global capability with a full suite of solutions for global clients. He scaled the performance marketing content capabilities of Reprise by building out key hubs around the world.

“Performance marketing is no longer a subset of a marketing strategy, it needs to be the core of any integrated marketing strategy,” said Maex. “I am excited to be asked to lead Initiative, an industry leader in media craft and cultural creativity, through its next chapter as we look to enhance the performance of all media. And I look forward to working closely with Jarrod as we build integrated teams for our clients.”

Over the last five years at Initiative, Martin turned his passion for data and insights into a competitive advantage for the award-winning global agency. He has been a champion of building new service models for clients across core data functions of digital reporting, analytics, and optimization. Martin’s career at Mediabrands began in 2013 where he started a specialist analytics unit in Australia, later moving to New York, becoming Global President of Mediabrands Insights before joining Initiative.

“I am absolutely thrilled to be joining Reprise,” said Martin. “During my time at Initiative, I frequently collaborated with my colleagues there as we built out Initiative’s suite of analytic services, so it is incredibly gratifying to now work with them from the inside to accelerate the shift to more AI-driven solutions for our clients.”

It’s not the first time Maex and Martin crossed paths as they both worked at OgilvyOne in London 20 years ago, a time they call the “go-go years”.

Earlier this week, it was announced that Maex would become Global CEO at Initiative, succeeding Amy Armstrong, who is leaving Initiative to join one of the agency’s long-standing clients, Amazon. Armstrong, whose 25-year career at IPG included five years in top leadership roles at Initiative, will become Director of Global Client Development at Amazon Ads.
