Slavi Samardzija, Global Chair of Media and Commerce at Stagwell, distinguishes the platform from legacy systems by noting it was purpose-built for modern workflows rather than having AI layered onto existing infrastructure. "The difference is that legacy platforms were built for them to perform legacy tasks, and then they're layering AI on top of that," Samardzija said.2
The agency leverages solutions from The Marketing Cloud and Stagwell Media Platform, including Stagwell Search+ and Stagwell Curate, alongside advanced data and commerce capabilities.

Stagwell Media's approach extends beyond technology to encompass multidisciplinary talent capable of delivering integrated solutions. Samardzija highlighted how the agency's practitioners demonstrate expertise across multiple disciplines: "I was working with a client leader, a role equivalent to an account person at a legacy agency, and this person developed an audience strategy and a media plan that was equivalent to that of a data scientist."

Rutgersson emphasized that performance must encompass more than media buying. "It has to be about the customer experience. It has to be about the integration that technology can provide between media and creative," she stated.

The agency will continue partnering with sister companies within Stagwell's Media and Commerce segment, including Crispin, GALE, Goodstuff, Locaria, and Stagwell Owned Media, to deliver connected solutions that drive business results.1
Connie Chan, who serves dual roles as Chief Growth Officer for Stagwell APAC and CEO of Stagwell Media APAC, noted regional pressures driving demand for the new model. "Across APAC, brands are facing increasing pressure to move faster and deliver measurable business outcomes," Chan said, adding that clients increasingly seek partners combining specialist expertise, integrated capabilities, and deep local market understanding.

The launch signals Stagwell's ambition to challenge established agency holding companies by offering what it positions as a superior combination of deep expertise, connected capabilities, and practitioner-centric technology. As brands navigate an evolving marketplace where agentic systems increasingly shape discovery, recommendation, and activation, Stagwell Media's integrated model aims to help clients adapt faster and unlock stronger business performance across every platform.
