While AI headlines often chase shiny creative tools, Dentsu is focusing the spotlight on media planning. Through a partnership with startup Evidenza, the agency network is bringing synthetic audiences—AI-generated personas built from real but anonymized data—into the center of campaign planning and targeting. Unlike traditional panels, these digital twins are created quickly from probabilistic data, allowing planners to test, adapt, and activate strategies at speed, all without depending on personal information.
To feed the AI’s appetite, Dentsu is combining insights from its own Consumer Connection System panel with Evidenza’s data sources. Early results suggest this isn’t just a gimmick. According to Dentsu’s chief data officer, the AI-built audiences show an 87% similarity to legacy population analyses, reportedly offering faster turnaround and increased precision. In a world where budgets need to stretch further and decisions need to come faster, Dentsu sees this trend as the new planning muscle, not just an experiment in automation.
This partnership is part of what may be a broader strategy at Dentsu: favoring alliances over acquisitions. Alongside Evidenza, the company also locked in deals with MiQ and Criteo, suggesting it’s less about owning the tech and more about playing nice with the right players.
