In my last piece, The Creative Revolution: Why AI Has Killed the Excuse for Boring Marketing, I argued that AI has fundamentally changed how many ideas make it to the table. The cost of bringing a bold concept to life has dropped far enough that teams no longer have to pre-filter the experimental or "out there" bets. But speed and volume of options only matter if the ideas are pointed at something real.
Most creative briefs are built on demographic assumptions. Age range, income bracket, observed shopping habits, or general lifestyle assumptions. It's a starting point, but it's also a ceiling. You end up designing for a composite that doesn't quite match anyone, and the work feels generic because it is.
Starting with behavior, not assumptions
As a Publicis agency, we have access to Epsilon's PeopleCloud, which tracks behavioral data across 255 million people, across 7,000 attributes, updated three times a day. Not survey data, where people describe who they aspire to be. Purchase behavior. Subscription patterns. Actual decisions people made with their own money.
That distinction matters more than it might seem. While survey data is vital for understanding attitudinal motivations (the "why" behind a choice), it is most powerful when paired with behavioral data. Survey data tells you how people feel; behavioral data tells you what they actually do. When you pair the two (with a dash of real-time insights sourced from the web), you get a complete picture of who someone is and what moves them. When you build creative strategy on that combined foundation, the work tends to land differently.
We might find, for instance, that a meaningful segment of mountain bike buyers also has a strong affinity for boutique coffee and weekend woodworking. That's not a connection a standard brief would surface. But once you see it, it opens up creative directions that feel earned and specific rather than broadly demographic. You're not guessing at a lifestyle. You're reflecting one.
From segments to AI Personas
Once we identify those behavioral clusters, our Strategy and Creative Teams leverage AI persona agents: detailed profiles drawn from real-world data that our teams consult during ideation and concepting. The distinction from a traditional persona is important. These aren't archetypes assembled from flat demographic sketches and gut feelings. They're grounded in how real people actually spend their time and money, which means when you pressure-test a creative idea against them, the feedback is more useful.
Rather than asking "would our target audience respond to this?" you're asking something more specific: Would this resonate with someone whose purchase behavior looks like this, whose lifestyle clusters like that? It's a harder question, and a more honest one.
Paired with Synthetic Focus Groups, we can get quick, early directional feedback on bold concepts in hours rather than weeks, before any meaningful budget is committed. This combination—behavioral data informing the brief, AI Personas shaping the ideation, and Synthetic Focus Groups stress-testing the output—enables us to bring bolder, validated concepts to the table for leadership review significantly faster. It gives the C-suite a credible foundation to evaluate before they are asked to scale a campaign.
Your leadership wants a credible path to ROI before they commit real dollars? Build the proof first. Show them the audience insight behind the idea, the early validation. Then ask for the budget to scale what worked.
The tools to do that exist now. The data is there. What's left is mostly the willingness to bring the bold options to the table in the first place.
