Publicis Marcel Gets a CEO as Agentic AI Drives Growth

Publicis Marcel, the internal AI platform Publicis Groupe launched in 2017, now has its own CEO and chief strategy officer and will be run more like a standalone business. The move signals that agentic AI, meaning AI agents that complete multistep tasks on their own, sits at the center of the holding company's growth plans (Marketing Dive, as of October 26, 2026).

Who leads Marcel, and what will it build?

Scott Hagedorn becomes CEO of Marcel and Sam Levine Archer becomes chief strategy officer. Both came to Publicis from rival Omnicom, where they helped run the media division, and have led AI solutions work at Publicis for the past four years.

Growth area	Group assets Marcel draws on
Influencer and creator marketing	Publicis Sapient (technology and consulting)
Sports and culture marketing	Epsilon (customer data)
Optimizing for AI chatbot answers	Lotame (consumer profiles)
Data connectivity	LiveRamp, a $2.2 billion acquisition being finalized

When it bought Lotame, Publicis said it gained a view into nearly 4 billion consumer profiles, about 91% of internet-connected consumers worldwide. Marcel is meant to connect that data into AI agents built for clients.

Why give an AI tool its own executives now?

Marcel was widely mocked when it was unveiled, but it now looks like an early bet on AI's role in marketing. Publicis reported 5% organic net revenue growth in the third quarter of 2026, ahead of most peers. CEO Arthur Sadoun said that while competitors cut headcount and investment, Publicis is doing the opposite: strengthening teams and doubling down on data and technology.

Demand is uneven, though. Agentic services are busy, while large enterprise-wide AI transformations are slower because they are costly and time-intensive. The Sapient-led technology unit remained sluggish in Q3.

Takeaways for marketers

1. Ask what data an agency's AI connects to, not just whether it uses AI. The same tool produces very different results depending on the customer and consumer data behind it.
2. Check data neutrality. When a holding company buys a data provider, access terms for rival agencies and advertisers can change. We covered those terms in LiveRamp neutrality: five-year rules and buyer trust.
3. Start with small agentic tasks. Hand AI agents clearly scoped work such as reporting, creative variations or bid adjustments, and measure the results before attempting a full transformation.
4. Read it alongside the wider consolidation. The competitive picture is clearer next to Omnicom IPG integration: what advertisers should check.

Independent agencies like ours face the same question from clients. Our answer is to start with small automations tied directly to client data and prove them with results.
