Publicis Groupe appoints Scott Hagedorn as first CEO of Marcel to expand its AI solutions

New leadership to expand Marcel

Publicis Groupe has appointed Scott Hagedorn as the first CEO of Marcel, its AI-based activation platform, and Sam Levine Archer as Strategy Director. Both will assume their new roles while retaining their current responsibilities within the group: Hagedorn as Chief Solutions Architect and Levine Archer as Chief Solutions Officer.

The team will oversee 400 people across various markets and expand Marcel's offerings in areas such as creator and influencer marketing, sports, culture, content intelligence, and AI-assisted search and discovery. The company presents this change as an evolution from task automation to agentic solutions designed to detect opportunities and contribute to client growth.

Hagedorn joined Publicis in 2022, coming from Omnicom. According to the company, he and Levine Archer have participated in its data and artificial intelligence transformation over the past four years.

From connecting employees to creating agents for clients

Launched in 2017 as a platform to connect the people, knowledge, and capabilities of Publicis, Marcel has evolved to also become a tool for developing AI agents. Publicis states that the platform is already used in projects for more than 90 clients and that it gathers thousands of agentic skills created by its professionals.

The expansion will rely on the capabilities of Publicis Sapient, Epsilon, and Lotame. The proposal involves combining enterprise, consumer, and marketing data with human experience to design tools adapted to each business. Publicis maintains that clients will retain ownership and control of their data.

The approach aims to differentiate Marcel from general-purpose AI assistants. It does not involve abandoning large models: the platform can direct each task to the model it deems most suitable, rather than being tied to a single provider. The company claims that the agents first rely on data and knowledge specific to the client and Publicis, although the available information does not detail how this criterion will be applied in all cases.

The bet: moving from operational efficiency to growth

The announced strategy aims for AI to do more than just accelerate existing processes. Publicis wants the agents to help identify business opportunities, guide decisions, and activate initiatives across different channels. Among the areas mentioned are creator marketing, sports, and live experiences, as well as tools for AI-driven discovery and commerce.

Carla Serrano, Global Strategy Director at Publicis Groupe, described the next step as creating new sources of growth, rather than as a way to make workflows faster. Hagedorn, for his part, stated that the value of an agent depends on what it knows, how it reasons, and what results it can offer. These are objectives and assessments from management; the announcement does not provide metrics on business results attributable to the new structure.

For interested companies, the proposal also has a practical condition: Publicis has indicated that organizations need to have sufficiently mature data and AI frameworks capable of integrating with Marcel. The company has not published a single rate; according to ADWEEK coverage, the cost varies depending on the agentic development required by each client. Therefore, the appointment expands the commercial ambition of the platform, but it does not imply that all organizations are equally prepared to adopt it, nor that the price or scope will be uniform.
