MIAMI — Monks — the global, digital‑first operating brand of S4 Capital — has appointed Paula Marsilli as Vice President, Regional Accounts for Latin America. Reporting to Sebastián Caramés, EVP LatAm, Marsilli will lead the strategic orchestration for key accounts, tasked with helping these marketers navigate the shift to an AI-first marketing supply chain.

A Brazilian leader based in Miami since 2024, Marsilli brings over 20 years of experience in media and growth across Brazil, Mexico, and the United States. She joins Monks at a pivotal moment to deploy blended intelligence—integrating senior human talent with AI-driven workflows to collapse timelines and drive business impact.

As VP at Monks LatAm, Marsilli’s mandate moves beyond traditional client service. She is charged with building real-time brand ecosystems for clients, ensuring these accounts can move from making assets to making decisions at speed.

Her priorities include:

  • Orchestration: Breaking down silos between data, media, and creative to build “systems of scale” that operate in real-time.
  • Decision Augmentation: Implementing outcome-based models where AI handles the execution scale, allowing teams to focus on high-value strategic impact.
  • Cross-Border Scalability: Leveraging Miami as a strategic hub to operationalize Machine Availability—ensuring brand visibility in the algorithmic marketplaces of LatAm.

“Working with key accounts in the LatAm region requires more than just traditional agency support; it requires a partner who understands the algorithmic geography of the modern feed,” said Paula Marsilli. “Monks is the only player building a true operating system for this new era. My goal is to use our talent & machine model to help these clients stop compromising between speed and quality, ensuring they can carve out their place in culture while hitting their commercial targets in real-time.”

“Paula’s appointment reflects a shift in how we serve our most advanced clients,” said Sebastián Caramés, EVP LatAm. “In the post-agency era, clients don’t just need people to manage hours; they need leaders who can orchestrate complex, AI-enabled systems. Paula is the definition of the ‘T-shaped talent’ we are prioritizing—someone who can bridge high-tech efficiency with high-touch human strategy. She brings the operational rigor we need to raise the standard of delivery for our strategic accounts.”

“Building a real-time brand means having the voice of the customer available in every decision and responding to trends in minutes, without a punitive commercial model,” said Bruno Lambertini, CEO of Monks, Marketing Services. “Paula understands that delivering this for clients requires more than traditional account management; it requires orchestrating a system of scale. Her leadership will empower our talent to operate at this new velocity, bridging high-tech efficiency with true cultural relevance

Marsilli has held senior roles at major agencies and advertisers, including Natura, Uber, VMLY&R, Omnicom Media Group, McCann, and Ogilvy & Mather. A Caboré Award winner and former IAB Brazil director, she has spent her career at the intersection of commerce and creativity. This background positions her to lead large-scale accounts that demand strong data foundations and AI-enabled media orchestration.
