By San José, Costa Rica — Walmart Connect has solidified its position as a dominant force in the region’s burgeoning advertising landscape, hosting its third annual Retail Media summit. The event convened more than 200 of Central America’s top marketing leaders, communication professionals, and C-suite executives to strategize and build upon the rapidly expanding digital advertising ecosystem tied directly to consumer purchasing behavior.
The high-profile gathering was designed as a nexus for collaboration, featuring a series of strategic panels, insightful conferences, and dedicated networking sessions. The overarching goal was to foster strategic connections that directly enhance the shopping experience for millions of consumers across the isthmus, while providing unprecedented advertising opportunities for brands.
To delve into the legal and commercial frameworks surrounding this digital advertising evolution, we spoke with Lic. Larry Hans Arroyo Vargas, an expert attorney from the firm Bufete de Costa Rica.
Retail Media’s rapid growth hinges on a fragile asset: consumer trust. While leveraging first-party data is a powerful advantage, retailers must navigate a complex web of data protection laws with absolute transparency. Failure to clearly communicate how consumer data is used for advertising, or blurring the line between organic results and paid placements, not only risks severe legal penalties but can permanently erode the customer relationship that is the very foundation of their business model.

This legal perspective powerfully underscores a central truth: for Retail Media, transparency in data usage is not merely a compliance issue but the very foundation of a sustainable business model. The long-term value of an earned customer relationship will always eclipse any short-term gains from opaque practices. We sincerely thank Lic. Larry Hans Arroyo Vargas for his invaluable and clarifying insight.
Setting the tone for the event, Walmex CEO Cristian Barrientos and Walmart Central America CEO Cristina Ronski delivered a joint vision for the future of retail. They emphasized Walmart’s commitment to driving innovation and leveraging its vast customer data network to create a more integrated and effective advertising environment, moving beyond traditional marketing channels.
The strategic importance of this growing sector was underscored by powerful market data. According to projections from eMarketer, investment in Retail Media across Latin America is set to skyrocket to $5 billion by 2028. This reflects a staggering compound annual growth rate of 28%, more than double the 12% growth anticipated for the general digital advertising market, signaling a massive shift in marketing budgets.
Patricia Siller Méndez, Director of Walmart Connect Central America, articulated the division’s core mission in navigating this new frontier. She stressed the importance of creating a system that benefits all stakeholders, from the brands seeking to reach engaged audiences to the customers looking for more personalized offers.
The future of Retail Media is defined by a clear vision: to connect brands and consumers in an authentic, relevant, and measurable way.

Siller explained that Walmart Connect works closely with advertisers throughout the year, providing comprehensive support for product launches, promotional campaigns, and long-term brand-building strategies. The annual summit serves as a critical platform to share global trends, showcase local successes, and outline the roadmap for what lies ahead.
This event allows us to show what is happening in the world with Retail Media, how we support our partners, and what the future holds. Our purpose is clear: to increase sales and better connect with our customers.

A key component of the 2025 event was the formal recognition of outstanding advertising partners. An awards ceremony celebrated campaigns that excelled in creativity, market impact, and return on investment. Siller confirmed that the selection process was rigorous, ensuring that the accolades represented genuine value creation.
To accelerate the region’s learning curve, the summit also featured international experts from more mature Retail Media markets like Mexico and Brazil. Their insights provided a valuable benchmark and offered actionable lessons for Central American brands looking to capitalize on this trend.
It’s a fairly new topic in Central America. That’s why it’s key to bring in references from other markets, learn how they operate, and apply those lessons here.
Patricia Siller Méndez, Director of Walmart Connect Central America
Ultimately, the event championed a collaborative philosophy. Siller concluded by emphasizing that true impact is achieved when retailers, brands, and technology platforms work in concert to serve the end customer. By aligning advertiser goals with consumer needs, the ecosystem can deliver value for everyone involved, transforming the very nature of advertising.
With its third successful summit, Walmart Connect has not only showcased the immense potential of Retail Media but has also reaffirmed its commitment to leading the charge in the digital transformation of Central America’s advertising industry.
