Elevating User Experiences With AI
Sebastian Barrios, SVP of technology at Mercado Libre, an Argentine-founded online marketplace, is focused on an approach toward agentic AI — using AI copilots and agents to execute customer service tasks without human supervision (except for instances of high-value tasks or when the decision is not clear).
Within that, his team has been working on catalog cleanup and improved product listings to elevate the search user experience.
“You talk about search — that's another huge one where semantic understanding, and then leading into what we're calling a personalized shopping assistant experience, is delivering a lot of value for our users,” he said.
Expanding efforts is a challenge, however, as an impressive pilot might draw significant results, but not with great enough accuracy (99% or 100%) to achieve scalability.
In order to avoid risks associated with following the shiny object, Barrios said the company has been very diligent about building an internal platform that closely analyzes pilots and asks the necessary questions: “How are we going to protect data? How are we going to make sure customer data is not leaked between sessions or that only the most relevant information is there for the model?”
Barrios predicts that 2025 will be the year of seeing proper value extracted from AI solutions — transformational use cases in areas like customer service and search assistance.
“The honest truth is that the technology is revolutionary, but it hasn't transformed any business dramatically,” he said. “There are marginal improvements, and that's not bad, but if we can increase conversion by 2% here or 3% there, that obviously adds a lot of value to the business.”
