From Creators to CTV: Building a $2B Ad Business – Jesús Moreno Sosa, Mercado Ads

S3 E25 · Sep 21, 2026 · 36 min

Tom and Todd spend a lot of time talking to retail media networks in the US. Somehow, they missed a $2 billion ad business in Latin America.

Show notes

Jesús Moreno Sosa joins The Middlemen to explain what Mercado Ads has built: its own DSP, an affiliate network that operates like a media channel, and advertising connected to Mercado Libre’s commerce and Mercado Pago’s payments infrastructure.

The sellers get simple products to buy. The enterprise advertisers get full-funnel capabilities, including streaming partnerships with Disney+, HBO Max and Roku. And the technology connects those campaigns to what people actually purchase.

A lot of our conversations are about what’s holding retail media back. This one is about what happens when you connect the pieces.
