Topsort Developer Day brings together the brightest minds in Retail Media to tackle the toughest challenges in ad monetization and chart a course for the industry’s future. We're hosting it where it all began, in the heart of Silicon Valley.
Four years ago, we asked if technology could solve Retail Media’s biggest hurdles. We found our answer: by coming together, we can. Join us as we break down Big Tech’s barriers and put product-driven innovation into the hands of the builders.
