What is Unlimitail?
Unlimitail is a retail media joint venture between Carrefour and Publicis, operating as a sales house and network across Europe and Latin America. It is built on the CitrusAd and Epsilon technology stack and Carrefour Links shopper data, drawing on 8B+ transactions and 80M+ customers, with 13+ retail partners and off-site reach through DOOH and CTV partners such as JCDecaux and M6.
Unlimitail's value is regional scale and a managed sales house: brands buy coordinated on-site, off-site and DOOH campaigns across Carrefour and partner retailers, measured against Carrefour's shopper data.
Unlimitail is strong regionally, but it is one retail group's sales house running a licensed stack, not a platform other retailers deploy and own. Its in-store reach is largely DOOH and identity-matched activation, and its data centers on Carrefour. Notably, Footprints AI campaign evidence from a Carrefour Romania programme showed stronger incremental-sales outcomes than the CitrusAd and Unlimitail stack. Footprints AI is a platform any retailer owns.

What is Footprints AI?
In-store is the next major retail media frontier, with 2026 a critical inflection point, according to the research firm Coresight. The question for every retailer is whether to join one group's sales house or own its own network.
Footprints AI is a next-generation retail media platform built first for the physical store. It treats in-store as a first-class, measured channel across screens, audio, POS, shelf and Wi-Fi, then extends across on-site and off-site. The platform spans five modules, Campaigns, Audiences, Sales & Shopper Insights, In-Store Measurement and Leads, so the retailer runs the whole operation in one place.
Where Unlimitail is one retail group's sales house built on a licensed stack, Footprints AI is a platform any retailer deploys and owns, physical-store-first, with audiences from 100% shopper behavior and closed-loop SKU and store-level proof, with Footprints AI campaign evidence showing stronger incremental-sales outcomes than the same CitrusAd/Unlimitail stack in a Carrefour Romania programme. The operating promise: buy true reach, pay per view, get real sales attribution.
It operates at scale across 30+ retailers, 65 agencies, 550+ brands and 50M+ shoppers, tracking 5B+ shopping trips and 7,000+ campaigns, deployed as a white-label, multi-tenant platform a retailer owns, in-store and online.
