What is Topsort?
Topsort is an AI-native, API-first commerce infrastructure company based in Silicon Valley. Its T-Engine auction layer, ad-server APIs and optimization tools let marketplaces and retailers stand up sponsored listings, display, native, video and offsite ads quickly, with closed-loop online attribution. It works with 100+ retailers across 40+ countries, including Coles, Woolworths, DoorDash and Falabella.
Topsort is genuinely strong where it focuses. It is API-first by design, cookieless and privacy-respecting, fast through an edge-deployed auction engine, and it recently launched Sponsored Prompts, an agentic ad format for conversational commerce. It is backed by W23 Global, a fund formed by five leading grocers including Ahold Delhaize and Tesco.
What Topsort provides is infrastructure: the auction engine and APIs a retailer builds its ad business on. The retailer brings its own data and builds audiences, insights, in-store media and operations on top. This page does not argue Topsort is weak. It argues that Footprints AI starts somewhere different, with the physical store, shopper behavior and SKU and store-level sales proof, delivered as a complete platform.

What is Footprints AI?
Most retail sales still happen in the store. Physical stores accounted for roughly 84% of US retail sales in Q3 2025 (US Census Bureau), and that majority is the spend an online auction engine does not measure. It is where Footprints AI starts.
Footprints AI is a next-generation retail media platform built first for the physical store, then extended across online and off-site. It treats in-store as a first-class, measured channel: screens, audio, shelf and POS are planned, targeted by real shopper behavior, and connected back to sales. The platform spans five modules, Campaigns, Audiences, Sales & Shopper Insights, In-Store Measurement and Leads, so a retailer runs the whole operation in one place rather than stitching point tools together.
Where Topsort provides the auction engine a retailer plugs in, Footprints AI provides the whole operation: audiences from 100% shopper transaction behavior, in-store media, shopper and category insights, and closed-loop SKU and store-level measurement that isolates incremental sales with test and control. The operating promise is simple: 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, and it is deployed as a white-label, multi-tenant platform a retailer owns, in-store and online.
