Modern Commerce Ad Server
T-Zero gives teams a lightweight way to launch commerce ad serving. But if your retail media business needs pacing, quality scoring, attribution, relevance controls, yield optimization, and full-funnel performance, start with T-Engine intelligent ad engine.
T-Zero is a modern commerce ad server from Topsort. It helps marketplaces, retailers, and commerce platforms serve ads, run auctions, control ranking logic, and monetize sponsored placements through programmable APIs.
Yes. T-Zero can be used as a modern ad server for commerce use cases. Unlike legacy publisher ad servers, T-Zero is built for retail media, marketplaces, sponsored listings, auction-based monetization, and product-led advertising experiences.
Use T-Zero when you need lightweight, programmable ad serving. Use T-Engine when you need intelligent decisioning, including pacing, quality scoring, attribution-aware optimization, relevance controls, and full-funnel performance.
A commerce ad server is ad serving infrastructure designed for marketplaces, retailers, delivery apps, travel platforms, financial platforms, and other commerce businesses. Unlike publisher ad servers, commerce ad servers need to understand products, sellers, placements, transactions, availability, relevance, and purchase outcomes.
T-Zero gives commerce teams this foundation without forcing them into a heavy legacy adtech stack.
For advanced pacing, quality score, attribution-aware optimization, and performance decisioning, use T-Engine.
Most ad servers were built for publishers, impressions, and display placements. Commerce is different — teams need ad serving inside product discovery, search, listings, category pages, and custom monetization surfaces.
T-Zero is built for commerce logic first. T-Engine adds the intelligence layer when commerce media needs to optimize, not just serve.
T-Zero is designed for teams that need programmable ad serving across commerce experiences, not one-size-fits-all publisher inventory.
Serve and rank sponsored products, services, sellers, or listings inside search and browse results.
Monetize seller, vendor, and partner demand with sponsored placements built directly into marketplace experiences.
Launch retail media ad serving without adopting a heavy legacy adtech stack.
Create custom sponsored placements that match your product experience and commerce UX.
Serve commerce-aware display placements where simple, fast delivery matters.
Power custom ranking, promotion, or monetization logic without building ad server infrastructure from scratch.
If your team is evaluating ad servers, T-Zero belongs in the RFP when speed, control, APIs, commerce use cases, and auction transparency matter.
T-Zero is designed for product and engineering teams embedding monetization into commerce experiences. Use clean APIs, predictable responses, flexible schemas, sandbox environments, and decision-level logs to launch fast while staying in control.
