T-Engine is Topsort's intelligent ad engine for commerce media. It powers real-time auctions, pacing, ranking, quality scoring, attribution-aware optimization, and full-funnel ad decisioning for retailers, marketplaces, and commerce platforms.
An ad server mainly delivers ads. T-Engine decides which ads should win, how budgets should pace, how quality and relevance should affect ranking, and how ad decisions should optimize for revenue, advertiser performance, and commerce outcomes.
Use T-Zero when you need lightweight, programmable ad serving. Use T-Engine when you need intelligent decisioning: pacing, quality scoring, attribution, optimization, relevance, and full-funnel performance controls.
Most ad servers were built to deliver ads. Modern retail media needs more than delivery.
Commerce companies need to decide which ads deserve to appear in high-intent moments, how budgets should pace, how relevance and quality should affect ranking, how to protect customer experience, and how to optimize for both retailer revenue and advertiser outcomes.
That is the job of an intelligent ad engine.
T-Engine turns ad serving into commerce-aware decisioning.
Run commerce-native auctions that balance bid, relevance, placement, budget, and business logic in milliseconds.
Control how advertiser budgets are spent over time so campaigns do not burn too fast or under-deliver.
Use quality and relevance signals to protect customer experience and improve long-term advertiser performance.
Connect ad decisions to downstream outcomes such as clicks, conversions, attributed purchases, and revenue.
Rank ads using commerce context like query, category, product, seller, placement, availability, and shopper intent.
Improve revenue without reducing marketplace quality or advertiser trust.
Optimize across impression, click, conversion, purchase, and revenue outcomes instead of treating ad serving as a one-step delivery event.
T-Engine evaluates every commerce media opportunity through a decisioning layer that combines eligibility, auction mechanics, pacing, quality, relevance, and performance signals.
