The mind
behind the
machine.
T-Brain is the foundational AI that powers every Topsort product. It doesn't just optimize ads—it understands commerce at a molecular level, predicting what shoppers want before they know it themselves.
Three layers of intelligence
T-Brain isn't one model—it's an ensemble of specialized intelligences, each mastering a different dimension of commerce.
Relevance Engine
2.4 trillion signals processed dailyUnderstands shopper intent through behavioral signals, contextual analysis, and purchase graph modeling. Every ad shown is an ad that belongs.
Auction Intelligence
Self-improving with every transactionDynamically calibrates every auction in real-time—balancing advertiser ROI, publisher revenue, and user experience simultaneously.
Commerce Graph
500M+ product relationships mappedA proprietary knowledge graph mapping products, categories, brands, and shopper journeys across the entire commerce ecosystem.
AI that serves commerce—
not the other way around.
We believe artificial intelligence should be invisible, ethical, and relentlessly useful. T-Brain doesn't chase trends—it sets them. Every model is trained on real commerce outcomes, validated against fairness constraints, and deployed only when it makes things measurably better.
The brain behind everything we build
The future of commerce
is intelligent.
