Built for modern commerce.
Every business monetizes differently. Topsort adapts to your marketplace, shopper journey and economics.
Every solution runs on the same core platform.
Sponsored listings, display, brands, video, offsite and in-store aren't separate products. One auction, one relevance engine, one budget system and one measurement layer power all of them. A new format or market is a configuration change, not a rebuild.
