Poor retail search buries relevant stock and costs conversions; Constructor uses shopper behavior to improve product discovery. It is especially good at ranking large catalogs around purchases rather than simple keyword matches.
Nosto personalizes ecommerce storefronts, giving merchandising teams practical control over recommendations, search, category ordering, and segmented content.
When shoppers cannot put a product into words, Syte uses visual AI to connect images and intent with relevant items across a retailer’s catalog.
Shoppers often know what an item looks like but not the words to search for. ViSenze gives retailers visual search, catalog tagging, and recommendation APIs suited to image-heavy product catalogs.
