Our verdict on SLI Systems

SLI Systems is a cloud-based ecommerce product-discovery suite for retailers that want shopper behavior to shape search and navigation. Its machine-learning search predicts products shoppers are likely to buy, while learning navigation dynamically builds pathways from shopper behavior. The suite also includes personalized recommendations, autocomplete, merchandising controls, SEO tools and analytics. Retailers across small, mid-market and enterprise sizes are listed as a fit, with web and mobile experiences in scope.

The product combines automated discovery with retailer control over product presentation. Merchandising can be manual or automated for search and category results, and segmentation can account for geography, shopper attributes and device. Personalized recommendations support cross-sell and upsell placements, while analytics dashboards and customizable reporting provide ways to review performance. SEO landing pages and organic-search tools extend the suite beyond on-site search. This breadth is relevant to retailers seeking to manage discovery across several parts of the shopping journey rather than add a standalone search box.

Integration is described through an HTTP API supporting XML, JSON and JSONP, including for search, navigation and recommendations on websites or native mobile applications. That makes API-led integration central to the product's fit; retailers should assess the implementation work against their own architecture. Pricing follows a contact-sales model, and prospects are directed to book a demo rather than choose a self-serve plan. Email is the listed support channel. SLI Systems suits retailers looking for behavior-led discovery and merchandising across web and mobile, while teams that need published self-serve pricing or prefer a product with a different integration approach may want to compare alternatives.
