What are the top-rated e-merchandising platforms for large retailers?

Hi All,

Opening a discussion around top-rated e-merchandising platforms for large retailers, especially tools that support multi-site catalogs, robust rules + AI ranking, and merch analytics at scale. Curious which solutions actually deliver a great experience for both merchants and engineers. (Pulled from G2’s Enterprise E-Merchandising page.)

• Algolia – Search + Merch Rules with Enterprise Scale: Powerful search, rules, and reporting built for speed and large catalogs. Does its dashboard give merch teams enough control without constant developer help?
• Netcore Unbxd – Product Discovery with AI Ranking: Unified search, PDP/PLP optimization, and recommendations geared to large catalogs. How well do its AI models balance revenue vs. relevance across regions?
• Bloomreach – Discovery + Merchandising for Complex Stores:Combines AI search/recs with business rules and rich analytics. For global programs, did it simplify governance (templates, guardrails) across brands?

Would love feedback from teams using any of these platforms:

• Which delivered the most consistent uplift across search, PLPs, and recommendations?
• How was the implementation and time to value (feeds, rules, governance)?
• Any unexpected advantages (e.g., test velocity) or pain points (e.g., data/seat fees) along the way?
