About this list
Commerce is the segment where AI meets numbers a startup already watches daily—conversion, return rate, basket size—so read the documented work against those. Modulai's personalization serves millions of Lindex retail customers, alongside demand and behavior models across several consumer businesses. 010 Coding Collective's in-store returns tool is live at INTERSPORT and Runnersworld, recognizing shoe brands on return and feeding the data back to the retailer. Dashbouquet's extraction work is the infrastructure underneath commerce intelligence: menus from 10,000-plus venues in 12 languages at 100 GB a day, and a second system tracking 21,000 SKUs across nine marketplaces. AI Pirates' Fuxtec engagement is a prioritized 18-month roadmap rather than a build, and xtream's commerce-adjacent work is planning and forecasting with the solver named.
Two cautions specific to this category. Commerce AI is sold on percentage uplifts more than any other, so ask what the number was measured against and over what period—an uplift with no control group is a story. And ask what the system did in the candidate's highest-volume week, because a recommender that degrades on peak trading days fails exactly when it was supposed to pay for itself.

Expert Insight
Why E-commerce experience matters
Measurement discipline—E-commerce AI can and should be A/B tested against revenue. Specialists propose baselines, holdouts, and target metrics before writing code; be suspicious of anyone who wants credit for a lift they didn't isolate from seasonality and campaigns
Platform constraint fluency—A recommendation engine that can't be served within Shopify, commercetools, or your legacy stack's latency and API limits is a research project. Specialists design for the platform you run, not the one their demo runs on
Catalog-data pragmatism—Attribute gaps, inconsistent taxonomies, and thin product descriptions are the default, and they cap what personalization and search can do. Specialists budget the data-cleanup phase honestly and often automate it with generative models as part of the build
Seasonality and drift—Recommendation and forecasting models decay as catalogs, seasons, and campaigns change. Specialists set up monitoring and a retraining cadence at launch, because a model tuned on winter traffic quietly loses money by summer
