About this list
The e-commerce work documented on this page is unusually well measured, and worth reading closely. Wolfgang Digital's controlled test for Very Ireland had Producthero's AI rewrite 1,471 Shopping product titles against an identical campaign, reporting CTR 11% higher and ROAS 5% higher by month four; at Petstop, Klaviyo's Expected Date of Next Order model drives a reorder flow credited with 36% incremental revenue over six months. Algorithma's agents handle Byggmax's email, chat and phone inquiries, reported at more than 80% fewer human-managed tickets, and resolve about 35% of CDON's inquiries. NOVOS reports Osprey's share of AI answers up 21.4 points to 72.6% and MORI's December revenue up 73% year on year after the acquired KIDLY site moved onto Shopify. Contiamo's Product Text Wizard generates multilingual product descriptions for BRAX from its ERP and PIM, with no case-study page behind it. Alpdev's AI Convert It engages visitors about to leave without buying, and its Bent Asistent recommends products by linking to real ERP catalog entries. Square Root's Jump Juice Bars app carries recommendations and an unexplained 40% engagement figure, and b.telligent's OTTO engagement is a platform migration without an AI component.
The sorting question for a mid-market retailer is who owns the model when the agency changes. The Very Ireland and Petstop results run on Producthero, Klaviyo and OpenAI features the client licenses; the Byggmax, Bent and BRAX systems were built for the client. Ask for the control group behind any percentage, and for the tooling bill after handover.

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
