About this list
Commerce B2B work—systems for retailers and the businesses serving them—is where AI meets numbers the client already watches daily, and the nine agencies here document work against those numbers. Modulai's recommendations serve Lindex's millions of customers. WeAreBrain's HEINEKEN receipt validation processed 30,000-plus receipts across three campaigns at around 80% automatic recognition. Amsterdam Data Collective attacks markdown optimization directly, Artefact and Rewire bring retail programs with published figures, AI Pirates ran the AI roadmap for Fuxtec's e-commerce operation, and Brainpool, Algorithma and Ortom complete the roster.
The baseline question does the sorting here: commerce AI is sold on uplift percentages, so ask what every number was measured against, over what period, and what happened in peak trading. Then ask about the data layer—recommendation and pricing systems are only as good as the product and transaction data underneath, and several agencies on this page build that layer as part of the engagement. The ones that do tend to be the ones whose case studies survive the baseline question.
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

Published rates across this page's agencies run €85–175 per hour (median ~€130). Project totals depend on scope — our cost calculator breaks estimates down by team size and engagement length.
Each listed agency has at least two documented, named B2B clients — published case studies or engagement descriptions our research actually read, with source URLs stored per client. Logo walls without published evidence carry no weight, which is what separates this list from self-declared directories.
