About this list
Vienna's B2B page runs from production systems to research rigs, and the published evidence thins in that order. craftworks' success stories describe visual-inspection systems running on production lines with measured outcomes, on its own navio MLOps platform with retraining, blue/green deployment and edge rollout. allUpp works inside Salesforce: two of its client stories involve AI, both Agentforce setups—SSI Schäfer's service-email triage, which routes clear cases and hands uncertain ones to a person, and a case-summary agent for vibe moves you—while the rest document CRM rollouts. DatenVorsprung's work is verification: a reinforcement-learning controller on a Beckhoff rig checked at 95% confidence and an autonomous-driving model tested until it lost control, published as research rather than client deployments. Waterglass names InStaff, notus, HHLA Next and Heylog as clients, with a line each rather than a case study.
The sorting question for a B2B buyer is whether you need a system running on your own lines, an agent inside a platform you already license, or evidence that a controller is safe before certification—the firms here answer different ones of those. Ask for the production reference closest to yours, and where the model runs.

Expert Insight
Why B2B fit matters
B2B AI lives inside operational systems, so integration experience is delivery experience—an agency that has shipped into an ERP or a ticketing queue has already fought the battles your project will fight.
Operational outcomes are checkable in a way marketing outcomes are not: handle time, error rate and hours removed either moved or they did not, and the strongest agencies here publish those numbers.
The internal business case matters—an agency whose case studies quantify results gives your sponsor the numbers to defend the budget with.
Frequently asked questions

Published rates across this page's agencies run €45–85 per hour (median ~€65). Project totals depend on scope — the rate index at /rates breaks the computed bands down by region, country and team size.
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.
