About this list
Frankfurt's B2B buyers meet two different kinds of supplier on this page, and the published work tells them apart quickly.
Adastra is the one with AI in production: an agentic control layer at the Slovenian bank NLB with identity-based approvals and cost monitoring on Grafana, enterprise search for KWS on Amazon Bedrock delivered inside a Teams channel, and a print-bundling optimizer for GZ Media taken past proof of concept into a production application.
The others document delivery of a different kind. Shift Agency rebuilds brand and commerce platforms—entega.de migrated in six months with ten order flows reworked—and lists AI services that no case study yet stands behind. Qubix Consulting publishes ordering, ERP and shop systems for wholesalers and manufacturers, with AI staffed on the team page rather than shown in the work. Qemie sells the plumbing: scrapers and enrichment feeding a CRM, a ranking engine choosing the outreach channel per region, a migration that returned fifteen hours a week.
That gap decides the brief. A system that has to survive an audit, an identity boundary and a cost ceiling is one purchase; wiring between a website, a CRM and a mailbox is another, and usually the cheaper problem. Ask any candidate here what their last three engagements actually were, and who operated the result once the invoice was paid.

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.
