About this list
Most of the register's documented work is business-to-business, which makes this the broadest segment page—and the one where the definition earns its keep. An agency appears here when at least two of its documented, named clients were businesses buying for their own operations or their own business customers: HSBC's market-abuse surveillance models at Brainpool, HEINEKEN's procurement assistant at WeAreBrain, Deutsche Bahn anomaly detection at dida, Scout24's evaluation-framework build at ML6, generative support tooling inside Tide's live operation at Faculty. Classification follows the engagement, not the client's logo: a bank buying an internal document system is a B2B engagement even though the bank serves consumers.
B2B AI work has a shape worth knowing before shortlisting. The system usually lands inside an existing operational stack—an ERP, a CRM, a ticketing queue, a trading floor—so integration and permissions carry as much of the budget as the model does. Outcomes are measured in operational numbers: handle time, error rate, hours of preparation removed. And the buyer usually has to defend the purchase internally, which is why the agencies at the top of this list publish before-and-after figures rather than adjectives.
Twenty-seven agencies qualify, the largest roster of any segment. Use the documented-client counts on each card to separate practices with a body of B2B work from those with exactly two qualifying engagements, and use the city and service pages to narrow by geography or discipline.
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
A client whose engagement served business customers or internal business operations—classification follows the engagement context first, the client's primary revenue model as fallback. Two-sided businesses can legitimately count as both B2B and consumer, so some agencies hold both chips. Every listed agency evidences at least two documented, named B2B clients, with source URLs stored per client.
Each qualifying client comes from a published case study or engagement description our research read in full—never from a logo wall or a claimed client list. The evidence line on each card shows the agency's total documented clients across all segments, which is the honest number: we never invent per-segment counts the data does not have.
Because most AI delivery in Europe is B2B—the roster reflects the market, not a loose bar. The differentiation sits one level down: documented-client counts vary from two to more than a dozen, rates and cities differ, and the ranked order weighs portfolio quality and credibility.
