## About this market
This is one of the largest pages in the segment register—every firm on it carries verified B2B client evidence and offers AI consulting—because most European AI consulting is B2B consulting. The range is the point. At the institutional end, Artefact, Faculty and ML6 sit among the register's highest-scoring firms, each with documented engagements that describe deployment and adoption rather than capability. In the middle, specialists like dida, Brainpool and Modulai consult from an engineering base—advice grounded in systems they then build. At the focused end, firms like appleute and Sputnik Digital advise the scoped-build buyer.

With a roster this size, use the two numbers on every card: the documented-client count, which separates a body of B2B work from exactly two qualifying engagements, and the rate band where published. Then apply the one question that sorts consulting fastest—where does the engagement end? A roadmap, a pilot and an operated system are three different purchases at three different prices, and every agency here sells at least one of them well. The expensive mistake is buying one while needing another.

## Questions buyers ask

### How many AI agencies work with B2B on ai consulting?
104 agencies in our directory combine verified B2B client evidence with documented AI Consulting work. The current top-ranked are Storm Technology, AI Sisters, Lexunit — ordered by depth of documented client evidence, then our editorial scoring (portfolio quality, credibility, completeness); placement is never paid.

### How much does an AI agency cost for ai consulting?
Published rates across this page's agencies run €20–260 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.

### How is B2B experience verified on this page?
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.

### Can these agencies embed consultants with our team?
3 of the agencies on this page document an embedded / team-extension working model. See the team-extension page for the full verified list, or check the engagement chips on individual profiles.
