## About this market
Generative AI for business operations is a narrower discipline than the hype suggests: the output lands in a workflow with an owner, so accuracy, evaluation and escalation are the specification. Every agency here carries verified B2B evidence with generative delivery behind it. Faculty's AgentAssist and MemberSummarise run inside Tide's support operation on Amazon Bedrock, with a published 10% handle-time cut. Neurons Lab shipped Visa a twenty-language LLM content system in under two months. Lautmaler integrates LLMs into conversational systems with quality measurement described in the case, and DataNorth's programs pair generative tooling with the enablement that makes internal teams productive with it.

The B2B lens sharpens the buying questions. Where does generated output enter the workflow, and what checks it before it acts or ships? Which failure modes were designed for—hallucinated facts, stale knowledge, tone drift—and what does the human-review loop cost at volume? Teams that have operated generative systems answer from artifacts: evaluation suites, guardrail configs, escalation paths. This page lists the agencies whose published work shows those artifacts exist.

## Questions buyers ask

### How many AI agencies work with B2B on generative ai?
52 agencies in our directory combine verified B2B client evidence with documented Generative AI work. The current top-ranked are Square Root Solutions, Storm Technology, Modulai — 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 generative ai?
Published rates across this page's agencies run €20–175 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?
2 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.
