## About this market
Agent systems for business operations are where the market's newest architecture meets its oldest requirement: the work has to be right. The agencies here carry verified B2B evidence alongside agent delivery. WeAreBrain's HEINEKEN Harry walks vendors through procurement onboarding. Modulai embedded a custom LLM agent in Optilogic's supply-chain design platform, giving natural-language access to the underlying models. AI Sisters ran an agent program inside ENGIE's global transformation, Algorithma's agents serve customer service and finance operations with two deployments quantified at adoption level, and Faculty, ML6 and Neurons Lab bring the register's most scrutinized delivery records to the category.

Interrogate agent claims harder than any other on this register, because the word is doing heavy marketing work in 2026. The differentiating questions: what tools can the agent call, what can it not do, and how is correctness checked before an action lands in a business system? Documented answers exist on this page—permission boundaries, review gates, evaluation runs. Where a candidate offers enthusiasm instead, the adjacent AI automation page holds firms solving the same problems with less architectural risk.

## Questions buyers ask

### How many AI agencies work with B2B on ai agents?
37 agencies in our directory combine verified B2B client evidence with documented AI Agents work. The current top-ranked are AI Sisters, Modulai, Merixstudio — 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 agents?
Published rates across this page's agencies run €20–130 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.
