## About this market
Custom AI development for enterprises is where stack specificity and evaluation discipline separate delivery firms from workshop sellers, and this page holds the register's deepest enterprise bench, with nearly every firm carrying two or more documented enterprise clients. ML6's Scout24 build documents its evaluation framework: human testing plus LLM-as-a-judge against an 85% quality bar, which is the kind of detail that only exists when the work happened. Neurons Lab shipped Visa a twenty-language LLM content system in under two months with the stack published. Converteo's Orange voice agent and Modulai's Novo Nordisk retrieval system both describe production constraints rather than capabilities.

Development engagements are where handover matters most: which models, whose infrastructure, what the client's team can maintain alone. The firms at the top of this ranking publish those answers in their case studies; treat reluctance to name a comparable delivered system as information. Enterprise development quotes vary more by scoping quality than by rate—a precisely scoped build at a higher rate routinely lands cheaper than an open-ended one at a lower rate.

## Questions buyers ask

### How many AI agencies work with enterprise on ai development?
89 agencies in our directory combine verified enterprise client evidence with documented AI Development 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 development?
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 enterprise experience verified on this page?
Each listed agency has at least two documented, named enterprise 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?
4 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.
