## About this market
Generative-AI projects here are mostly retrieval and drafting systems with a person in the loop, and the generative record on several of these sites is shorter than the classical one. Merantix Momentum's rolled-out generative systems are Cornelsen's Material Designer, launched 2024 and in daily use by teachers, and Hamburg's LLMoin assistant; its Federal Chancellery work ended as a proof of concept handed over for integration. Datatonic's AstraZeneca RAG pipeline ingested 20,000-plus documents and its Alpian banking agent runs customer-facing under FINMA supervision, each quantified as engineering rather than outcome. Kortical's chatbot for The Edit LDN reports 80% of queries handled automatically and an 88% cut in support costs. Babel's WiZink platform reviews every customer interaction in Spain and Portugal, cutting a campaign review from days to hours. Instituto de Ingeniería del Conocimiento's strongest generative figures name no client, and Mercury Labs' IfATE tools keep judgment with the reviewer but publish no metric.

The sorting question for a generative-AI project is how the output was evaluated before go-live and who checks it after. Merantix Momentum's caralegal contract reviewer is quoted at 60-plus percent agreement with experienced lawyers, the figure to ask for, along with the evaluation set and review queue. Ask what the project left behind for re-evaluation when the model or documents change; where the work is a proof of concept, ask who integrated it and whether it is in use. Prefer figures with a named client attached and treat an anonymous percentage as a claim to verify.

### How much does an AI agency cost for generative ai?

### How is the project-based model verified?
Every agency here documents project-based work on its own site or in a published case study, describing the engagement structure rather than a service-list claim. We never infer the model from portfolio tone, so this list only contains agencies that operate project-based engagements deliberately.

### Can these agencies embed consultants with our team?
9 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.
