## About this market
'AI consulting' on this page often means the layer under the model. KVL's documented engagements are data platforms and the teams to run them: a central warehouse and data organization for a.s.r. Schade with staff trained through its academy, Middin's warehouse migrated to TimeXtender in eight months with KVL people added to the in-house team, and junior data professionals recruited and trained for PGGM since 2018. Marionete's AXA engagement is an MLOps factory on Databricks with a model registry, champion-challenger releases and human approval gates, adopted by four teams across two business units. Transparity's consulting is Copilot adoption, RNIB from 30 to 300 licenses and Alzheimer's Society to 1,800 colleagues, plus governance planning. Stepwise placed six to ten staff on Ackwest Group's data platform for two years, though the client's Clutch review rated cost 3.0. Satalia's advisory pedigree is operations research, with the Tesco and PwC systems still running a decade on. Some of the consulting does reach the model: DEUS's voice AI handles ABN AMRO's customer service calls autonomously, including caller identification, and Neurons Lab delivered an LLM content system for Visa across 20 languages alongside enablement work such as a one-day program for HSBC Vietnam's banking leaders. Where the AI is thin, the curator notes say so: KVL's visible team has no data scientist or ML engineer, Syncronika's client cases are web and marketing work, and Marionete has no generative system in production.

For a buyer extending a team with consultants, the sorting question is what your own people can do when the consultants leave. KVL and Transparity document training as part of the engagement; Marionete documents a platform other teams adopted. Ask each candidate which of those they are selling, and for a client whose in-house team now runs the result without them.

## Questions buyers ask

### How many AI agencies work with team extension on ai consulting?
28 agencies in our directory combine verified team extension client evidence with documented AI Consulting work. The current top-ranked are Old St Labs, Lexunit, Pixelette Technologies — 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 €20–130 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 the team extension model verified?
Every agency here documents team extension 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 team extension engagements deliberately.
