## Buyer questions

### What does an AI consulting firm do?
An AI consulting firm scopes, builds, and deploys machine-learning and LLM systems for client companies: use-case selection, data readiness, model development, integration, and the governance around them. Engagements range from strategy advisory to full delivery teams. It differs from a software agency by owning model performance, not just shipping features.

### What are the top AI consulting firms?
The market tiers into global consultancies (Accenture, McKinsey QuantumBlack, BCG X, Deloitte, and IBM Consulting) for enterprise-scale programs, and specialist AI boutiques for scoped delivery. Which tier fits depends on budget and scope: enterprise engagements typically start around €26K, while European specialists typically charge €65–110/hr and €2.2K–6.9K/mo on retainer.

### What are the top AI consulting firms in Europe?
AIAgencies.eu ranks 31 reviewed European AI consultancies by published evidence: portfolio quality, credibility signals, and profile completeness. The current top-ranked firms are Artefact, ML6, Faculty, listed in the register tiers on this page with the evidence behind each ranking.

### How much do AI consulting firms charge?
Boutique AI consultancies typically charge €2.2K–6.9K per month on retainer, with European hourly rates of €65–110/hr. Enterprise engagements at global consultancies typically start around €26K and scale with workstreams. Most projects run 3-6 months from scoping to first production deployment. The hourly band comes from our rate index; retainer and engagement-floor figures are editorial estimates from published rate cards and pricing pages.

### Should I hire a global consultancy or an AI boutique?
Choose a global consultancy when the program spans many systems and business units, needs formal governance, or must clear enterprise procurement. Choose a boutique when the scope is a defined build, the budget sits under roughly €100K, and speed matters: senior people do the work directly rather than a large mixed-seniority team.
