Guide

How to choose

Choosing the right AI consultancy depends on your organisation's size, maturity, budget, and specific goals. Large enterprises with complex, multi-year transformation programmes may benefit from the scale and methodology of big consultancies like Deloitte, Accenture, or McKinsey's QuantumBlack. These firms offer proven frameworks, large teams, and global reach — but at premium pricing that can exceed six figures per engagement. For mid-market businesses or those seeking practical, hands-on AI implementation, boutique specialists like Grove AI offer a more cost-effective approach. Boutique firms typically provide senior practitioners who work directly with your team, deliver faster time-to-value, and focus on pragmatic solutions rather than lengthy strategy documents. They are particularly effective for organisations taking their first steps with AI or needing targeted solutions for specific business problems. Consider the consultancy's domain expertise and technical depth. Some firms specialise in specific technologies (NLP, computer vision, optimisation) or industries (financial services, healthcare, public sector). Ask for relevant case studies and references. Evaluate whether the consultancy will build your internal capabilities or create dependency — the best partners invest in training your team alongside delivering solutions.

FAQ

Frequently asked questions

Costs vary widely. Discovery workshops and assessments start from £5,000-£15,000. Proof of concept projects range from £25,000-£75,000. Full implementation programmes can cost £100,000-£500,000+. Big consultancy firms charge £1,500-£3,000+ per day; boutique firms typically £800-£1,500 per day.

No — in fact, developing an AI strategy is one of the most common reasons to engage a consultancy. Many firms offer discovery or strategy sprints (1-4 weeks) to help you identify where AI can deliver the most value before committing to implementation.

Big consultancies offer scale, methodology, and brand trust but at premium cost with junior staff doing much of the work. Boutique firms offer senior expertise, faster delivery, and better value for focused engagements. Many organisations use boutiques for initial AI work and scale up if needed.

Relevant case studies and domain expertise, transparent pricing, a focus on knowledge transfer (not dependency), technical depth alongside business understanding, and a clear methodology for measuring ROI. Ask who will actually do the work — demand senior practitioners, not just sales teams.

Discovery and strategy: 2-6 weeks. Proof of concept: 4-12 weeks. Full implementation: 3-12 months. Ongoing partnership and optimisation can be continuous. The best engagements start small, prove value, and expand based on demonstrated results.
