Short answer: most AI strategy work fails at the handover — a slide deck arrives, nobody builds anything. The firms below fall into two camps: advisory-only consultancies and consultancies that also deliver the build. If you want measurable results inside a year, choose a partner who will ship the first system, not just recommend it. Pearl Lemon AI does both, with projects starting from £5,000.
How we compared these firms
- Advice or delivery — does the engagement end at a roadmap, or with a working system in production?
- Use-case selection — is prioritisation tied to measurable cost or revenue, or to technology trends?
- Data readiness — do they audit the data before promising outcomes?
- Governance and risk — how are accuracy, privacy and human oversight handled?
- Cost and commitment — first-phase price and what it buys.

Working on this yourself? Our Ai Strategy Consulting team scopes and builds these systems end to end — proof of concept in 2–4 weeks, production builds from £15,000.
1. Pearl Lemon AI
We run strategy as a short, evidence-led phase, then build. A typical engagement: interview the teams doing the work, map the workflows and their real cost in hours, check whether the data behind each candidate use case exists and is usable, then prioritise on payback rather than novelty. You get a ranked use-case list with effort and expected outcome per item — and, crucially, we can build the top item straight away.
Delivery covers proof of concept, production build, integration into the tools your team already uses, and reporting on hours saved, accuracy and cost per outcome. Projects start from £5,000, quoted after a 30-minute scoping call.
2. Muteki Group
Consulting and engineering across data and AI programmes. Reasonable where strategy needs to sit alongside broader technology change.
3. Tezeract.ai
AI product and consulting firm with computer vision and NLP delivery experience. Ask which of their case work matches your industry.
4. 9series
Software services company offering AI advisory alongside development capacity. Suited to teams that want one supplier for both.
5. FXIS.ai
Applied AI consultancy focused on model development and deployment. Best where the problem is clearly a machine-learning problem already.
6. Deviniti
Enterprise software and process consultancy with AI and automation practices, often anchored around Atlassian and enterprise tooling.
7. InData Labs
Data science and AI consultancy with a strong analytics and predictive-modelling focus. Good fit for forecasting and data-heavy use cases.
8. DataRoot Labs
R&D-oriented AI partner for startups and scale-ups. Consider them where the work is genuinely novel rather than an integration problem.
9. deepsense.ai
Research-led machine learning consultancy with enterprise clients. Expect a scientific approach and a corresponding budget.
10. DataForest.ai
Data engineering and AI delivery, useful where pipelines and data infrastructure must be built before any model is worth training.
What to ask before you sign
- Will this engagement end in a document or a working system?
- How do you prioritise use cases — what is the payback calculation?
- What happens if the data is not ready?
- Who owns the models, code and prompts afterwards?
- What does phase one cost, and what does it deliver?
Want a roadmap you can actually build from?
We will map your workflows, score the use cases on payback, and quote the first build. Projects start from £5,000. See AI strategy consulting and AI consulting services.
