Key takeaways
• Pick by your problem, not brand size.

How to choose your AI consulting partner
The best firm is rarely the biggest or cheapest. It is the one with real results in your industry.
- Name the problem: strategy, compliance, legacy or speed.
- Meet the real team: ask who staffs your project day to day.
- Ask about a failure: it shows how they handle setbacks.
- Start small: agree one measurable milestone before a long contract.
- Plan for adoption: training and change management, not just the build.
Where design fits in an AI rollout
An AI tool only pays off if people use it, and clear screens often decide that. Read why the best work needs both AI and humans, what AI cannot do in design and why your product UI sells.
Frequently asked questions
What do AI consulting companies do?
They find where AI will pay off, prepare data, build or buy models and roll them out safely.
Big firm or smaller firm?
Big firms suit multi-country, high-risk programmes. Build-focused firms often move faster and cost less.
Can we build AI in-house instead?
Many do both: a partner for the first build while an internal team learns to take over.
