How do you choose the right AI consultancy?

Decide whether you need advice, delivery, or both. A pure strategy engagement suits a classic consultancy; if the work must end in a live system, favour a firm like SD:UK that advises and builds. Then check their engineering credibility, cloud partnerships, and data-security posture, and ask for examples where their recommendations reached production.
