Alternatives to big AI consulting firms (and when they're the wrong shape)

Most companies looking for AI help start with the names they recognise: McKinsey, BCG, Bain, Accenture, Deloitte, EY, KPMG, PwC. Sometimes that's right. Often it's not. Here's the honest take from the boutique side of the table.

When the big firms are the right call

Before we make the case against, let's make the case for. A Big Four / MBB engagement makes sense when:

• You're a Fortune 500 with board-level pressure to "have an AI strategy" and you need the political cover that a recognisable logo provides.

• The deliverable is genuinely a strategy artefact - a multi-year transformation roadmap, a target operating model, a governance framework - and not a working system.

• You need 30 people on the ground in 6 countries next quarter. Boutiques can't staff at that scale.

• You have regulatory or audit requirements that effectively mandate a Big Four name on the contract.

If that's you, hire them. Use the rest of this article to negotiate.

Where it gets expensive and slow

The same engagement shape that works for "transform the enterprise" tends to fail in three predictable ways when you're trying to ship working AI in months, not years:

1. The senior people you bought aren't the ones doing the work. A partner sells, a senior manager scopes, and the actual delivery sits with consultants two years out of an MBA who've never shipped a model to production.

2. The deliverable is a deck, not a system. You pay six or seven figures for a roadmap that, on month one of execution, you realise you can't actually implement without hiring engineers.

3. The pace is wrong. A 16-week discovery phase is fine when the problem is "redesign our global operating model." It's absurd when the problem is "automate our invoice intake."

If any of that sounds familiar, you're probably in the wrong engagement shape.

What a boutique AI consultancy actually does differently

The honest version, not the marketing version:

• Senior people do the work. The person you talked to in the sales call is the person writing the prompts, designing the eval set, and pushing the code. There is no army of juniors behind a curtain.

• The deliverable is a working system, not a deck. A deployed workflow, a measurable improvement, a system someone on your team can run after we leave. The strategy emerges from the build, not before it.

• Engagements are weeks, not quarters. A first useful thing in 2–6 weeks, not month 4 of a 12-month transformation.

• Pricing is project- or outcome-based, not "1,800 consultant-days at €X/day."

• You can replace us. Everything we build is yours, in your accounts, with documentation a competent engineer can pick up. No vendor lock-in, no rented platform.

When a boutique is the wrong call

Be honest with yourself. A boutique is the wrong fit when:

• You need 50 bodies on the ground.

• The political reality of your organisation requires a name your board recognises.

• You don't know what you want and you need someone to spend six months figuring it out at scale.

• You want someone to take the blame if it fails. Big firms are very good at being the named scapegoat.

How to choose

A few questions that cut through the pitch:

1. "Who specifically will do the work, and can I meet them before I sign?" If you can't, you're hiring a brand, not a team.

2. "What's the smallest useful thing you can ship in 4 weeks?" If the answer involves another discovery phase, run.

3. "What does success look like, measured?" Vague answers ("transformation," "alignment") mean unmeasurable invoices.

4. "What happens to this when you leave?" Anything that requires the consultancy to keep operating it is a lock-in trap.

5. "Show me three things you've shipped to production in the last 12 months." Strategy decks don't count.

6. "How will you help us prove compliance with the EU AI Act?" The AI Compliance Evidence File EU regulators actually want is non-trivial, and the €35M penalty math means vague answers here are a red flag.

If a firm can't give you a clear answer to all six, the size of the logo doesn't matter.

What this looks like in practice

We've shipped automation workflows in 3 weeks for clients who were quoted 9-month engagements by Big Four firms - same problem, same scope. Not because we're geniuses. Because the engagement model is built for shipping, not for staffing.

That trade-off doesn't always favour the boutique. But it favours us often enough that "alternatives to big AI consulting firms" is a question worth asking before you sign anything.
