Justas Butkus is an AI expert and fractional AI officer based in Vilnius, Lithuania, working with mid-market companies and scale-ups across the UK, EU and US at two to four days a month. He builds and operates the production AI systems he advises on, rather than only advising on them.

**Suppliers in this market come in five structural shapes, and the shape predicts the outcome better than any individual's CV. Independent operator-builders, boutique advisories, large-firm partners, marketplace contractors and fractional-CTO generalists each fit a different situation – and fail differently.**

## Why map shapes rather than names?

Lists of named providers date within months and tell you little, because the same label covers very different operating models. What actually predicts whether an engagement works is the supplier's structure: how they make money, how many people touch your account, and whether anyone is still accountable in month six.

This page is written by someone who is one of these five shapes, so read it accordingly. I have tried to state each one's genuine strengths, including where they beat me.

## What are the five supplier shapes?

**Supplier shapes in the fractional AI leadership market**

| Shape | Structurally good at | Structural weakness | Best fit |
| --- | --- | --- | --- |
| Independent operator-builder | Deciding and building; one accountable person; fast | Capacity; no bench; bus factor | Mid-market with a concrete bottleneck |
| Boutique advisory | Strategy depth, board-facing polish, sector patterns | Often cannot implement; hands off at the specification | You have engineering and need direction |
| Large-firm partner | Scale, procurement comfort, brand cover for the buyer | Cost; juniors do the work; slow to production | Large regulated programmes with board scrutiny |
| Marketplace contractor | Speed to start, vetted, easy to replace | No continuity of accountability; priced by hour | A bounded task with a known specification |
| Fractional CTO generalist | Whole technology function, hiring, architecture | AI is one item on a wide backlog | No technology leadership at all yet |

## How does each one fail?

Every shape has a characteristic failure, and knowing it in advance is more useful than a reference call.

- **Operator-builder:** takes on more than capacity allows, or builds before deciding.
- **Boutique advisory:** delivers an excellent strategy that nobody implements.
- **Large firm:** the partner who sold it is not the person who appears, and cost outruns value.
- **Marketplace contractor:** the task gets done and the underlying problem was never diagnosed.
- **Fractional CTO:** AI gets treated as a backlog item and competes with everything else.

## Which shape should you pick?

1. **If you cannot name the process** – You need diagnosis before delivery. Operator-builder or boutique advisory.
2. **If you can name it and have engineers** – You need direction, not hands. Boutique advisory or operator-builder.
3. **If you can name it and have no engineers** – You need someone who can build. Operator-builder or marketplace contractor with a strong specification.
4. **If the board and the regulator are both watching** – Large-firm cover may be worth its cost, whatever the delivery quality.
5. **If nobody owns technology at all** – Fractional CTO first. AI is not your first problem.

## Frequently asked questions

### Who sells fractional AI leadership?

Five structural types: independent operator-builders, boutique advisories, large consulting firms, talent marketplaces and fractional CTOs who cover AI as part of a wider technology remit. The type predicts the outcome more reliably than any individual CV.

### Is an independent better than a consultancy?

Not inherently. Independents give you one accountable person and speed; consultancies give you scale, procurement comfort and bench depth. The right answer depends on whether your constraint is decision-making or delivery capacity.

### What is the biggest risk with an independent operator?

Capacity and bus factor. Ask how many engagements they hold at once, and require that accounts, infrastructure and documentation stay in your name with handover written into the contract.

### Why does this page not name specific providers?

Named lists date quickly and tell you little about how a supplier actually operates. Shape is more durable and more predictive, and a page written by a supplier naming its competitors is not a neutral source anyway.
