BLOGFractional AI
What is a fractional chief AI officer, and does an agency need one?
A fractional chief AI officer leads AI in your business for a few days a month. What the role covers, how it differs from a hire, and whether you need one.
A fractional chief AI officer is a senior person who leads AI in your business part-time. They work a few days a month, not five days a week, and they own the things a full-time head of AI would own: the direction, the tools, the rules, and whether the team can use any of it.
You’ll see the same role called a fractional head of AI, a fractional AI lead or a fractional AI consultant. For a business of twenty or fifty people they’re the same job. Here’s what it involves, and how to tell whether you need one.
What a chief AI officer does
In a large company, a chief AI officer sits on the leadership team and is accountable for how the business uses AI. Strip away the title and the job is five things:
- Direction. Where AI should change the business, and in what order.
- Tools. Which ones the business standardises on, and which it stops paying for.
- Rules. What can touch client data, what an agent can do alone, and what a person must always decide.
- People. Whether the team has the skills and the confidence to use it.
- Results. Whether any of it is saving time, improving the work or winning business.
Somebody in your business is doing this already, whether or not they have the title. In most agencies it’s the owner, at ten o’clock at night.
What “fractional” means in practice
Fractional means part-time and ongoing. You don’t hire them for a project and wave goodbye. They’re part of the team for a few days each month, and they own the direction in between.
Here’s the catch. The word is now used for two very different things.
- A bundle of hours. A monthly subscription that buys a few calls, some email support, or a strategist who also works for many other clients. Cheaper, and often fine for advice.
- A named senior person. Someone who has run a business, sits with your leads, makes decisions with you and is accountable for the outcome. Priced in days, not hours.
Both are sold as “fractional AI”, often at similar-looking prices. Plenty of websites don’t say how much time you get, or from whom. So ask:
- Who is the person, by name?
- How many days or hours a month do I get?
- What will they decide, and what will they build?
“Fractional” covers a bundle of hours and a named senior person. Ask which one you’re buying.
Fractional lead, full-time hire, project or champion
| What it is | Fits when | |
|---|---|---|
| Full-time head of AI | A senior employee, five days a week | AI is central to the product, and there’s a team to lead |
| Fractional AI lead | A senior person, a few days a month, ongoing | AI needs an owner, but not a full-time one |
| Consultancy project | A fixed piece of work with an end date | You need one thing assessed or built |
| Internal AI champion | A team member who makes it stick day to day | Always, alongside any of the above |
They aren’t alternatives so much as layers. The pattern I see work in agencies is a part-time lead from outside, paired with a champion on the inside.
Does an agency need one?
Most of what’s written about this role compares it with hiring a full-time chief AI officer, at a salary of £120,000 or more. That comparison doesn’t mean much to an agency owner. If you run 20 to 80 people, you were never going to make that hire.
The real question is simpler. Who owns AI in your agency today?
If the answer is “me, when I get time” or “everyone, sort of”, that’s the gap. And it’s getting more expensive to leave open, because your clients are moving. The State of PPC Report 2026 found that 20% of clients plan to replace some agency work with AI, nearly double the 12% who plan to switch agencies. In Luma’s 2026 research, 53% of brand-side respondents expect to reduce agency spending because their own AI tools will let them do more in-house.
Agencies don’t measure this against a salary. They measure it in margin, utilisation and whether clients stay.
Signs you probably do
- AI is being used all over the agency, and nobody can say what you get from it.
- The owner is the only person thinking about it, and has no time to.
- Clients are asking how you use AI, and you don’t have a confident answer.
- You’ve tried things, and none of them became how the agency works.
- Your team is divided between the keen and the worried.
Signs you don’t, yet
- You’re fewer than about ten people. Start with one tool and one champion.
- Someone senior already owns it and has the time.
- You only need one specific thing built. That’s a project, not a role.
What to ask before you hire one
- How many days do I get, and with whom? If they can’t say, it’s an hours bundle.
- Have you run a business like mine? Advice from someone who has never had to make payroll in an agency lands differently.
- Do you build, or only advise? Direction without building rarely changes anything.
- How does it end? A good fractional lead plans to need fewer days over time, and says so at the start.
- Who owns what we build? The agents, the standards, the documentation. It should all be yours.
- Can I leave after the first few months? A long lock-in protects them, not you.
How I do it
I work as a fractional AI lead for agencies, because I’ve run one for 20 years and rebuilt four of my own around AI. It starts with a fixed Blueprint that takes about two weeks, so we both know where the value is. Then there are three levels:
- Advisor: two strategy calls a month, for owners whose own team does the work.
- Lead: a weekly check-in and two working days a month inside your team.
- Embedded: about one day a week, building alongside your people on live work.
Plans run for three months to start, then month to month. As your team takes more on, we step the plan down, and when you’re ready, I step back. You own everything we build.
The prices are published, and I’ve compared them with the rest of the market in how much an AI consultant costs. If you’d like to talk it through, send me a message.
