Part of our guide: Fractional Chief AI Officer
You know what needs to happen, and you have been reading about AI for two years, probably running a few proofs of concept along the way. You may have given your teams access to Copilot or ChatGPT and seen varying degrees of adoption, with some teams enthusiastic and others sceptical. And the CEO keeps asking what our AI strategy is, as if the answer is a simple one.
You do not have the bandwidth to lead an AI programme on top of everything else you are already responsible for. You're running infrastructure, managing security, keeping the lights on, dealing with regulatory tech obligations and trying to modernise a legacy estate that was underinvested for years before you arrived.
What you need instead is someone senior who can own the AI strategy, working alongside you rather than requiring hand-holding.
What a Fractional Chief AI Officer actually does
A fractional CAIO (or fractional CTO with AI expertise) works as part of your leadership team on a part-time basis, typically 1-3 days per week. They bring the strategic depth and delivery experience of a full-time CAIO without the cost, the recruitment lead time or the risk of a bad hire.
In practice, this means:
They build and maintain the AI roadmap, owning strategy end to end and ensuring it is aligned to business priorities and not just a wish list of technology experiments. They also translate between the language of the business (cost, growth, risk) and the language of technology (models, data, integration).
Governance and risk oversight. In regulated businesses this is critical, and they design the governance framework, ensure AI initiatives meet regulatory expectations and give the board clear, candid reporting on AI risk and progress.
Vendor and partner management. The AI vendor market is noisy and fast-moving, and a fractional CAIO evaluates vendors, manages proof-of-concept engagements and prevents the business from making expensive technology bets based on impressive demos rather than real fit.
Team capability building. They mentor your existing technology team, helping them build AI skills and confidence, and the goal is capability transfer, not dependency. Your own team should be more capable because of the fractional CAIO and should not end up reliant on them.
Board and stakeholder communication. They translate AI progress and risk into language that non-technical board members can understand and act on, covering quarterly board updates, investment cases and progress reporting. That is the kind of senior communication that requires credibility and experience.
What it costs
The economics are straightforward. A full-time Chief AI Officer is a commitment of well over £250,000 in the first year once you add employer National Insurance, pension, benefits and recruitment fees to a six-figure salary, and that is before the risk of a mis-hire. A fractional model gives you senior AI leadership at the cadence you actually need, without the recruitment cost or the commitment of a permanent appointment, and with the flexibility to scale up or down as the programme matures. The exact investment depends on the level of support your business needs, which is why we scope every Grow engagement individually and give you a straight number in the first conversation.
Whether you need one
You probably need a fractional CAIO if:
Your CEO or board is asking for an AI strategy and you do not have time to build one properly alongside your existing responsibilities. The AI conversation has stalled between "we should do something" and "here's specifically what we're going to do." Or you have run some POCs and nothing has moved into production, and the gap between experimentation and deployment is where most AI programmes die. A fractional CAIO bridges that gap with governance, operating model design and delivery oversight, moving work from experiment into production. Or your business sits in a regulated sector where AI governance is becoming a board-level concern, and a fractional CAIO with regulated-sector experience can design the governance framework and provide the accountability the board needs.
You are a PE-backed business where AI is part of the Value Creation Plan and nobody is specifically accountable for delivering it. The fractional model lets you demonstrate progress to investors without the overhead of a full-time hire.
What to look for
Not all fractional CTOs or CAIOs are equal, and here is what separates the useful ones from the ones who will produce a slide deck and disappear:
AI strategy is a business design exercise rather than a technology exercise, and operating model experience matters more than technology knowledge alone. The person you hire should therefore understand operating models, capability mapping, governance and change management, not just machine learning architectures.
Regulated-sector track record. If you are in insurance, financial services, legal or professional services, generic AI expertise on its own is not enough. You need someone in the seat who understands SMF accountability, Consumer Duty, operational resilience and the specific regulatory expectations of your sector.
Delivery experience, not just strategy. The question is whether they can build something rather than only advise, and the best fractional CAIOs can take an initiative from strategy through pilot delivery to operational embedding. If they hand you a roadmap and leave, you are paying for slides.
Cultural fit with your leadership team. A fractional CAIO sits in your senior team and needs to build trust with your CEO, your CFO, your CRO and your board. Building that trust requires more than technical skill, and it requires judgment, communication and the ability to navigate organisational politics.
How we do it
At Oxygen Bubbles, our Grow service provides fractional Chief AI Officer support on exactly this model, running 1-3 days per week, embedded in your leadership team and drawing on deep experience in regulated mid-market businesses.
We typically start with a Breathe engagement (5-10 working days) to map capabilities and build the roadmap, then move into Grow for ongoing strategic leadership. That gives you a clear plan before you commit to an ongoing engagement and gives us the context to be immediately effective.
If you are weighing up whether a fractional model would work, the easiest way to find out is a conversation, so Get in touch, CTO to CTO.
If you are weighing the wider leadership question rather than the AI role alone, we have also compared fractional and interim CTO models.
