Fractional Head of AI · Fractional CPTO · Paris, Brussels and remote

Your AI use cases are identified. Now they need to be delivered.

The portfolio exists. Initiatives multiply, sometimes twice over. Each team builds its own agent, and IT discovers the projects when it is time to secure them. A Fractional Head of AI sets up an AI programme under IT governance: prioritising use cases, delivering the first solutions and preparing your teams to take over.

On va parler franchement.

YOUR USE CASES. WHO OWNS THEM?

The business.They have the ideas.

IT.It has the framework.

The tech teams.They have the platform.

Without a bridge between them, every idea starts from scratch.

ONE PROGRAMME. ONE BRIDGE.

Scope.Roles, processes, prioritisation.

Deliver.Prototypes, tests, integration, production.

Hand over.Your teams take over agents and components.

Things worth saying

A use-case portfolio delivers nothing on its own.

Initiatives multiply. Some do the same thing.

I set up a single entry point: every idea is qualified, compared with what exists and prioritised by its value to the business.

Each team builds its own agent. Nothing is reused.

Agents and components are designed to serve several use cases. A shared catalogue avoids rebuilding what already exists.

IT discovers projects when it is time to secure them.

Architecture and security are part of scoping from day one. I work with the CISO and architects, within your standards, including ISO 27001.

The executive committee expects results. The business expects tools.

I connect the executive committee, IT, the business and tech leads. Every use case delivered is tied to a tracked metric.

What I have already done

Scope. Deliver.
Hand over.

Scope · Dotworld · SaaS venture studio · Lausanne

Chief Product Officer on the executive committee.

I built the product organisation, hired the product owners and defined design and delivery methods with the CTO, across several products at once.

Four new SaaS products and four major extensions delivered in under six months.

Deliver · Home Partners of America · Blackstone group · Chicago

AI in the customer service of 30,000 homes.

I led the AI transformation of support: listening to calls, mapping journeys, choosing use cases, then gradually deploying an assistant and prepared replies in Zendesk.

46% of tickets handled without an agent, and resolution time cut by 60%.

Hand over · Missions Publiques · ClairAI engagement

A non-technical team that now develops its own app.

ECP Companion serves a European citizens’ panel in 24 languages. In three months: audit, architecture, fixes, 176 pull requests reviewed and explained, and a way of working the team keeps.

Before that, at Sopra Steria for Eurocontrol: pilot machine learning tools for air traffic controllers, in an environment where traceability and verification are essential. Today, I also design and run my own products, such as SquareTally and CrowdMate. See the projects →

The ClairAI offer

An AI programme that prioritises, delivers and is handed over.

I take responsibility for the AI programme with leadership and IT: operating model, roles, processes, rituals, backlog and prioritisation. With your teams, I deliver the first prototypes, then their integration and production. I work in your Microsoft 365 and Copilot environment, within the group’s architecture and security framework.

An engagement starts with a two-week assessment, then two to three days a week for three to six months. Scope, pace and format, fixed price or time and materials, are set in writing before we start. I work directly or through the consulting firm that introduces me.

Let’s talk about your AI programme

How we work

You see what is moving forward.

01
I run the assessment in two weeks.
Use-case portfolio, ongoing initiatives, technical platform, architecture and security rules. You receive a reasoned prioritisation and the proposed operating model.
02
I set up the programme.
Roles, processes, rituals and backlog, agreed with IT. A clear path for a business idea to become a qualified use case, without slowing teams down.
03
I deliver the first use cases.
Fast prototypes on real data, tests, integration into the information system and production. Agents and components are documented for reuse.
04
I hand over.
Your tech leads and teams take over the programme, the agent catalogue and the methods. The handover is gradual and planned from the start.

“A use case counts when it is in production and someone uses it.”

I talk to the executive committee in the morning and open the code editor in the afternoon. Decisions made in committee reach the code intact, and what is delivered respects the framework agreed with IT.

Let’s get acquainted

We should talk if…

This sounds like you.

You have identified a first portfolio of AI use cases and want to speed up their delivery.
Several teams launch AI initiatives in parallel and IT wants to keep control.
Your solutions must comply with an architecture and security framework, notably ISO 27001.
You are a consulting firm looking for someone who structures and delivers.
You have raised funds and no senior product or technical leader runs the team.

Let’s be clear.

You only expect a study: the engagement includes delivery.
Nobody internally will take over the solutions: handover is part of the engagement, so teams are needed to receive it.
You need five days a week right now: then you should hire, and I can help you do it.

Nicolas Mathieu, founder of ClairAI, takes on the role directly: your contact on the executive committee, with IT and in the tech teams. See our founder’s background →

The questions that matter

What does that mean in practice?

What is a Fractional Head of AI?

A part-time head of AI. They set up and run the company’s AI programme: framework set with leadership and IT, use cases prioritised with the teams, delivery of the first solutions and handover to internal teams. With you, it is two to three days a week, with a real seat in decisions.

And a fractional CPTO?

The same format, for product and technical leadership: roadmap, team, technical choices and budget. It suits startups after a funding round and acquired companies whose products must converge.

How do you work with IT and the CISO?

From scoping onwards. The group’s architecture and security requirements are part of the prioritisation criteria. I work with the CISO and architects within your standards, including ISO 27001, with named access limited to what is needed.

Do you work in the Microsoft Copilot ecosystem?

Yes. I work in our clients’ Microsoft 365 and Copilot environments, with Copilot Studio for agents, following the integration rules set by IT.

What do you actually do on AI?

With the teams, I select the use cases that serve a metric, then put them into production: data, answer quality, costs, security and team adoption. At Home Partners of America, part of the Blackstone group, I led the customer service automation of a platform of more than 30,000 homes.

Can you work through a consulting firm?

Yes. A consulting firm can introduce me for an engagement with its client. Format, duration and everyone’s role are set in writing before the start. An investment fund can also introduce me to a portfolio company.

How long does an engagement last?

Usually three to six months, after a two-week assessment. The end of the engagement is prepared from the start: your teams take over the programme, or I prepare the person who will take the role.

Your use cases deserve to be delivered.
