Tech and Data/AI advisory, interim CIO and CDO, Tech Due Diligence

Hands-on Tech, Data/AI advisory and interim leadership

I build.
I bring back control.
I deliver.

I have spent thirty years leading IT and Data/AI functions as CIO, CDO and CTO. Today I work as an advisor or as an interim executive, with one rule: hands-on advice that goes all the way to results. Companies call me to build an organisation from scratch, take over a programme that has gone off track, or see a major transformation through to the end.

Three situations where companies call me in.

Build from scratch

An international bank with no Data/AI organisation: no team, no governance, no strategy. Within 24 months the Data Office was running, generative AI was in production, more than 200 people had been trained and the Board had signed off the strategy.

Organisation built from scratch

Bring back control

A European asset manager in the middle of a full IT overhaul, with 100 people to reorganise and 10,000 person-days to manage. Within 8 months the budget was back on track (−€400K), the ERP was live in 5 countries and month-end close was 10 days faster.

Turnaround in 8 months

Cut costs & create value

An international media group, with €50M in IT savings over the mandate: Cloud rationalisation (−30%), outsourcing renegotiation (−€800K a year), digital supply chain (+€1M) and M&A due diligences on legaltech and fintech targets.

What I have done , and where.

Six sectors, thirty years in the field.

I mostly work for three kinds of clients.

Private Equity Funds

Partners & Portfolio teams

You invest in companies whose value depends on their Tech and Data/AI maturity. I help you avoid bad surprises and speed up value creation.

Tech Due Diligence in 10 to 15 days: red flags, technical debt, contractual risks, with a clear report before closing.

100-day plan after the deal: stabilise, set the Tech and Data/AI roadmap, go after the quick wins that move cash.

Carve-out and carve-in: separating or integrating IT, framing TSAs, getting Day 1 ready and keeping stand-alone costs in check.

Interim CIO or CDO: I take over operations, handle investor reporting and prepare the exit.

Exit preparation: KPIs, Tech value story, documentation for buyers.

Executive leadership

CEOs, CFOs, mid-market leaders

You are accountable for the company's performance, and Tech and Data/AI should help you deliver it. As an advisor or as an interim executive, I work alongside you as part of the leadership team rather than as a visiting consultant.

Taking back control when a project slips, a budget runs away or IT stops delivering.

Data/AI transformation, with measurable results in production.

Interim leadership: I hold the CDO or CIO role while you recruit, with no break for the teams.

Advice on five value-creation levers: digital strategy, IT, CRM, data-driven management and technology investment.

Business leaders

Operations, Finance, Marketing, Risk, Compliance

You own a business project that depends on Data/AI or a new system, and you need someone who can talk to your teams as easily as to IT and vendors. I scope the need, run the delivery and make sure the tool actually serves the business.

Scoping a business Data/AI project: use cases, expected gains, choice of solutions.

Running the programme on the business side, working with IT, vendors and integrators.

Regulatory compliance (GDPR, DORA, BCBS239, Solvency II) with processes your teams can actually sustain.

Performance management: reliable KPIs, dashboards, faster close.

How an engagement works.

Read the situation

I start by listening, and by looking at the architecture, the contracts and the teams. After two weeks I have a clear view of the situation.

Decide & plan

Then come the hard decisions: stopping a project, changing a vendor, reorganising a team. All of it in a costed, dated plan with milestones everyone can follow.

Execute with the teams

I'm on the ground with the teams, challenging vendors and managing risks day to day. I'm as comfortable with developers as I am with the Board.

Sustain & hand over

The engagement ends when the organisation runs without me, with documentation, training and governance in place.

AI · LLM

Are LLMs corrupting your documents?

25% degradation after 20 unsupervised delegations. It's a stress test, and here is what it really means for production.

What people ask me most.

What is an interim Tech and Data/AI executive?

An experienced executive who takes a leadership role (CIO, CDO, CTO) for a limited period with a clear objective. They are effective from day one and leave once the job is done.

Who do you work for?

Private Equity funds and their portfolio companies, executive teams and mid-market leaders, and business leaders who own a Data/AI or IT project.

What kind of engagements do you take on?

Tech Due Diligence, IT carve-outs and carve-ins, 100-day plans, interim CIO or CDO roles, Data/AI transformation, and hands-on advice on strategy and technology choices.

Advisory or interim management: what's the difference?

As an advisor, I work part-time: I scope, help you make the calls and support your teams through delivery. As an interim executive, I take the role full-time and own its results. Either way, no report that ends up in a drawer: I commit to what has to work in production.

Which sectors do you work in?

Banking and wealth management, insurance and mutuals, media, telecoms, as well as SMEs and startups as part of M&A deals.

Where do you work?

In Paris and across Europe, in French or English.

How do we get started?

With a first confidential conversation, by email or phone. We go over your situation and I'll tell you honestly whether I can help.
