Utrecht-based. On-site within 3h: NL, BE, LU, DE, FR.
Code reviews, ADRs, workshops — I stay until it's done.
French-born entrepreneur turned senior architect. 9 years as Founder & CTO of Exxan France — 0 to 12 people, 0 to €700K revenue, with clients like L'Oréal, Thales, and Peugeot. Today I lead architecture transformation at NS (Dutch Railways) and take on select Fractional CTO engagements for ambitious SMEs.
I don't believe in architecture for its own sake. Every decision I make has to serve the business — today, and in 3 years.
30-minute call. No pitch. Just a conversation to see if we're a fit.
I’m Laurent Demouge, senior IT architect and transformation expert.
I help ambitious companies — from fast-growing scale-ups to established enterprises — design and transform their software architecture to support their growth, agility, and long-term impact.
Whether you’re building your platform from scratch or modernizing legacy systems, I provide the strategic and technical expertise to align your IT foundations with your business goals.
No 120-slide PowerPoint decks. No big-bang rewrites that never finish. Just architectural decisions that serve your business.
I’ve worked with: NS (Dutch Railways) · L’Oréal (digital supply chain) · Thales (critical systems) · Mazars (IT transformation)
From critical infrastructure to growing SMEs: I know what “pragmatic” means: deliver value today while building foundations for tomorrow.
You don’t have infinite VC runway to “figure it out later.”
You need technology that works now and scales later — not the other way around.
I work with pragmatic European companies that want to deliver value today while building foundations for tomorrow.
I’m based in the Netherlands and work across Belgium, Luxembourg, Western Germany, and Northern France.
Amsterdam, Brussels, Cologne, Lille — if you’re within 3 hours, I can be there for the moments that count: strategic workshops, critical architectural decisions, team alignment.
Face-to-face matters when building your company’s technology foundations.
I don’t drop a report and disappear.
I work with your team: code reviews, pairing, ADR (Architecture Decision Records), workshops, mentoring.
The right architectural decisions come from understanding your context, constraints, and goals — not from applying trendy frameworks.
Start-ups & scale-ups who want to build solid architectural foundations from day one and move fast without breaking everything.
SaaS and product teams needing external support to scale safely and efficiently.
Established SMEs (50-500 people) digitalizing their operations and needing tech leadership without hiring a full-time CTO.
Large enterprises facing legacy system modernization or architectural alignment across departments.
Technical leaders who want to challenge, validate, or refine their roadmap with an experienced architect.
A clear and realistic architectural vision adapted to your context and constraints.
Pragmatic execution aligned with your business objectives, not with the latest tech trends.
Concrete collaboration with your teams: code reviews, pairing, ADR, workshops, mentoring.
Long-term value through architectural decisions that give you flexibility, not rigidity.
No sales pitch. Just a 30-minute conversation to understand your situation and see if we’re a fit.

Book a call →Unlike big consulting firms that send junior profiles and disappear after delivering a slide deck, I work directly with your teams — hands-on, embedded, outcome-focused. You get senior expertise from day one, without the overhead.
Typically within 1–2 weeks. I keep capacity available for new engagements and adapt to your timeline.
For a Technical Diagnostic or Due Diligence, engagements start from 2–3 days. For Fractional CTO or Architecture Assessment, a minimum of 3 months is recommended to deliver real, lasting impact.
Both. I'm based in Utrecht (Netherlands) and available on-site within 3 hours: Netherlands, Belgium, Luxembourg, western Germany, northern France. For other locations, remote works well with occasional on-site sessions for key moments.
My primary area is Benelux, western Germany, and northern France — all reachable within 3 hours from Utrecht. I also work remotely with clients across Europe.
