Laurent Tulpan: the person you meet is the one who does your work.
A developer, then a lead, a program manager and a CTO. He scopes every engagement, runs the fractional CTO work and takes the interim assignments inside IT departments himself.
- Founded Coeur du Web in 2019
- Started in corporate IT
- Paris, working across Europe

From corporate IT to your company: where the method you get comes from.
Three periods, one habit: every number checked before it is announced, every cutover written before it happens.
Media, telecoms, banking
Developer, then lead, then program manager inside corporate IT.
TF1 and Médiamétrie in media. Bouygues Telecom, Orange Business Services and SFR in telecoms. Crédit du Nord and BPCE in banking. That is where the method comes from: documentation, cutover plans, and steering committees where every figure is checked.
2019
Coeur du Web founded, to bring that method to smaller companies.
The bet: bring that discipline to companies too small to hire a full-time CTO, with the delivery risk carried in the contract rather than passed to the client. A deliberately small team of three senior engineers, two of whom have worked together for more than twenty years.
Since
Fractional CTO, interim leadership, and products of our own.
Fractional CTO engagements for growing companies, interim assignments inside IT departments that have lost a key person, and our own software products, which is how we prove we can carry software to a market rather than only ship a project.
The fractional CTO engagement
Engagements you can check, several of them public record.
French and Belgian public institutions among them, which means the work is a matter of record rather than a claim you have to take on trust. The numbers are on the case studies page.

Not a salesperson who sells, then disappears.
The person in your first conversation is the person who scopes the work, defends the architecture to your board and signs the handover. He also publishes his method openly, in French, on his personal site: practical guides on rebuilding a site without losing search traffic, and on scoping and steering digital projects.
His personal site, tulpan.net (in French)- From code to CTODeveloper, lead, program manager, then CTO.
- One named contactFrom the first video call to the handover.
What he writes, when the question is worth an article.
Making the case for technical debt without using the words technical debt
“We should rebuild this properly” never gets funded, and that is rational. Three ways to convert technical debt into delay, risk and money, so it competes with the requests that do get funded.
Read the articleWhat a fractional CTO costs, and the three ways it gets priced
Day rate, monthly retainer, fixed scope. The three models make your vendor optimize for different things, and the cheapest headline number is usually the most expensive arrangement.

20 minutes with him, not with a salesperson.
Tell us about your project. If we can help, he will say how. If someone else would serve you better, he will say that instead.
