Free, no card. And no sugarcoating.

Not a pitch. Just the problem, said plainly.

If you recognize your company in what I describe here, the audit will tell you exactly where you're stuck. Watch, then run yours.

The diagnosis

The founder-bottleneck has two faces.

Operational

Everything runs through you

Every deal, every sign-off, every exception. The company has a single pipe — you — and it backs up the moment you stop.

Decisional

You say yes to everything

Every yes is smart; their sum kills focus. The CEO's job is to say no to good ideas you don't need.

The 5 measurable signals. Count yours, honestly — 3 out of 5 or more, and the audit is for you.

1Everything comes back to you — sign-offs, trade-offs, exceptions. The company piles up waiting for you while you're on holiday.Operational
2More than 60% of your time goes into operations: closing, support, delivery, sign-off.Operational
3You say yes to everything: cash, good ideas everywhere, 4-5 initiatives in parallel. Focus dilutes.Decisional
4+20% investment → +5-10% revenue. Your unit economics are deteriorating: the fit is too fragile to accelerate.Economic
5Your numbers stay consistently below your projections — the sum of the other four.Downstream
Who it's for

This program isn't for everyone. That's the point.

It's for you if

  • You're the founder or CEO of a tech company between €500K and €6M ARR
  • Your company runs, but it runs because you're in it every day
  • You want to install a system, not collect yet another framework
  • You'd rather have an operator who's walked the path than a coach who's read about it

It's not for you if

  • You're looking for quick, one-off growth tactics
  • You're pre product-market fit or before your first €500K
  • You want to delegate the problem rather than change how you lead
  • You expect guaranteed revenue promises in percentages
The journey

From founder-bottleneck to system-led CEO, in 90 days.

Five modules that install in order. We start from your audit — it personalizes everything that follows — until you're steering the system instead of being inside it.

1

FounderOS Audit

We open the hood: you, the team, the business model, the P&L, the KPIs. A clear map of your real bottlenecks.

2

Direction OS

A direction no one can misread. We cut strategic sprawl and keep the bets that matter.

3

Revenue & Profit Engine

The engine for profitable, repeatable growth: pricing, margin, acquisition, conversion, retention.

4

Velocity Execution System

Decisions turn into results. Ownership, cadence, scorecards — the team moves without escalation.

5

CEO Pilot OS

You go from lead operator to system pilot. You lead by the numbers, not by tasks.

B

Point B

The company decides, executes and grows profitably — even when you're on holiday. An asset, not a job.

Point A · today

You are the system. Everything runs through you.

Point B · in 90 days

You steer the system. It runs without you.

Thibaut Vanderhofstadt

An operator who's walked the path, not a coach who's read about it.

Co-founder & CEO of Sortlist for 11 years: from 0 to €10M ARR, €11M raised, 3 M&A closed, 9 European markets. I built the system that grows a company without it depending on its founder.

And I paid full price for every lesson: health, family, trust. FounderOS is what I wish someone had installed for me ten years earlier.

The Sortlist team — 9 markets, 100+ people. The system scaled, not the chaos.

People who've worked with me

Not made-up client testimonials. People who've seen me operate.

Former Sortlist colleagues — verifiable on LinkedIn.

“A hard worker like I've rarely seen: he gives 100% to his project and knows how to surround himself with talented people. A CEO who combines genuine humanity with sharp analytical rigor and a customer obsession. He knows how to get the best out of everyone.”

“What struck me most was how involved he was — strategically and personally. After a conversation with Thibaut, you leave more motivated, more aligned, with a much clearer vision of where the company is going.”

Proof of system

A track record documented, not narrated.

I forged these methods in the field, with the real numbers. Four cases, published in detail.

Pricing

The migration that saved the company

+40% annual growth, operational profitability — the best financial position in 11 years.

Expansion

An OS replicated across 9 European markets

9 active markets, presence in 140+ countries, team grown to 100+. The system scaled — not the chaos.

Leadership

Restructuring from 130 to 75 without breaking the company

Company stabilized, back to +40% growth and profitability in 18 months.

M&A

Two acquisitions integrated — Spain and Germany

From zero to DACH market leader in a few months. European leadership confirmed.

How it works

You start with the audit. The rest, you decide later.

No barrier to entry: you run your audit, you see clearly, and you decide for yourself whether — and how — you want to go further.

1

Run your audit

You create your account and answer the FounderOS audit. You first, then the team, the business model, the KPIs. A few minutes, on your own.

Free
2

You see your bottleneck

You get your first read: where you're stuck, what's costing you margin, and where you remain your company's single point of failure.

Free
3

You go further, or not

Your free audit already gives you a real read. If you want to dig deeper, the full audit and a conversation with me are open to you — when you decide, never before.

And after your audit?

You stay free. Seeing clearly costs nothing.

The free audit already gives you a real read on your bottleneck. If — and only if — you want to go further, two options will open from your account: the full, more detailed audit, and a live conversation with me to talk it through. No pressure, no card required to start. You decide once you've seen.

And if you join a cohort later, the full audit is credited toward your program.

The cohort

8 founders per cohort. Not one more.

The limit is physical: beyond 8, I become the bottleneck. Each cohort fills by application — and the next one opens soon.

Your bottleneck won't fix itself by thinking about it. It gets fixed by seeing it.
