Does This Sound Familiar?

You work harder than ever. The business isn't moving fast enough.

  1. S/01

    Revenue grows, but profit doesn't.

    You're busier than ever and the top line is up — yet EBITDA is flat or compressing. Volume is hiding a margin problem.

  2. S/02

    You know prices should increase, but fear customer resistance.

    Every CEO knows where the pricing leak is. Almost none act on it. The fear costs more than the move ever would.

  3. S/03

    Your managers escalate problems instead of solving them.

    The leadership team brings you decisions, not outcomes. Your calendar fills with other people's judgement calls.

  4. S/04

    Execution is inconsistent and accountability is weak.

    Strategy is clear in the boardroom. By the time it reaches the line, it has been re-interpreted three times. Results vary by who's in the room.

  5. S/05

    The company depends too much on you.

    When you leave for two weeks, things drift. When you leave for two months, things break. The org chart says CEO. The reality says single point of failure.

  6. S/06

    Growth has stalled and you're not sure why.

    Last year's playbook isn't working. Hiring more salespeople isn't fixing it. You suspect the problem is structural — you just can't name it yet.

I've Seen These Problems Before

Eleven consecutive transformations. The pattern is always the same.

Three decades leading businesses across Europe and North America — turnarounds, growth transformations, and private-equity-backed companies. Different sectors, different sizes, the same handful of constraints every time.

The good news: these problems are solvable — when you have the right operating disciplines in place.

  • P/01Growth without profitability
  • P/02Weak pricing discipline
  • P/03Leadership bottlenecks
  • P/04Poor execution and accountability
  • P/05Organizational complexity
  • P/06Strategic drift
The Business Diagnostic

Stop guessing. Diagnose first.

Fifteen questions. Seven minutes. The Business Diagnostic identifies exactly where the gaps are in your business — growth, profitability, leadership, execution, or strategic drift — and tells you which Operating System I'd recommend you fix first.

The Plan

The Business Performance OSTM

Six management systems, not six frameworks. Each one removes a constraint I've watched break otherwise good businesses. The Performance OS is the framework I install when I work with leadership teams — and the body of practice I walk through on YouTube for operators who want to start on their own.

Why Leaders Work With Me

Businesses don't fail from lack of administration. They fail from lack of management.

Most advisors give you Administration: meetings with KPIs, decks, spreadsheets. That's the Noise.

Management focuses on the people creating the value — judging, deciding, training them to do the same. That's the Signal.

Welcome to the zero-complexity, actionable reality of execution.

The Operator

Three decades inside the businesses most consultants only diagram.

CEO and COO across eleven consecutive transformations for American and European private-equity funds — industrial, B2B services, and international operations. Now: a handful of CEO advisory engagements a year, plus the Operating Systems I built along the way.

Common Questions

Fit, scope, format.

Q.01
Does it work for an SMB? Or only large groups?
Yes — both. The Operating Systems scale down to a €1M owner-led shop and up to a €200M PE platform. Same disciplines, different cadence.
Q.02
Does it work for B2B? Or only B2C?
Yes — both. Eleven consecutive turnarounds across industrial, B2B services, distribution, and consumer brands. The constraints rhyme even when the products don't.
Q.03
Does it work for manufacturing? Or only services?
Yes — both. The case studies are weighted toward industrial groups because that's where I spent the last decade — but every Operating System has been installed in services businesses too.
Q.04
Does it work internationally? Or only in one market?
Yes — both. The work has spanned North America, Western Europe, and cross-border platforms. Four working languages. The disciplines travel; only the local nuance changes.
Q.05
Who do you work with?
CEOs, owners, managing directors, and PE-backed executives running €1M–€250M businesses. Industrial, B2B services, and PE portfolio companies. Operators who want frameworks they can actually run — not slideware.
Q.06
What is the Business Diagnostic, exactly?
A 15-question self-assessment scored across five performance axes: growth, profitability, leadership, execution, and transformation risk. You receive a written profile and a recommendation for the single Operating System that will move the needle fastest. Free, no call required.
Q.07
What is the Performance OS?
Six interlocking management systems — Revenue Growth, Pricing, Leadership, Execution, Transformation, and Value Creation — built from three decades of operating experience. It's the framework Michel installs when he works directly with leadership teams. Each system also has a companion YouTube playlist for operators who want to start on their own.
Q.08
How is this different from a McKinsey/BCG engagement?
I'm one operator, not a deck factory. You get the person who has actually run the P&L, made the hard calls, and lived with the consequences. Less polish, more conviction, one fraction of the bill.
Q.09
Do I have to talk to sales to take the Diagnostic?
No. Take it on your own. Read the result. If a program fits, you'll know — and you can move forward without a call.
