How It Works

Simple and direct — from your problem to a working solution.

3 steps from start to finish

No bureaucracy, no surprises

  1. You describe the problem — Tell me what decision is hard to make today, which number you can't trust, or which financial process is stuck. No technical form: just tell me the situation as it is.
  2. I run the diagnosis — I analyze what you have (systems, spreadsheets, ERP, data) and put together a proposal for how to solve it. I'm clear about what will be delivered, how long it will take and what I need from your side.
  3. You receive something that works — I deliver the dashboard, model or controllership structure actually running. Not a presentation — something you and your team can use every day.

What's different here

Compared to what you've probably already tried

Not a PowerPoint consultancy

I don't deliver reports full of recommendations that end up in a drawer. I deliver running models, updating dashboards and consolidated data — things that generate results starting tomorrow.

No IT required to run it

I connect to your existing data sources — ERP, spreadsheets, legacy systems. You don't need to change systems or hire an engineering team to use what I deliver.

Not a generic solution

Every project starts from scratch looking at your business. I don't apply a template from a previous project — because your company's problem is different from others.

Fast turnaround

Strategic diagnosis: 2–3 weeks. Functional controllership dashboard: 6–10 weeks. Larger projects are split into incremental deliveries so you see results early.

You stay in control

I train you and your team to operate what was built. The goal is that you don't need to call me every time you want a different number.

Full honesty

If the problem you bring isn't something I can solve well, I'll say so in the first conversation. I'd rather pass on a project than deliver something that doesn't work.
