About Marie Sophie

Fractional CFO & Systems Thinker for startups & scaleups.

Your growth creates complexity.
At some point, optimizing individual areas is no longer enough. You need someone who sees the whole picture.

I combine finance, processes, decision logic, and AI into a system that supports you. And it's tailored to you. Because every company has its own character. No blueprints to squeeze your business into.
Some work with me once. Others work with me permanently as operational support or as a sparring partner for strategic decisions.

For you, this means:
You know the real cost of your decisions. You know how long your money will last. You can enter investor discussions without faltering. And your growth remains controllable even when it accelerates.

No matter what stage your business is in. Whether you're validating a model, preparing your first investment, or in the midst of scaling.

I test reality. I don't reinforce illusions.

If you notice that your growth is slowing you down:
Let's talk briefly.

Typical process:
• Create transparency
• Build control logic
• Anchor and hand over structure

Typical case:
A rapidly growing startup or scaleup without a solid financial structure – decisions are made intuitively rather than based on clear numbers.

    I come into play when startups and scaleups grow, but the control system can't keep up.

    When there are numbers, but no clarity emerges.
    When decisions need to be made, but there's no solid basis.

    That's exactly where I start.

    I build finance structures that make companies controllable in the first place.
    From transparency and clear KPIs to reliable decision-making foundations.

    Not as a permanent operational role,
    but with the goal of creating a system that works even without me.

    So that growth doesn't become a risk
    and a CFO can eventually work effectively.
