What I do

CFO depth,
without the overhead

Every engagement is different. What stays constant is the quality of thinking: strategic where it needs to be; hands-on where it matters most.

02
Financial Controlling

Budget vs actual, variance reporting, cost centre management, and KPI frameworks that drive real decisions.

Real visibility into where your cash is going and where it will be. 13-week rolling forecasts and scenario planning.

Financial Planning & Analysis

Forecasts that move with your business

Rolling forecasts, scenario modelling, and budget vs actual analysis built to give leadership a real-time picture. I use machine learning to surface patterns in your historical data faster than any spreadsheet allows; the interpretation, the assumptions, and the recommendations remain mine. The model accelerates the work. The judgment behind it does not change.

Commercial & Marketing Analytics

Finance meets commercial performance

Revenue does not start at the P&L; it starts at the top of the funnel. I bridge the gap between marketing spend and financial outcomes, so you know exactly which channels drive profitable growth and which ones simply drive cost.

CFO level depth

I started in accounting eighteen years ago, not because it was the easy path, but because I wanted to understand how businesses truly work from the ground up.

Over the years I moved through controlling, financial management, and into CFO-level roles across industries that could not be more different: travel tech, alternative investments, media, digital assets, and SaaS.

Today I combine that experience with AI and automation, not as a trend but as a genuine multiplier. I use tools like Claude by Anthropic to handle the repetitive: data processing, first-draft narratives, pattern detection. I handle the irreplaceable: judgment, stakeholder communication, and the calls that cannot be automated; the result is CFO-level thinking delivered faster than you would expect.

Based in Hamburg, Germany, and available across the DACH region and beyond; in English, Spanish, and German.
