Managing Partner

YOUCCOUNTING GmbH

At home in bookkeeping with heart and mind.

For over 14 years, I've been active in the financial world – from the tax office to medium-sized companies to international corporations.

Today, as Managing Partner of YOUCCOUNTING GmbH, I support companies in all phases: from day-to-day bookkeeping to annual financial statements to complex transformations and challenges. My focus is not only on the numbers but also on the people behind them.

I see bookkeeping as part of a larger whole – structured, forward-looking, and always solution-oriented. Whether it's classic bookkeeping, process optimization, digital transformation, or acting as a sparring partner in critical business phases, I bring not only experience but also empathy and structure.

In my career, I've been privileged to work with companies of all sizes and industries – from start-ups to billion-euro corporations, from craft businesses to international tech companies. This diversity is my daily drive.

YOUCCOUNTING stands for a modern, clear, and sustainable view of bookkeeping – and for the idea that every person in a company matters – both with us and for our clients. And that's how we live it – with passion, expertise, and the aim to make bookkeeping not just right but truly great.
