About Martin

Entrepreneur and interim executive with a decade of P&L responsibility. I built optilyz from an idea to Europe's leading platform for direct mail automation, leading it as sole CEO through growth, internationalization, and into sustainable profitability.

My foundation is a rare combination: the entrepreneurial vision of a founder, the analytical sharpness from strategy consulting and private equity, and the experience of leading a company internationally, lean, and KPI-driven. I think in terms of P&L and long-term value, while staying close to the product, sales, and people.

As an interim executive and advisor, I support companies where I have learned the most myself: modern B2B sales up to enterprise level, digitalization and AI-driven efficiency, as well as financial processes and controlling. A recommendation is only valuable to me when it has been implemented.
