Leadership that inspires - Strategies that deliver
HOW IT ALL BEGAN
Every transformation begins with a bold decision.
My journey started with a passion for turning complex business challenges into growth opportunities. As a former CEO of large-scale international organizations and now founder, investor, and strategic advisor, I bring years of hands-on experience in business transformation, leadership development, and cultural reset.
I specialize in guiding companies through critical transitions — from post-exit phases and strategic redirection to building high-performing executive teams. My mission is clear: reset strategy, reinvigorate culture, and strengthen leadership to unlock sustainable impact.
Whether I step in as an (interim) CEO, a strategic advisor, or a founder, I bring energy, clarity, and results.

Great leadership isn’t about authority
It’s about vision, purpose, and results
I don’t just advise — I deliver. Whether your organization is scaling up or already managing billions in revenue (been there), I bring clarity, energy, and execution power to the table.
