About

When performance no longer matches potential.

I lead at the intersection of business, finance and AI-driven operating systems — designing organizations where technology, automation and human expertise work together to deliver scalable, high-performance outcomes.

My background is that of a senior business leader: strategic vision with execution discipline, always grounded in P&L ownership and value creation. I operate with an investor mindset — bringing clarity to complex environments, structuring what lacks direction, and deciding under uncertainty.

As a founder, I built an AI-native business from the ground up. That experience shaped my conviction that the next generation of companies will be defined by how they redesign their operating models around AI.

Sixteen years across enterprise software (11 at Temenos, Finance Director EMEA-LatAm Cloud SaaS through Revenue Growth & Sales Ops Director in Dubai), founder of an AI-native company, based in Geneva. Local and international leadership · start-ups to global organizations · cross-industry (retail, chemicals, enterprise software, technology) · full lifecycle from creation to transformation · M&A and integration · governance and advisory · investment mindset.
