About

Entrepreneur with 25 years of experience in venture capital, company building and technology investing. I have worked closely with founders across the full lifecycle of digital businesses — from early product definition to financing, scaling and governance. In 2023, I deliberately returned to hands-on product creation. I architect and build software on Apple platforms, combining product thinking, technical depth and long-term business perspective. I designed and engineered Script Buddy, my first fully self-built Apple platforms product, taking it from concept to live App Store release — covering product and software architecture, UX design and go-to-market strategy. Beyond technology and investing, I am a passionate skier, mountaineer and ocean sailor, having crossed the Atlantic twice on our sailing yacht Starship.
