Business & growth leader with 15+ years of experience across Europe and the U.S, building, scaling, and transitioning ventures with full ownership of strategy, teams, and outcomes. Based in Switzerland, I stepped into motherhood with two young children — a phase that sharpened my leadership to be focused, grounded, and outcome-driven. Now ready to fully re-engage in building corporate ventures and teams, I'm open to senior in-house roles (Business / Growth / Strategy Director); side activity: GutScalers, translating real scaling experience into gut & mind leadership.
