Head of Supply & Business Development - Open to opportunities

Summary

Senior Hospitality & Luxury Travel Executive with 15+ years of international leadership experience across hotels, cruise lines and premium short-term rental platforms. Currently Head of Supply & Business Development at Le Collectionist, I oversee multi-country operations and growth strategies across Europe and ROW, with full ownership of portfolio performance, financial results and service excellence.

My expertise sits at the intersection of strategy, operations and people leadership: scaling high-end property portfolios, structuring cross-functional organizations, defining KPIs, budgets and roadmaps, and aligning Supply, Stay, Concierge, Sales, Marketing and Tech teams around ambitious growth objectives.

I bring a strong track record in market expansion, client relations, operational transformation and luxury brand positioning, consistently delivering above-target performance, high NPS scores and sustainable value creation.

Recognized for my hands-on, data-driven and collaborative leadership style, I focus on building resilient organizations that combine rigor, innovation and service excellence to meet the evolving expectations of global luxury travelers and partners.
