Adding luxury to your business — properly

Luxury Clementine is a London-based luxury consultancy and a trading name of Horizonius Ltd. Active in London since 2016, we help businesses of any size refine brand positioning, improve the customer journey, and introduce service standards that feel calm, consistent and premium — online and in person.

Founded by Yann M. Sevinti, Luxury Clementine is shaped by craft and commercial discipline. Yann grew up around his family’s luxury embroidery, leather and fashion business, where detail, finish and consistency were non-negotiable. He studied International Trade BAC and later completed a Master’s degree at the University of West London, combining strategic structure with an artisan mindset. As part of his university studies, he completed Erasmus in Germany, strengthening his German and developing cross-cultural fluency. In 2014, he further deepened his understanding of hospitality and luxury in Paris through the EU’s Erasmus for Young Entrepreneurs programme, collaborating within a restaurant environment where service standards and guest experience are refined daily.

About

Since 2016, Yann has designed and delivered high-end experiences in London — from corporate events to private celebrations — translating premium expectations into practical systems teams can uphold. Today, he also works internationally as a luxury consultant, helping brands and operators upgrade services to a luxury standard across hospitality, F&B, fashion and real estate.

Luxury is not about being expensive. It is about clarity, ease and care — delivered consistently. We help you build a premium standard through practical strategy and simple systems your team can use, including:

• Clear direction on what you offer and who it is for

• A smoother customer journey with less friction

• Service standards that protect quality as you grow

• Stronger trust and better-quality enquiries
