C lemente Del Vecchio is one of the world's youngest billionaires, having inherited his vast fortune after the death of his father, Leonardo Del Vecchio, in 2022. His father was the visionary founder of Luxottica, the company he built from a small workshop into the world's largest eyewear manufacturer, which later merged with Essilor to form the global giant, EssilorLuxottica.

Upon his father's death, his massive fortune, held through the Luxembourg-based holding company Delfin, was divided equally among his six children and his widow. Clemente, being one of the youngest children, inherited a 12.5% stake in Delfin, making him a multi-billionaire as a teenager. Delfin is the largest shareholder in EssilorLuxottica and also holds significant stakes in the Italian bank Mediobanca and the insurer Generali. Clemente is not involved in the management of the family's vast business empire.
