Isabel Marant is owned by Montefiore Investment.

Parisian luxury fashion house founded by designer Isabel Marant, who began her career with a knitwear label called Twen in 1989 before presenting her first collection under her own name in 1995. The brand became associated with an effortless Parisienne aesthetic blending bohemian and sportswear influences, and launched the accessible diffusion line Isabel Marant Étoile in 2000. Montefiore Investment acquired a majority stake in 2016, with Marant and her founding partners retaining 49% of the company.
