Alexandre Mattiussi

Alexandre Mattiussi (born September 15, 1980) is a French fashion designer and entrepreneur who is the founder of AMI, a French luxury ready-to-wear menswear brand. He previously designed for Dior Homme, Givenchy, and Marc Jacobs.

Born and raised in Normandy to an Italian father and a French mother, he founded AMI in late 2010 and presented its first collection in 2011. He won the ANDAM Grand Prize in 2013 and presided over the competition's jury in 2026.

Early career Mattiussi was born on September 15, 1980, and grew up in Normandy; his father was Italian and his mother French.

He went on to work for Christian Dior 's "30 Montaigne" men's line, Givenchy as first assistant for men, and Marc Jacobs.

He spent more than five years at Givenchy, where he specialized in men's tailoring, and afterwards worked on the Marc Jacobs men's line, dividing his time between Paris, Milan and New York.

AMI Paris In late 2010, he founded AMI Paris, quickly gaining international success. In December 2012, the brand opened its first boutique in Paris. The label's name combines the designer's initials with the last letter of his surname, and is also the French word for "friend," a reference to his stated aim of dressing his own circle; the full brand name adds "Paris." In 2016, he became a member of Fédération de la Haute Couture et de la Mode. Mattiussi extended the label to womenswear in 2018. In 2024, that had grown to more than 60 standalone stores and more than 700 points of sale. At the time of the deal the company reported annual revenue above €50 million, more than 50 percent higher than the previous year.

AMI took its first outside investment in 2012 from the Mode et Finance fund backed by Bpifrance, followed by a round led by Neo, and added the London firm Felix Capital as a shareholder at the end of 2022.

AMI's headquarters occupy a building on the Place des Victoires in Paris that Mattiussi first visited in 2011, before the label existed, and the brand showed its spring 2026 collection on the square itself, with models circling the statue of Louis XIV at its center. In June 2026 the label opened a store across the square from its offices, pairing a ground-floor retail space with a second-floor showroom, and Mattiussi curated a selection of vintage design objects and photographs to show alongside the collection. In 2024, he directed the music video for the single "Où tu ne m'attendais pas" by Isabelle Adjani with Christophe (posthumously).

Awards and recognition Mattiussi received the ANDAM Grand Prize in 2013, presented to him by Pierre Bergé.
