About the group

One vision, three exceptional crafts

MY INVEST GROUP is a French heritage holding founded in 2020 by Ylies Mehidi, dedicated to luxury real estate and high-end interior craftsmanship. Headquartered in Neuilly-sur-Seine, the group operates in Paris, throughout Île-de-France and across France, bringing together three Maisons with complementary expertise — each cultivating the demand for bespoke craftsmanship and a passion for fine work.

From the renovation of Haussmann-era apartments to prestige real estate development, through to the creation of natural stone Mobilier d'Art (marble, travertine, onyx, granite), every pillar embodies a single promise: transforming raw material into heritage, and projects into legacy.
