The Russian grocery chain founded in Krasnodar in 1994 is Magnit.
Magnit was established by entrepreneur Sergey Galitsky, initially through the company Tander. The business began in wholesale distribution before shifting toward a convenience-store model in the early 2000s. Its name, Magnit, means “magnet” in Russian, an idea suited to a chain intended to draw frequent neighborhood shoppers.
The retailer expanded rapidly across Russia, adding convenience stores, supermarkets, hypermarkets, cosmetics outlets, pharmacies, and other formats. In 2006, it developed its hypermarket chain, and in 2015 it became the first Russian retail chain to pass the 10,000-store milestone.
The red-and-white branding is a useful visual clue, but it should not be confused with Pyaterochka, another major Russian food retailer associated with the X5 Group. Lenta and Dixy are also Russian chains, yet the combination of Krasnodar origins, 1994 founding, and the Magnit name identifies this answer specifically.
