Biedronka
Jerónimo Martins · 1997
Biedronka is a Polish discount supermarket chain owned by Portuguese group Jerónimo Martins. It operates 3,730 stores in Poland, employs 84,000 people, and accounts for approximately 70% of its parent’s sales. Its model relies on high-volume, low-margin sales of local and own-label goods — not differentiation or premium pricing. Its sole international move — one store in Slovakia, opened March 2025 — shows no evidence of traction. Its strength is also its risk: extreme geographic concentration in Poland.
