The story of Diamantis Masoutis S.A. began in 1976, when Diamantis Masoutis established the first Masoutis supermarket in Thessaloniki, at Antigonidon Square. Since then, the company has demonstrated consistent and dynamic growth, gradually expanding its network—initially within Thessaloniki and later across Northern Greece—through both organic development and strategic acquisitions. In 2018, it entered the Attica region with the largest acquisition in its history at that time, and in 2022, it further strengthened its presence in Corfu, Crete, and the Aegean islands through a strategic partnership.

Fifty years later, in 2026, the company operates a network of 400 stores across multiple regions of Greece, employing over 11,000 people. The company is the market leader in Northern Greece and ranks among the top retail enterprises nationwide. It is a Greek family-owned business with a solid financial foundation and a strategic focus on sustaining positive growth.

The company invests in technology, innovation, and infrastructure. Its Information and Communications Technology systems ensure business continuity, data security, and a high level of protection. It operates one of the most modern Distribution and Warehousing Centers in Greece and the wider Balkan region, located in Kavallari, Thessaloniki.

Through its continued expansion, Diamantis Masoutis S.A. creates employment opportunities, supports the Greek economy, local communities, producers, and domestic products. It also implements impactful corporate social responsibility initiatives that benefit society and the environment.

Masoutis supermarkets have established a reputation as the “affordable and Greek” choice, consistently delivering high-quality, safe products across a broad assortment at competitive prices.
