These Greek companies with a mobile app are primarily large groups in telecommunications, finance, retail, and hospitality. Key players include OTE Group of Companies, a major telecom provider; Eurobank, a strong financial organization; Aegean Airlines, a full-service airline; and Ikos Resorts, a hospitality group. These firms showcase the breadth of established industries adopting mobile technology.
A notable pattern among these companies is their geographical concentration. Most, including National Bank of Greece, Alpha Bank, and INTERAMERICAN, have their headquarters in Athens. This indicates a strong centralization of major business operations and technological development within the Greek capital.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
