Industry & regional structure

Industries. Tourism and hospitality, shipping, agri-food and a broad small-services sector lead.

Regions. Attica (Athens) dominates, with Thessaloniki and the island and coastal tourism economies.

Official register sources

The legal source of truth for Greece is GEMI. It records every legally trading company — identifier, status, address and often officers and filings — which is why it is the most complete and current starting point for prospecting. See the full register directory.

The blind spot in stored B2B databases

Aggregators like Apollo and ZoomInfo fill their warehouses from contributory networks, purchased data and scraping, a model that over-represents firms maintaining a strong English-language footprint online. A small Greek tourism operator is in GEMI and on its Greek-language site, but thin in a US-built warehouse.

Company data in Greece: registers & coverage

In Greece the authoritative company record is GEMI — the General Commercial Registry (Γενικό Εμπορικό Μητρώο) — searchable through the gov.gr business portal at businessregistry.gr. Every sole proprietorship, partnership, limited-liability company and société anonyme that trades legally is entered there, while the AFM tax number issued by the tax authority is the identifier most used in day-to-day commercial dealings. GEMI is therefore the most complete and current starting point for prospecting Greek firms.

Two features make Greece distinctive. First, shipping: the Greek-owned merchant fleet is the largest in the world by tonnage, run not by a handful of conglomerates but by a deep field of privately held, often family-led SME operators where the owner is frequently also the CEO. Second, tourism and hospitality anchor a vast base of small, seasonal businesses across the islands and the mainland. That structure is what stored databases miss: a small Cycladic hotelier or a Piraeus ship-management office is fully documented in GEMI and on a Greek-language website, yet stays thin in a US-built warehouse that indexes English-language, online-first companies.
