With roughly 280,000 companies on the CRO register, Ireland runs two business worlds at once — a world-famous Dublin cluster of tech, pharma and financial multinationals, layered over a dense base of small indigenous firms in Cork, Galway and Limerick.
Industries. Technology and software (Dublin's MNC cluster), pharmaceuticals, agri-food and financial services lead.
Regions. Dublin dominates, with Cork, Galway and Limerick as the main regional hubs.
The legal source of truth for Ireland is CRO. 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.
Stored databases such as Apollo and ZoomInfo are built from three sources — shared user contacts, bought lists and web scraping — each tilted toward companies with a visible, English-language web presence. A small Cork engineering firm is in the CRO and on its own site, yet thin in a US-built warehouse weighted toward the Dublin multinationals.
| Segment | Share of firms | Online-footprint coverage |
|---|---|---|
| Large + MNC | ~2% | Good — usually covered |
| Small (10–49) | ~6% | Variable — partial |
| Micro (1–9) | ~92% | Weak — under-represented |
Irish companies — overwhelmingly small indigenous firms outside the MNC cluster — are likely under-represented in online-footprint databases. A structure-based estimate, not a figure measured from any database.
Ireland keeps a single authoritative company record: the Companies Registration Office (CRO), whose CORE portal at core.cro.ie lets anyone look up a company's CRO number, registered address, status, directors and filed accounts. The register holds roughly 270,000–280,000 companies, with new incorporations running above 20,000 a year. Structurally the market is two economies in one — a globally visible cluster of multinational technology, pharmaceutical and financial-services operations around Dublin, sitting on top of a far larger base of indigenous micro and small firms in Cork, Galway, Limerick and the rural counties.
That second layer is exactly where bought databases thin out. Apollo, ZoomInfo and similar warehouses lean on English-language web presence and US-contributed contacts, so they over-index on the Dublin multinationals while a five-person Galway agri-tech firm or a Limerick engineering subcontractor is in the CRO yet barely anywhere else. Because Irish SMEs file with the CRO but rarely maintain rich corporate websites, reading the register and its filings directly is the only reliable route to that long tail.
