Supplier capability coverage

Information from public records only, not an endorsement, a qualification or procurement advice. Each capability names the evidence it rests on; check the source and the supplier before relying on it. No evidence recorded here does not mean that an organisation cannot supply a capability.

For each capability and each part of the parts tree: how many companies and organisations in the EU Member States have supply evidence (a procurement contract, a product the organisation documents, a product line on its own product page, or open-source software it develops), and in how many countries. Research activity is counted apart: taking part in an EU-funded project, or a technology area an editor confirmed, shows work on a topic, not that an organisation can supply it. A capability with one EU company with supply evidence, or none, is flagged. The flag describes the portal’s records, not the market: read it with the evidence and the other European suppliers.

Of 26 capabilities, 2 have no EU company with supply evidence and 4 have one. Research activity alone is not counted as supply.

Sources and method

Built from data the portal already publishes: the parts tree, the CORDIS projects and organisations, the published organisation pages, the post-quantum product records approved by an editor, the software directory, the funding rounds and deployment tracker files, the standards tracker, the technology areas, supply-chain segments and website product facts confirmed by editors, and a curated list of product lines named on European companies’ own product pages, each cited with a link and the date it was read. Restricted records are never used. A source without an identifier is linked to an organisation only when the names are identical once the legal form is removed. The type and SME status come from CORDIS, where the organisation declares them.

Assembled 2 November 2026 from 552 organisations; CORDIS snapshot of 2026-10-16; parts tree compiled 2026-10-25.
