Headquarters evidence

14 renowned European research and computing centers have joined forces to develop an open European infrastructure for web search.

The project's own site describes OpenWebSearch.eu as an EU-funded project in which 14 European research and computing centres have joined forces; it is a distributed Horizon Europe consortium rather than an entity with a headquarters. No headquarters wording exists anywhere on the site.

Evidence boundaries

Organisation listings identify a reviewed canonical record. Headquarters is independent of incorporation, registered offices, ownership, hosting and runtime. Model listings show an association in the source register; they do not by themselves establish model creation, current API availability, hosting location or infrastructure ownership.

Profile note

Europe's attempt at an independent web index — the infrastructure prerequisite for both a non-US search engine and a non-Common-Crawl pretraining corpus. Five founding data centres (CERN, LRZ, IT4Innovations, DLR, CSC) plus nine research institutions. The OWI was in beta as the original grant ended 28 Feb 2026; continuity now depends on the successor project SOURCE and on the Open Search Foundation. This is the most under-funded strategically-important item in this file: €8.5M against a task that Google spends billions on annually.
