Phase 1 seed dataset, compiled by hand. These rows were built from public operator, laboratory and vendor sources. A mechanical second-reader pass has since fetched every cited source: 1263 of 1345 systems have a readable citation that names them, and 56 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

What this machine is made of

One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.

The read

Pure Data Centres Group's AI data center campus on 370 acres in Seinajoki, Finland: a 110 MW first phase (1.5 billion euros, fully leased to hyperscale and technology customers, direct liquid cooling in repeatable 40 MW modules, first substation already live) designed to scale beyond 550 MW at over 7.5 billion euros, with over 700 MVA of renewable electricity available. Pure DC closed 1.3 billion euros of senior debt for phase one in July 2026 (SMBC, ABN AMRO, Citi, Societe Generale, Natixis). The tenants are not named in either page and no GPU type is stated, so the tier is reported.
