Evidence boundaries
Organisation listings identify a reviewed canonical record. 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
The European-founded company that scaled fastest into frontier-lab territory — Anthropic's build partner, USD 830M Series A — and the clearest example of a European compute startup relocating its centre of gravity to the United States. For a European directory it is a cautionary data point on the 'European stack' thesis rather than a usable European endpoint: no published prices, no confirmed EU datacentres, and a New York headquarters.
