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
The commercial Swiss counterpart to ECMWF's public AIFS: a private physics foundation model (EPT-2) sold as a weather API to energy traders and utilities, with a REST API exposing 25+ models and Apache Arrow support. Pricing is per simulation run, an unusual unit worth recording — $0.20-15 per run versus €1,000-20,000 for classical NWP.
