W4 Services Ag
W4 Services Ag is a Private limited company (Ltd.) registered in Switzerland under CHE110044583, and its current status with Zefix — Swiss Central Business Names Index is active. Its registered address on file is Baar, Switzerland. 1 shareholder is on record for W4 Services Ag, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Zefix — Swiss Central Business Names Index and was last updated on 9 October 2026.

Immediately above W4 Services Ag is W4 Holding AG, holding 100% as filed in W4 Services Ag's own shareholder record with Zefix — Swiss Central Business Names Index.
