RUBIX LIMITED
RUBIX LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 10485684, and its current status with Companies House is active. The company was incorporated on 18 November 2016 and lists its registered address as London, United Kingdom. 4 shareholders are on record for RUBIX LIMITED, 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 Companies House and was last updated on 1 October 2026.

Data availability
Those 2 subsidiaries span United Kingdom, Norway jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Two of the 2 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
