Texxi is a trademarked entity owned by a trust and licensed to various operating companies.
Much as any food or retail brand is legally distinct from the many operating instantiations, Texxi was designed to be separate from the various operating entities.
This was a necessary precaution to protect the early investors from “death spiral” tactics by larger, better funded competitors.
The brand can be found at the UK Patent and Trademark Office here -
The ownership of the 7 domains is documented with UK2.
