We started doing business in the web hosting industry to bring innovative new features to VPS hosting. Lots of Virtuozzo/OpenVZ hosts out there, probably because it's very cheap to maintain.
After working with Virtuozzo, KVM, Hyper-V, and Xen, I found that I really liked Xen for how realistically its virtual machines act like dedicated servers. Xen can even virtualize within a virtual machine.
To create a company name, I had someone else try to come up with a name, but he only made some variation of "Texan" (we're incorporated in Texas), like "ATXXEN", which reads "Austin Texen"
The only name I could come up with was "Xenfinity", which doesn't have any special meanings except being a portmanteau of "Xen" and "Infinity", and since I didn't like any other name candidates that popped up, "Xenfinity" stuck.
