Based on their logo it looks like: "one is to x"

On point - Its /wan-iz-tu-ex/ - referring to scale like 1:100, 1:500, 1:5 etc. In design, especially tangible design subjects like industrial design and architecture, everything is prototyped at some scale or proportions that is friendly to understand the design development.

If you have already considered this enough, disregard my comment..This name really trips me up as a german reader. If you like that it‘s a bit out there, that’s cool. If you want most people to read it like you just explained, you might need to capitalize the individual words.

Edit: just saw your logo. That reads well on first glance.

Looks like https://onetox.com/ is available. Maybe they can get big and buy it.
