From what's been previously mentioned in this thread, we know that Clay has had a warehouse in Florida printing/embroidering merch designs and pressing those goofy challenger coins since September of 2020. We've known this much for over a year now, and honestly it's not that difficult to get something like this set up when you're raking in millions from tweens.
We also know that this warehouse has been printing the merch for Sapnap and George since the first half of 2021, with BBH signing onto it earlier this year.
According to the WhoIs link you posted, the domain was originally purchased last year, with it going live sometime in
early June according to the Wayback machine. Sure, anyone can register a domain or open an Aktiebolag, LLC, or Corporation, but I did a bit more digging to see where else the Paradime name was popping up. Besides Skeppy's site, here's a few shops I found using Paradime for fulfillment.
DreamSMP merch shops tied to Paradime
Other merch shops tied to Paradime
Most of these sites were found digging through archives of the Paradime.media site, as well as looking at what sites
ChillAndBeReal worked on. Given several of these shops seem to have been active since summer of last year, it looks like the company has been working with a decent amount of creators since it was started.
