I can imagine a developed site on the first name.........in Dutch
I don't know if these are brandable, but they are unregistered:
They all sound kinda weird, but the thing about branding is that this doesn't necessarily have to matter so long as it's short enough and can be easily pronounced and remembered. It's a matter of associating it with a great product/service and/or with a great message. Some that I like slightly more than the others: Xeqon, Kojix, Nocoy, Mozib.
Might also be a good idea to see if any real words can be related to these names. For example, Nocoy has a word "coy" in it and "No Coy" could refer to "no pretense, just honest information" or something like that. It could also be something "uncensored", like uncensored jokes or people posting uncensored opinions about things or other people..
The names really have to roll off of your tongue easily if they are going to be memorable.
A lot of 5-letter brands that started out as nonsense words have done well. Xerox, Kodak, Exxon...
