@sellian are you naming your site for yourself or to attract your clientele?
Short, memorable, easily spellable, radio test and all that. But as a startup you want something inexpensive, preferably hand reg 'cos you can't get a lower price that that.
nommont.com? If you want French in there make it all French and think of that clientele. "Name mountain", nom mont. Not sure which way round that would go in French. montnom.com gives you "mountain name" as a palindrome but doesn't trip of the tongue quite so smoothly. Still sounds good to me though. Both are 7 letters, memorable, montnom probably easier to spell if heard rather than read. But of the two only nommont.com is available for hand reg. And it sounds a lot better than namemont.com or glorynames.com (OK for the younger set but your clients will be of all ages).
You are selling domain names, which in turn support brands of your clients at every visit to the sites they build on your names, plus with every email that goes out using that domain name as the address. They want to build those brands big. Mountain sized, in fact.
Also, a little bit different, refreshingly so. Look at the adverts on this site. Most contain domain, name or brand, or variants thereof. To the point it has become tedious (I've made the same mistake in naming my own business). So, name your mountain in French and use that domain as the brand to build your mountain sized business with.
