Hey
@Rothex,
I had a quick look at both your keywords (Calorie and Whisperer) in namebio, and neither one appears to be particularly popular in the aftermarket.
I also had a look on Google, and the term itself doesn't seem to be in use anywhere.
From a strictly subjective standpoint, as a brandable name, I don't think it's very intuitive. By that I mean that I'm not sure the two words really belong together. The popularity of the "whisperer" term came from (I think) the Horse Whisperer novel and movie, and so the word really needs to be paired with a living creature to make any sense. Check out this definition from Dictionary.com:
"Whisperer - a person skilled in taming or training a specified kind of animal, typically using body language and gentle vocal encouragement rather than physical contact."
For this reason mainly, I think you'll have a difficult time finding a buyer for the name. Brandable names are so hit-or-miss already, but especially when they don't have clear, existing end users. So if you're going to invest in one that doesn't have any existing end users, the two words really need to have excellent synergy (borrowing a term from
@Keith DeBoer there) to be worthy purchases.
Unfortunately I'll have to give this one a reg. fee valuation, but I would still put it up on the big marketplaces with a low XXX BIN and see what happens before renewal time comes around.
I do like a couple of the names on your portfolio site, so keep plugging away! You're on the right track with Specialty/Movers.
