I think when it comes to names and naming (a subject I’m temporarily expert on) there are only two things you really need to know: (1) Pick names with few syllables. The number of syllables matters more than the number of letters. Proof? Apparently, and you can bet your house on this, easily pronounced stocks do better on the stockmarket. (2) Don’t expect analytical feedback. If research shows that people are more likely to buy things if they share letters in common (e.g. Matt, Marmite) then you can’t expect people to give you anything but idiosyncratic feedback on the name you picked.
