Our firm has named a number of companies. In my experience, these are tough projects, as it's difficult to determine which is objective/subjective feedback.

Some of our most successful names were ones that clients hated initially, but later found very usable. Although some are put-off by names that feel different at the outset, once they are spoken a few times these ones often become more memorable.

I like undrln because it’s short, and there’s a bit of a tongue-in-cheek nod to the tools we use every day in it. Seems to be working: http://search.twitter.com/search?q=undrln
