I have an ongoing bet with Keith Kaplan that any company named ___ster will fail. I loved Napster and their founders. They really did change the world. These other “sters” are sad.

Even companies with original ideas add the “ster” suffix. Why?

My advice is to start with the primary meaning you want your name/brand to have and find domains that are available/affordable. Namespinners at Buydomains can certainly help. If you are really stuck you can hire a naming company like A Hundred Monkeys
