Make a list of every word that you feel is associated with what you do, or that invoke a feeling you want associated with your brand. Some of them can be things like "rocket" or "super". Make the list long and then just start stringing two of the phrases together to see which ones sound good. My digital music startup ended up being called "Earbits" (ear = music, bits = digital). I recommend staying away from things that are spelled incorrectly or that will require clarification when you tell people the name. Make sure the .com is available, although you can get away with other domains if you plan to have a strong SEO strategy. You can also do names that have nothing to do with what you do, like made up words, but again, if you have to explain how to spell it, you're fighting an uphill battle.
