How to name a startup?

Alright, thanks everyone. That cellar door trick is interesting! I think I will keep it to three syllables or less and I want to go with a .com domain so that the general public won't get confused or anything like that. I see the ly and .io things as just fads and I want my business to be around for awhile so I will just stick with what is traditional. Also, it is interesting that so many of the best startups in the last 15 years have been two syllables...Google, Facebook, Twitter, Uber, Yahoo, etc.

I have found it difficult to come up with a good domain name so far, because it seems like so many have been taken.

I do not remember where exactly I have heard this, maybe from my friend who created his startup couple of years ago. Anyways - the name may bring more attention if it contains three syllables with emphasis on the last one and if it sounds similar to this nonsense phrase: 'sellerdoor'

Add ly to the end of whatever it is your product does.

Just kidding, I hated that trend.

Nah not really. Just make sure to use no vowels and get a .io domain.
