> 100% of the top 20 YC companies by valuation have the .com of their name. 94% of the top 50 do. But only 66% of companies in the current batch have the .com of their name. Which suggests there are lessons ahead for most of the rest, one way or another.
To me it suggests that having high valuations may be the cause of having the .com domain. A more useful analysis would be when companies that are now successful got their domains.
I will let the YC mavens give their opinion on YC, but in other cases in business coming into something with 'here is our name or concept but by all means if you want to change it let me know' is not seen as a good sign of commitment to your own creativy.
That doesn't mean you name your company and stay with it 'till the bitter end'. But it also doesn't mean that you name your company and then open it up to a vote by others as to what you should do (and not be decisive with your own convictions either).
