It's not a matter of "convincing" people to try you out - it's a simple matter of memory. When you tell people your company name, they're going to do one of two things:
a) visit "YOURCOMPANYNAME.com"
b) Google your company name
Make it easier for people to hit your site 100% of the time by getting a .com.
