You might have to change the company name in the future, because you will also need to find a matching domain name (an address on the internet like google.com). Good and short domain names are very hard to register, so there's a good chance you will have to switch your startup name to something else in the future. However, this isn't a bad thing. Google wanted to be called Googol, but they couldn't get that domain name, so they "settled" with Google.
How Google became Googol
If you want to check to see if your domain is available, head over to GoDaddy.com and check it out. Don't be in a hurry to register a name, because the name you have chosen might not necessarily be ideal for your product - in the future sections you will be tweaking yor solution, which might help you think of a better company name.
Don't worry though. The name doesn't make the company, the company makes the name.
