Depending on the size of your market, it's possible that the TLD won't matter so much in the beginning. At that point you may be more reliant on word-of-mouth and early adopters, so a non-traditional TLD could be in your benefit, giving you time to prove out the idea and generate some income that can be put towards purchasing the .com version.
