Is starting a company where I am not nor have ever been a customer or recipient of put me at an automatic or nearly insurmountable disadvantage?
Dude what if I told you that the people who run big tobacco companies don't smoke? Or that the people who give out payday loans never get payday loans? Or that the founder of Taco Bell (possibly) never ate an actual taco and he definitely wasn't Mexican. I highly doubt Christian Louboutin wears high heels either.
As long as people want to pay for your service then this is no big deal at all!!
