Meta: Many Ask HN's annoy me to no end (like yesterday). Yours, however, does not (unlike smt88).

Personally, I don't think you will be able to build a business all by yourself, so I think it's in your best interest to think about the type of person (or people) you will need to generate a profit in your company's future.

For the people offering to help that you feel will not bring anything to the table, just say what you did here (i.e. "I'm a bit too obsessive about this project and feel it would hurt our relationship in the long-run."). Or, that your project is still too immature to add anyone at this point.

I wouldn't worry about such things at this point, just focus on launching and validating your project ASAP.
