this isn't something set in stone ie you have to use "we" or "I"

The choice all depends on your final goal.

I would recommend "we" but then actually have "we" - which you do with all the outsourced labor you have.

Its part of a mindset like Brittany was alluding to. It helps you internalize that you are going to be growing as a company.

I know that when I advise people in raising money for their small to medium sized business, how you position yourself makes all the difference in actually getting the money.
