Build Your Team
Will you add to your team in-house? Or will you outsource to others?
For example, if you do not have the technical skills to build your product, you'll either want:
a) a technical co-founder who will put in a lot of time in exchange for little pay but future equity
b) a company you can hire to do the technical build, but they will likely charge you more up front, be less collaborative, and you'll have to be more specific up front with what you want.
If you add a co-founder, you'll want to think about how you share equity. Foundrs.com has some great questions to consider.
