I am working on an app with some friends / family. We've all put in some money, split up what our ideal shares would be (i.e. 70/20/10), and after launching our app we're starting to gain some traction. We would like to become a legal corporation to protect us, and at the same time we need to do what is best for the startup. How the heck do I figure this out?
Talk to a corporate attorney who specializes in startups. Setting up a <i>real</i> startup (assuming that's what you want) is a lot more involved than merely setting up a corporation.
