You should have a clear agreement among all founders.

The agreement should cover at least two main issues:

1. Roles and responsibilities.

You should define the role and expectations of each founder. First, define who does what and titles; Second, define who holds final authority within different aspects of the business.

2. Equity ownership and vesting.

You need to allocate the ownership of your new enterprise among the founders. Even split isn’t always the right choice. You may have tell your co-founders they are not your co-equal. But it’s always better to have that conversation on day one and not to move forward with a new enterprise and then get stuck on who owns what.
