Should Co-founder Be Given Equity?

A lot of startup companies are better off with two people on board.  After all, the name "Company" literally means "more than one person".  When someone invite another person to be a cofounder, what are the points of discussions associated with equity share?

Here are a couple of major points to consider.

(1) Does the cofounder pay cash into the company coffer?
(2) Does the cofounder need to quit current job and forego salary?
(3) Does the cofounder need to take a pay cut from current level or industry standard?
(4) Should the cofounder be given private equity?

Keep in mind that a cofounder is important.  The founder is a status, a position, and a responsibility.  These three goes together.  The status means it is obviously a later badge of honor.  But the cofounder has to earn it with what he/she does for the company.  A cofounder should be a builder in chief - building the product, the sales channel, or something critical.

Later when the team goes to ask for funding from an investor, the investor WILL ASK this question "are both you working full time for the company".  It is important to keep this in mind.  If when you go to investor and one of you have not given up your job, it just looks bad.

A cofounder is not a high level employee.  A cofounder is a founder. 

Cofounder is not a gig.
