While it’s good manners to sit down and debate each decision, come to a conclusion that satisfies everyone, and each member having an opportunity to put in their opinion. The business can’t run like that. Not a small business. Larger ones can, but they don’t really want to expend the “meeting tax” if they can avoid it.

Someone (ONE person) should be the CEO, with well defined roles/responsibilities for the strategy and direction of the company.

If you take on the CEO role, it’s YOUR company. You should have the most at risk, You should be the first to blame, YOU are the representation of the company.
Therefore, you should have a larger share of the company, in compensation for the additional risk.

Everyone is equal, everyone gets a portion proportional to the risk/value/talent they bring. But ONE person has to be able to finalize the decision, make a decision in absence of any consultation, and it is his neck on the line.
Play nice, be friends, but understand that making crucial decisions for the business is not something to be done by comittee.
