I would also tend to shy away from 4 equal leaders.

ONE PERSON, whether a member of the 4 or not (preferably not), needs to have the go/no-go authority. That person would give a go/no-go based on consensus of the 4 in normal situations, keep the 4 accountable to each other and to the rest of the team, and break any ties in the 4 leaders.

This person will also need to be good at easing disputes by mediation, keeping focus on the goal (and anything else that needs doing on the team like fundraising), and encouraging the team through tough times. Not an easy job. That's why I'm saying the 4 probably shouldn't be equal in the whole leadership of the team.

Think of it this way. There is the President of the United States, and the Cabinet. The Cabinet advises the President on what he could/should do--but the President has to make the choice.

So, this is why I'm suggesting one person to be the go/no-go person (and team captain or whatever you want to call him/her), over the 4. This raises a point of, what if the G/NG person isn't there? Well, they can name a proxy if they aren't there for a decision and know they won't be, or you can go to the 4, with choice going either by seniority on the team or age from oldest to youngest, or you can have whoever's department is most responsible for the decision make the final call. That's something to handle within the team.
