Partnerships are tough, especially when all want to be active. Someone has the be the chief, and the rest indians. Cannot run a tribe with 2-3-5 chiefs.
As far a building a team, you need a good point guard, and dominate center....
Actually you can build a good team from scratch overtime without partnerships. InterCosmos is a great example. While 5 partners own business, only 1 runs day to day operations. Yet we have 63 employees who make one hell of a team.
