Family businesses are all about family, relationships and the dynamics that result. The two schools of thought around this are either that you already know all there is to know about each other so know how to work together successfully, or that family and business when it comes to siblings is a recipe for disaster.
This article provides a good insight into the former, how siblings can work together and build successful businesses that hopefully can stand the test of time.
A lot of us view the concept of “sibling partnership” as sharing the last cookie in the cookie jar instead of fighting over it. But these siblings are taking it a step further -- by starting companies with each other. In the entrepreneurial community, some say sibling partnerships are stronger than any other kind, because siblings have known each other their whole lives. Others advise avoiding sibling partnerships at all costs, otherwise there's no good way to separate business from family.
