More than one quarter of the wealthiest family business dynasties in the world are linked to other dynasties through formal business associations like directorships on each others companies, underlining the power of family wealth in the 21st century. Family Capital has analysed the board of directors and supervisory boards of 500 of the biggest family businesses in the world in terms of revenues and found that at least one in four had a director on their board that had come from another family business dynasty. The link becomes even stronger when Family Capital looked at the number of non-family directors who had worked in a senior position for another family business before joining the board. Although this is more of an informal relationship, it is fair to assume that these individuals keep links with their former employer, i.e. the family, which are no doubt useful to the new employer and family owners.
