The growing ranks of the super rich and their increased appetite for risk have caught the eye of investment bankers.

Traditionally focused on companies and institutions, investment banks are hiring staff and reorganizing teams to cater to wealthy clans, from Chinese multimillionaires to old world dynasties in Europe and the United States.

While some such families have been involved in direct investment for years, many more are just getting interested, seeing more potential for profit there than in funds or markets.
