Description: There is a growing interest in the phenomenon of family offices. These organizations are privately owned, often providing services such as account aggregation or concierge, and are thought of managing a sum of $6 trillion around the world. Their strategic agility and their care in maintaining secrecy over their activities makes them not just very influential long-term investors, but also severely understudied. By developing a systematic literature review from academic and practitioners’ sources, the objective of this thesis is to provide a deep overview of what we already know about family offices, and to offer new research directions to understand better this fascinating organizational phenomenon.
