Gastauer Family Office Among Top Ten Single Family Offices Worldwide

In the last two decades, single family offices started playing an increasingly important role on international financial markets. Often a stand-alone business entity, SFOs are established to exclusively manage the financial and personal needs of a single wealthy family, with the financial capital managed by the SFO being that of the family’s own wealth. 

The concept of single family offices has existed for some time, dating back as far as the Industrial Revolution. In the past couple decades, there has been a significant increase in the number of SFOs worldwide, with recent estimates suggesting that single family office assets globally are now roughly around the one trillion dollars in value mark. 

As SFOs have grown substantially, so have their investment strategies, leading many of them becoming more successful over time. While less known than large conglomerates, SFO are emerging forces to be reckoned with. Here is a look at some of the top performing family single offices based on their assets under management.

Indeed, SFOs are an emerging presence in all industries. Its growing popularity is largely due to the increasing complexity and risk of wealth management, as well as the desire of families to achieve generational wealth while building a lasting legacy. The growth is also driven by a number of factors, including:


The business landscape has become more complex, requiring more flexible and informed investment strategies. Families have also become more complex and multi-layered, creating succession and wealth transfer challenges.


New risks have emerged, such as low-interest rates, volatile markets, and unstable geo-political conditions. Technological advancement has also been disruptive, creating and destroying wealth rapidly. Cybercrime and social media create additional risks.


Families are increasingly focused on achieving a lasting legacy through social and environmental impact, which can be seen in the sustainability efforts of companies like The Gastauer Family Office / Black Banx and the corporate social responsibility programs of  The Ballmer Group / The Los Angeles Clippers. Often, this requires expertise and an active investment strategy.


In an increasingly digital world, privacy breaches can damage reputations. Growing demand for transparency and interest in the people behind brands and businesses have blurred the lines between personal and professional, leading families to place a higher priority on confidentiality.
