Hi. I'm Aaron Weinman. Behind the fortunes of wealthy folks like Google cofounder Sergey Brin, or the Hyatt hotel heirs JB and Tony Pritzker, are some of the most qualified women in banking and finance.

Brin's family office, Bayshore Global, named 35-year-old Goldman Sachs alum Marie Young as chief investment officer in January. Mousse Partners, the family office for the heirs to the Chanel fortune, are managed by Suzi Kwon Cohen, who previously led private-equity investments at Singaporean sovereign wealth fund GIC.

Nearly 90% of the world's billionaires might be men, but when it comes to managing their money, it seems they look no further than the women plying their trade at investment banks, investment firms, and hedge funds.

Insider talked to female family-office employees about why women thrive as CIOs for secretive, wealthy families.

1. Rich people, many of whom are men, trust women to manage their billions. According to research, women tend to skew conservative in investing when the market sentiment is bad — which is ideal for the family offices of billionaires, which love a long-term outlook on investment decisions. 

In addition to Sergey Brin and the family office that manages the $90 billion Chanel fortune, there is also the Walton family and the founder of hedge fund Renaissance Technologies, Jim Simons, who have appointed women to manage their finances.

In fact, 20% of family offices around the world have a woman as chief investment officer or a senior investment specialist with titles like private equity or senior asset manager, according to a 2021 survey from trade publication Family Capital and Guernsey Finance.

Why this is the case is difficult to pinpoint. But from a broad strokes perspective, many chalk it up to a longer-term mentality that is sometimes difficult to find in the cutthroat, quick return-on-investment strategies prevalent on Wall Street, among other factors.

"A lot of men do great, but there is a small section that aren't as collaborative and don't get along as well with families, whereas a lot of women are able to navigate the family office dynamics," according to Wendy Craft, who runs the family office of real-estate heir Kent Swig.

Insider's Hayley Cuccinello has the story on why so many women help billionaires manage their mountains of money.

Hayley has also previously outlined 21 people, from advisors to lawyers, who are powering the monster growth in family offices.
