Randi Zuckerberg has seen giant wealth firsthand and has a strong opinion on how money is best spent.

Zuckerberg has been outspoken about the need for workers — particularly women — in science, technology, engineering and math occupations.

"I spent a lot of time being the only woman in the room, so I have a personal drive and passion to make sure that this tech skills gap applies to women and girls in a meaningful way," she said, in an earlier interview with CNBC.
