Jared Leto -- actor/musician
Investments: Frame.io, Nom, Headspace, Blue Bottle Coffee, Zenefits, PlateJoy, Life On Air Inc., Reserve, Reddit, Superpedestrian, Radius, Robinhood, Surf Air, Gobbler
As if moonlighting as a rockstar weren't enough to keep this Oscar winner busy, he's amassed an impressive investment portfolio with stakes in 14 different companies -- including Surf Air, a members-only, on-demand private jet service that only flies around California.
Jessica Alba -- actress/entrepreneur
Investments: Headspace, Managed by Q, Honor
You may have heard about Alba's own billion-dollar venture, The Honest Company, which she co-founded in 2011, but she's also a financial backer of a few others including Managed By Q, which is basically a TaskRabbit for office managers. Unclear whether James Bond is involved.
