The Silicon Valley tech boom has led to the rise of the so-called "Hollywood angels," as musicians, actors, and athletes look to score big by becoming startup investors.

Some of these celebrities have already proved their business acumen: Hollywood actor Ashton Kutcher is famous for his early bets on companies like Uber, Airbnb, and Spotify, while Jay-Z, Katy Perry, and Serena Williams famously joined forces to invest in meat-replacement startup Impossible Foods, now valued in the billions of dollars.

Business Insider took a look at the actors, musicians and sports stars who are most actively-involved in the US tech funding scene, using data from Crunchbase.

While it's not always clear how much cash each individual celebrity has sunk into startups, given that they're usually participating in much larger funding rounds, we do know how often they've had their names attached to a deal. We've ranked these celebs by the number of funding events they've participated in.

We've also drawn a distinction, where possible, between personal investments by a celebrity and those made by a VC firm or fund with which they're associated. In some cases, the different is minimal: Serena Williams is the sole founder and principal of her fund, Serena Ventures. But others, like U2 frontman Bono, are only part-owners of the fund, and have limited participation, making the distinction an important one.
