Alphabet (the company formerly known as Google) and Apple may be the most valuable tech companies these days, while Microsoft has the richest founder in Bill Gates (also the world’s richest man).

But no one has spun off more billionaires than Facebook. The company founded in a Harvard dorm room by Mark Zuckerberg and a cadre of fellow techies has been part of the 9-figure success stories of 8 people, according to the latest Forbes Billionaires list.

That’s more than Alphabet, which placed 6 on the list, or Microsoft with four, or Apple, which counts only Laurene Powell Jobs. It’s certainly more than Twitter, with only Evan Williams and Jack Dorsey on this year’s list. In fact, Facebook, which just celebrated its 12th birthday last month, has more billionaires floating around than any other tech company.

So who has Facebook made obscenely wealthy? How rich are they? And what did they do for the company?

Mark Zuckerberg

What he’s worth: $44.6 billion

Facebook’s CEO and co-founder is pretty much synonymous with the company he started in his Harvard dorm room and grew into a social media behemoth with a market cap of $310 billion as of today and more than 1 billion users. His Facebook fortune means has made him the sixth richest man in the world.

Dustin Moskovitz

What he’s worth: $8.9 billion

Moscovitz co-founded Facebook and was the company’s first chief technology officer, later becoming its vice president of engineering. He left the company in 2008 to cofound team tracking software company Asana with Justin Rosenstein.

Jan Koum

What he’s worth: $8.6 billion

The cofounder of WhatsApp was catapulted into the billionaire ranks when Zuckerberg bought his company for $22 billion.

Eduardo Saverin

What he’s worth: $6.2 billion

Saverin co-founded Facebook and managed the business side in the early days while Zuckerberg worked on the product. In 2005, Zuckerberg ousted Saverin and diluted his ownership in the company. But after suits and countersuits, Saverin owns about 5 percent of the company, worth a pretty penny. Shortly before Facebook’s IPO, Saverin renounced his U.S. citizenship and now works in Singapore, mainly as an angel investor.

Brian Acton

What he’s worth: $4.4 billion

Zuckerberg’s decision to beef up Facebook’s messaging capabilities paid off for this WhatsApp co-founder as well.

Sean Parker

What he’s worth: $2.4 billion.

The co-founder of Napster was Facebook’s founding president, and worked to bring VC Peter Thiel aboard as Facebook’s first institutional investor while preserving Zuckerberg’s power over the company’s direction. Even after leaving Facebook, Parker remained involved as an advisor to Zuckerberg.

Jeff Rothschild

What he’s worth: $1.8 billion.

In 2005, Rothschild, now 61, became the oldest person at Facebook, where he’s vice president of infrastructure.

Sheryl Sandberg

What she’s worth: $1.2 billion.

Facebook’s COO, Sandberg is one of the most powerful women in tech and played an essential role in the company’s growth.
