Like many women her age, Kylie Jenner is active on social media. But she’s done one thing that no one else has: build a billion-dollar fortune by age 21.
Jenner is the youngest person to become a billionaire with her own company, Kylie Cosmetics, and she has several other young billionaires to thank.
“The business would not exist at its current size without social media,” said Conor Begley, co-founder of brand-marketing company Tribe Dynamics.
Instagram co-founder Kevin Systrom, Snapchat co-founder Evan Spiegel, Facebook co-founder Mark Zuckerberg and Twitter co-founder Jack Dorsey are all billionaires younger than 45.
