7 young billionaires are all richer than Kylie Jenner

Even if Jenner had stayed on the list, a 19-year-old drugstore scion would have passed her as the youngest billionaire in the world.

Here are the seven youngest billionaires in the world, from Oslo, Norway, to Orlando, Florida.

Gustav Magnar Witzøe, 29

Worth: $4.2 billion

Gustav Magnar Witze, a Norwegian model, has been given good looks and $4.2 billion.

His father, who was also named Gustav, started one of the biggest salmon farms in the world, Salmar ASA, in 1991. In 2002, he gave his share of the business to his only child, who was also named Gustav. The model became a billionaire when he was 18. He now lives in an Oslo penthouse with his Staffordshire bull terrier, Aro, and a view of the Aker Brygge waterfront.

Witze told The Telegraph, "The day after I got the stake, I wasn't any better off or worse off." Still, it's my dad's business, and he makes that choice. It's mostly paper work. It's not like the money goes to your bank account right away."

Still, the 29-year-old lives in style, driving around in a Lamborghini Urus that costs $160,000.

Witze doesn't have to work, but he keeps himself busy with three jobs: modeling, investing in start-ups through a company he co-runs called Wiski Capital, and running his charitable The W Initiative, which gives money to groups that help kids' health and education.

After high school, he even worked on the salmon farm for two years.

“It was a really great experience, it’s so nice to work outside all day, using your body. You get home and you’re exhausted. I learnt a lot about the industry and how things worked,” he told The Telegraph.

Ryan Breslow, 28

Worth: $2 billion

Ryan Breslow dropped out of college, like a few of the other billionaires on this list. He left Stanford to work on Bolt, the payment startup he started his sophomore year. The software lets online retailers accept payments with just one click. This makes doing business so much easier for e-commerce companies that Bolt is now worth $11 billion. Breslow has a huge net worth of $2 billion.

Breslow is one of the world's youngest billionaires, but his three-bedroom home on the edge of Miami's Little Haiti neighborhood, not far from where he grew up in North Miami Beach, doesn't exactly make him feel like a billionaire.

During Breslow's childhood, his two grandfathers worked together to run a denim shop, an accounting firm, and a seafood market. His parents also ran a golf range in the area. Breslow's family has always been business-minded, but he doesn't make a big deal about his success, especially on Instagram, where he only posts about work.

Forbes says that Breslow spends most of his time alone at home. On the AstroTurf in his back yard, he dances to "house disco" music. He thinks while palm trees, white statues of Buddha, and a humming air conditioner are all around him. And he runs Bolt from a treadmill desk in his sunroom, near the ritual drums. In the same article, Breslow, who eats vegan food, said, "I live like a monk." He stays away from gluten, booze, and caffeine.

"Most rich people want to be part of an exclusive group. Breslow, who only uses candlelight after dark so as not to mess up his sleep cycle, has said, "I don't want anything to do with it." He is likely one of the only billionaires who feels this way.

At the beginning of 2022, he made his 800 Bolt employees work only four days a week. He said, "There's too much work theater, where people go through the motions to look busy. I'd rather you spend your time off taking care of your health, well-being, and family, so that when you're at work, you're all in."

Pedro Franceschi and Henrique Dubugras, both 26

Worth: $1.5 billion each

Henrique Dubugras and Pedro Franceschi, two Brazilians who started coding when they were young and are now worth $1.5 billion each, made Forbes' list in January 2022, five years after they co-founded the fintech startup Brex. Their company changed the way small businesses spend money by letting startups use corporate credit cards, which is something most young businesses can't do.

When Dubugras was in high school in Sao Paulo and Franceschi was in Rio de Janeiro, they met. In an interview with The Takeoff in 2020, Dubugras said, "We met at the end of 2012 while arguing on Twitter about Vim vs. Emacs, two programming text editors... Fighting over 140 characters got hard, so we went to Skype and became best friends there."

Dubugras didn't just fight with Franceschi, though. Dubugras said in the same interview, "I was fighting with my mom, moved out of my house, became an adult, and ran out of money." Instead of getting a job to make money, he and two other coder friends, but not Franceschi, went to Miami to compete in a hackathon competition with a $50,000 prize and won.

Dubugras says that Franceschi "started coding when he was nine, and when he was 12, he became a very famous hacker because he was the first person in the world to jailbreak the iPhone 3G."

Dubugras and Franceschi were both accepted to Stanford University in 2016, but they left after only eight months to work full-time on Brex, whose headquarters are now in San Francisco. At the start of the pandemic, the dynamic duo and Franceschi's wife moved to Los Angeles. 

In 2018, Dubugras told Nasdaq, “People warn against doing business with family and friends, but I wouldn’t be where I am today without Pedro by my side and I know he’d say the same.”

Alexandra Andresen, 26, and Katharina Andresen, 27

Worth: $1.2 billion each

Each of these Norwegian sisters was given 42% of Ferd, an investment company that their father, Johan H. Andresen, started in 2001. Today, each of these shares is worth $1.2 billion.

The Independent says that even when she was a teen equestrian, Alexandra didn't just spend her billions on anything. "I save when I get my weekly allowance, when I win money in a contest, or when I get money as a birthday present. It means I don't have to ask my parents for money to buy things I really want, like a bag or a pair of shoes," she said in 2016.

Before Forbes put them on the list for the first time that year, Alexandra was 19 and Katharina was 20, both studying social sciences at Amsterdam University College. Before that, they lived quiet lives in Oslo. Still, Alexandra was known as the three-time Norwegian junior dressage champion.

Katharina paid a $32,000 fine in 2017 for driving drunk at a Norwegian ski resort. In July, she graduated from Regent's University London, where she studied global management. She used Instagram to celebrate her graduation by posting a picture of her and her dad.

The Andresens share their passions with their thousands of Instagram followers, which is different from some of the other billionaires on this list who keep their personal lives private. Alexandra's feed is full of pictures of her with her many horses, and every now and then, the red-headed heiress posts a cute picture with her boyfriend, 28-year-old Colin Thompson, a former racecar driver and founder of the Paramount Wood Co. furniture brand.

Katharina also has a boyfriend, a Norwegian businessman named Frederic Kvasnes who is 32 years old. They have posted photos from Paris, Santorini, and Rome that they took together.

Austin Russell, 27

Worth: $1 billion

Austin Russell became the youngest self-made billionaire in 2020, when he was 25 years old. He was the founder and CEO of Luminar Technologies, which makes software for self-driving cars. His company, which is based in Orlando, Florida, went public that same year. His wealth is now $1 billion.

"College is not the right place to be able to see through a technology, a vision of a product, or anything else," Russell, who dropped out of Stanford after his first year, told Forbes. "The incentive and reward is to get a paper published, not to be able to see something truly meaningful through to the world at large and to be able to see that far ahead. I was able to do all of those things because I dropped out of school."

Another thing that helped was winning $100,000 from the prestigious Thiel Fellowship, which was started by PayPal co-founder and fellow billionaire Peter Thiel to help young entrepreneurs get their businesses off the ground. 

Russell became a billionaire at the end of 2020. He then spent $83 million on a mansion with six bedrooms and 18 bathrooms in the Pacific Palisades neighborhood of Los Angeles, about an hour north of where he grew up in Newport Beach. Two months later, he bought a $10 million home in Winter Park, Florida. He probably did this so he could be closer to the headquarters of his company.

Some people don't like him or what he made, though.

In an interview with CNBC in 2019, Elon Musk said that Russell's lidar technology was "freaking stupid," "expensive," and "not needed."

Russell replied, "I don't think 50 business partners and most of the big automakers we work with would agree."
