Gen Z billionaires are here—and almost untraceable. Forbes has released a list of the 21 only billionaires under 30 years old, and the patterns are fascinating, as they are confusing. Most seem to be European and have extremely curated digital footprints. That is, none at all. But who are these enigmatic personifications of wealth? From self-made go-getters to trust fund semi-royalty, billionaires come in all shapes and sizes in 2025. These are the young billionaires of today, where their wealth comes from, and what we know about them.
Building Wealth Through Investment: The Andresen Way
Norwegian sisters Katharina, 29, and Alexandra Andresen, 28, are set for life, having been given a 42% stake in Ferd, their family's private investment firm, in 2007. Worth around £1.5 billion ($2.1 billion), Katharina is active within the firm, and is vocal about her passion for social entrepreneurship and LGBTQ+ rights, even serving as an Oslo Pride advisor. She boasts one of the most active social media accounts on this list—at least, one of the only ones.
Alexandra, a former junior dressage champion, is dedicated to horse breeding through Andresen Dressage. Although she became the youngest billionaire at age 19 in 2016, Alexandra insists she always used second-hand cars and was taught to save.
Born from the proceeds of a sold cigarette empire, the firm is run by their father, Jonah H. Andresen, who has 70% of the voting rights. Despite his generous donation, Andresen claims his daughters will not be forced into the company if they do not wish for a role in it. Though they are fairly low-profile, these sisters are still more vocal than most of the other entries on this list.
Keeping Business in the Family: The Del Vecchio Brothers
Across the Alps in Italy, three brothers—Leonardo, Luca and Clemente Del Vecchio skyrocketed in notoriety when they each became worth £4.85 billion ($6.6 billion) thanks to their inherited stakes in EssilorLuxottica. The world's largest eyewear company, the firm has spawned iconic brands like Ray-Ban and Persol. Each son inherited a 12.5% EssilorLuxottic stake after Leonardo Del Vecchio's death in 2022, as did their stepmother and six siblings.
Leonardo (Jr.), 29, named after his father, has a Bachelor of Business Administration from Bocconi University, and presently holds a more active role than his siblings, Luca, 23, and Clemente, 20. He serves as CEO and President of Ray-Ban and Salmoiraghi & Viganò, which EssilorLuxottica bought in 2016.
Leonardo is the son of Del Vecchio's second wife, while Luca and Clemente were born from his third marriage. They also have an older brother and two sisters from their father's first marriage. The Del Vecchio siblings' leap into wealth is similar to that of the Mistry brothers, who lost their father that same year.
Growth After Loss: Firoz and Zahan Mistry
Firoz Mistry, 28, and his 26-year-old brother Zahan Mistry inherited a 4.6% stake in Tata Sons, becoming billionaires after the tragic death of their father, Cyrus Mistry, in a car accident in 2022. Firoz is an alumnus of the University of Warwick, while Zahan graduated from Yale.
Tata Sons, which is based in Mumbai, is the holding company for the Tata Group. Its revenue is primarily generated through landholdings, tea estates, steel plants and brand loyalty fees. In 2025, the siblings successfully negotiated a refinancing deal worth £2.43 billion ($3.3 billion) for the company.
Now holding Irish citizenship, they also possess a 25% share in the Shapoorji Pallonji Group, a significant player in the construction industry.
Their journey, although marked by grief, is one of convenience compared to the stories of grit we hear from self-made entrepreneurs.
How Ed Craven Capitalised On the New Era Of Crypto
Ed Craven, an Australian-born entrepreneur aged 29, has amassed a £2.06 billion ($2.8 billion) fortune through Stake.com, the online crypto casino he co-founded. The platform exploded in popularity during the pandemic, driven by livestreamers and high-stakes digital gambling. Though banned in many jurisdictions, Stake reportedly accounts for 2% to 4% of all Bitcoin transactions. Presently, the platform delivers around £294 million ($400 million) daily profits, according to the Australian.
Craven founded Stake.com alongside his business partner, Bijan Tehrani. He claims that he was inspired by going into a casino at a family cruise when he was 12, and experiencing the dopamine hit of the lights and the victories. His business is driven by the same impulsivity that drove our next entry to drop out of university and pursue his start-up.
A Growing Tech Giant: Meet Alexandr Wang
On the tech front, Alexandr Wang, 28, shares Craven's youth-driven, billionaire status. Born in New Mexico to Chinese immigrant parents working at Los Alamos National Laboratory, Wang was a go-getter from the start. After dropping out of his mathematics and computer science course at MIT, he decided to pursue entrepreneurship full-time, claiming he would 'regret it' if he didn't take the risk.
His company, Scale AI, powers machine learning models for global giants like Meta and General Motors. Valued at £10.14 billion ($13.8 billion), Scale AI has earned Wang a personal net worth of £2.65 billion ($3.6 billion) as of April 2025, making him the world's youngest self-made billionaire.
While Wang had to network and market himself in order to secure sponsors and a client base, most billionaires on this list did quite the opposite, inheriting their wealth and remaining very, very quiet about it.
Quiet, Private Wealth, As Taught By Kevin David Lehmann
Kevin David Lehmann acquired his wealth at the incredible age of 14, when his father discreetly transferred a 50% ownership stake in dm-drogerie markt, Germany's top drugstore chain, to him in 2017. Despite owning half of the firm, neither Kevin nor his father is directly involved with the company's operations.
Kevin's father's investment in the company began in 1974, just a year after it was founded. Since then, the chain has expanded significantly, operating approximately 4,120 stores throughout Europe and generating over £10 billion ($14 billion) in annual revenue. dm started its journey in 1973 when Goetz Werner opened the first store in Karlsruhe, Germany. The following year, Guenther, Kevin's father, invested in the burgeoning brand while managing the family's Pfannkuch grocery business.
Kevin's lack of social media presence is only rivalled by the von Baumbach siblings, whose lives remain widely unknown.
The Secretive Boehringer Ingelheim Siblings
The family behind the pharmaceutical tycoon Boehringer Ingelheim is infamously wealthy and infamously low-profile. With a collective presence across 130 markets, their privately-owned pharmaceutical company is one of the largest in the world. However, not much is known about its heirs, Maximilian (27), Katharina (25), Franz (23), and Johannes von Baumbach (19), who each hold stakes that translate into a net worth of £3.97 billion ($5.4 billion). Despite their wealth, they're known for avoiding public appearances and having no visible digital footprint. All that is known is that Johannes is a competitive skier in Austria.
Their uncle has served as Chairman of the Board of Managing Directors since 2015, and has been an employee since 2001. None of the siblings is listed among the company's official leadership.
Similarly quiet to Von Baumbach is the next member of this list, whose tracks remain impressively untraceable.
Sophie Luise Fielmann, Eyewear Heiress
At 30, German billionaire Sophie Luise Fielmann is the co-heir to one of Europe's largest optical chains, Fielmann AG. Sophie and her brother Marc control most of the company, with him serving as CEO—starting at co-lead in 2018—and her being the majority shareholder, meaning she has 50% or more of its shares. Despite reportedly owning a third of the company and being worth £2.36 billion ($2.8 billion) because of it, she does not play an operational role in it.
The company was founded by her late father, Günther Fielmann, who passed away in 2023. Launched in 1972, Fielmann AG revolutionised affordable eyewear across Germany. With more than 1,000 locations and over 24,000 employees, the firm generated £1.69 billion (€2 billion) in revenue, solidifying its place at the forefront of European optometry.
The pattern of old European money continues on our next entry, this time with a German heir.
Chainsaws, Tools And the Family Business: Maxim Tebar
Maxim Tebar, 24, is the fourth generation to be born into the famous Stihl family fortune. Their company is best known for its chainsaws, but also makes trimmers, blowers and other forestry tools. Though much is not known about Maxim's role in the company, his mother serves as vice chair of the chain's advisory board. Founded by Maxim's great-grandfather, Andreas Stih, in 1926, the German company made £4.26 billion ($5.8 billion) in 2023. Though his exact cut is also unknown, Maxim is believed to be worth £809,031,735 ($1.1 billion). His net worth falls behind the next sisters on this list, whose gaming empire is only expected to grow.
Gaming Billionaires: the Kim Jung Duo
Sisters Kim Jung-min and Kim Jung-yuon came into wealth through loss, inheriting 9% ownership in Nexon, a South Korean-Japanese online gaming company, from their late father. The sisters are each worth around £956,156,545 ($1.3 billion), but, according to Forbes, they do not have a role in the company.
Nexon, which operates over 80 live games in more than 190 countries, is most well-known for its massively multiplayer online role-playing games (MMORPGs). Its portfolio also features popular titles such as MapleStory, KartRider, and Dungeon & Fighter. The Kim Jung sisters are as private as our final duo, and our only Latin American entry.
The De Assis' Sisters' Empire of Electric Motors
In Brazil, Lívia Voigt de Assis, 20, and her sister Dora, 27, are two of the largest individual shareholders of WEG, Latin America's primary manufacturer of electric motors. The sisters inherited a 3.1% stake each following the death of their grandfather, WEG co-founder Werner Ricardo Voigt. With annual revenues exceeding £4.9 billion ($6.7 billion), the company exports to over 135 countries.
Both sisters remain off the radar, with Lívia recently skyrocketing in popularity due to being named the world's youngest billionaire. Despite her newfound fame, Lívia has publicly expressed her desire to 'keep a low profile,' and is reportedly studying psychology.
The Gen Z billionaires of 2025 form a paradoxical bunch—extraordinarily wealthy, yet largely invisible. While a few have chosen public roles or entrepreneurial paths, most are heirs of vast, often European legacies, maintaining near-anonymous lives despite their immense fortunes. Amid the growing social media craze and the rise of the influencer, this new generation of billionaires is redefining visibility, power, and privilege in the digital age. Instead of dominating headlines, they are quietly shaping industries from behind private gates and minimal online presence. In a world obsessed with exposure, their silence makes for a sharp, jarring contrast.
