The World’s Youngest Billionaires in 2025: Who They Are and What They’re Doing Now
The billionaire ranks of 2025 include a new generation of ultra-wealthy individuals under 30 — a mix of heirs to global empires and a select few self-made innovators. According to Forbes and The Indian Express, there are just over 20 billionaires worldwide aged 30 or younger. While most inherited their fortunes through family dynasties, a handful are carving out paths in tech, AI, and crypto that redefine what “self-made” means today.
Below are the 10 youngest billionaires of 2025, how they made (or inherited) their money, and what they’re doing now to shape their futures.
1. Johannes von Baumbach (19) – Heir, Boehringer Ingelheim
At just 19, Johannes von Baumbach stands among the youngest billionaires on the planet. He inherited part of the Baumbach family’s stake in Boehringer Ingelheim, one of the world’s largest pharmaceutical firms, known for developing medications for diabetes, respiratory diseases, and cardiovascular health.
In 2025, Johannes is reportedly continuing his education while engaging in family philanthropy and corporate legacy projects. He plays a symbolic role in the company’s future governance, with his wealth tied to the enduring success of the multibillion-dollar family enterprise.
2. Clemente Del Vecchio (20) – Heir, EssilorLuxottica & Delfin Holdings
Clemente Del Vecchio, the son of the late Leonardo Del Vecchio, founder of Luxottica, inherited a significant stake in Delfin Holdings, the family’s investment arm controlling EssilorLuxottica, the eyewear giant behind brands like Ray-Ban and Oakley.
Now 20, Clemente is involved in next-generation leadership discussions at the family level. While not yet publicly active in business operations, his role focuses on stewarding investments and ensuring the family’s presence in Europe’s luxury and fashion sectors. His fortune symbolizes the enduring strength of old-world family capitalism meeting modern global luxury.
3. Lívia Voigt de Assis (20) – Heir, WEG Industries (Brazil)
Lívia Voigt de Assis is Brazil’s youngest billionaire and one of Latin America’s youngest female billionaires. She owes her wealth to her family’s stake in WEG Industries, a powerhouse in electric motors and automation technology.
In 2025, Lívia continues to expand her influence through family-led foundations that focus on education and sustainability in Brazil. She represents a new wave of South American wealth that blends corporate inheritance with social impact initiatives.
4. Kim Jung-youn (21) – Heir, NXC / Nexon (South Korea)
Kim Jung-youn inherited part of her late father Kim Jung-ju’s fortune, the visionary founder of NXC Corporation, which controls gaming giant Nexon, known for titles like MapleStory and Dungeon Fighter Online.
Now 21, Kim holds her wealth through family trusts but is expected to become more publicly active in the tech and gaming investment space. In 2025, she continues to represent a quiet but powerful presence among South Korea’s new generation of tech billionaires, with her family’s empire expanding into blockchain-based gaming and digital entertainment.
5. Kevin David Lehmann (22) – Heir, dm-drogerie markt (Germany)
At 22, Kevin David Lehmann remains one of the youngest billionaires in Europe. His wealth comes from a 50% stake in dm-drogerie markt, Germany’s leading retail drugstore chain founded by his father.
Unlike many heirs, Lehmann has maintained an extremely private life. In 2025, reports indicate he is pursuing private investment and family office ventures focused on sustainability and retail innovation. His fortune, estimated at over $2 billion, is tied to the continued dominance of dm-drogerie markt in Europe’s consumer goods market.
6. Luca Del Vecchio (23) – Heir, EssilorLuxottica & Delfin Holdings
Another of Leonardo Del Vecchio’s heirs, Luca Del Vecchio, shares in the vast wealth generated by EssilorLuxottica. Like his brother Clemente, Luca is being groomed for future involvement in the family’s sprawling fashion and optics empire.
In 2025, Luca has been seen attending luxury brand events and taking part in educational programs linked to international business and finance. His presence in the European elite underscores how the Del Vecchio heirs represent the continuity of one of the world’s most iconic luxury dynasties.
7. Franz von Baumbach (23) – Heir, Boehringer Ingelheim
Franz von Baumbach, Johannes’s older sibling, is another beneficiary of the Boehringer Ingelheim fortune. Alongside his younger brother, Franz has inherited substantial shares in the global pharmaceutical company.
As of 2025, Franz is involved in philanthropic projects related to medical research and education, aligning closely with Boehringer Ingelheim’s global mission to innovate in healthcare. The von Baumbach family maintains a low public profile, focusing instead on multigenerational stability and responsible business stewardship.
8. Rémi Dassault (24) – Heir, Dassault Group (France)
Rémi Dassault hails from the legendary Dassault family, which built fortunes through aviation, software, and media. The Dassault Group, known for its Mirage and Rafale jets and its stakes in Le Figaro, continues to anchor one of France’s most powerful dynasties.
In 2025, Rémi is reported to be pursuing business and financial studies while taking part in the family’s investment initiatives. As the aerospace and defense industries boom, his inheritance continues to appreciate, cementing his status as one of Europe’s youngest industrial heirs.
9. Maximilian Stihl (25) – Heir, Stihl Group (Germany)
Maximilian Stihl is part of the founding family behind Stihl, the German manufacturing giant famous for chainsaws and outdoor power tools. The company remains family-owned and globally dominant.
In 2025, Maximilian plays a role in the family’s governance and corporate modernization strategy, including sustainability-focused innovation. He is also active in Europe’s growing “green tech” investment space, aligning traditional industry with future-focused innovation.
10. Alexandr Wang (28) – Self-Made, Scale AI (United States)
Breaking the pattern of inherited wealth, Alexandr Wang is one of the few self-made billionaires under 30 in 2025. The son of immigrant physicists, Wang co-founded Scale AI, a company that supplies training data for artificial intelligence and machine learning systems.
In 2025, Wang made headlines after Meta acquired a large stake in Scale AI, making it one of the most valuable AI companies in the world. Following the deal, Wang joined Meta in a senior leadership role focused on AI innovation. His entrepreneurial journey — from MIT dropout to billionaire tech leader — makes him one of the standout stories of self-made success in an age of inherited wealth.
Conclusion: What It Really Takes to Become a Billionaire Before 30
The 2025 list of the world’s youngest billionaires underscores a stark truth: most are heirs, not self-made moguls. The Del Vecchios, von Baumbachs, and Dassaults represent legacies built over generations, now transferring vast fortunes to the next wave of wealthy heirs.
However, self-made billionaires like Alexandr Wang and Ed Craven prove that in the age of AI, blockchain, and digital enterprise, it’s still possible to build a billion-dollar empire from scratch. They stand as proof that innovation, risk-taking, and technological foresight can rival even the most established family dynasties.
In 2025, the divide between inherited and self-created wealth has never been clearer. Yet whether by birthright or breakthrough, each of these billionaires symbolizes the evolving face of global wealth — one defined by entrepreneurship, data-driven innovation, and generational transformation.
