TEMPO.CO, Jakarta - The vast world is home to countless billionaires. While the title is often associated with CEOs or founders of global companies over the age of 30, a rare few achieve billionaire status in their 20s—earning the title of the youngest billionaire in the world.
Unlike most who spend years—or even a lifetime—building a financial empire, many of these young billionaires inherited their wealth through family businesses.
Who Is the Youngest Billionaire in the World?
As of April 2025, Forbes has named 19-year-old Johannes von Baumbach from Germany as the youngest billionaire in the world. Sharing the reputation, the top 10 young and wealthy individuals include:
1. Johannes von Baumbach (19 years old - $5.4 Billion)
Johannes von Baumbach is noted as the youngest billionaire in the world, with an estimated net worth at $5.4 billion. He, and his other three siblings, inherited the German pharmaceutical company Boehringer Ingelheim founded by Albert Boehringer in 1885.
2. Lívia Voigt de Assis (20 years old - $1.2 Billion)
As noted by Forbes, Lívia Voigt is one of the largest individual shareholders of WEG, the largest manufacturer of electrical motors established by her grandfather, Werner Ricardo Voigt. With an impressive net worth of $1.2 billion, Lívia is not involved in any executive role or board seat, instead focusing on her university studies.
3. Clemente Del Vecchio (20 years old - $6.6 Billion)
One of the six children of Leonardo Del Vecchio, Clemente inherited a 12.5% stake in Delfin after his father’s passing in 2022. The Luxembourg-based holding company owns a significant stake in EssilorLuxottica—the world’s largest eyewear firm, founded by Leonardo himself. As of April 2025, Clemente has an estimated net worth of $6.6 billion.
4. Kim Jung-youn (21 years old - $1.3 Billion)
Kim Jung-young, alongside her sister, is another youngest billionaire in the world, valued just over $1 billion. Her father, Kim Jung-ju, founded the online gaming giant Nexon in 1994. Following his passing in 2022, the sisters each inherited a 9% stake in NXC, the holding company that remains the largest shareholder in Nexon.
5. Kevin David Lehmann (22 years old - $3.6 Billion)
Kevin David Lehmann’s astonishing net worth of $3.6 billion stems from a quiet transfer of a 50% stake in Germany’s leading drugstore chain, dm (drogerie markt), made by his father in 2017.
The investment—made just a year after dm was founded—proved to be highly lucrative, with the chain now operating over 3,700 locations. Both Kevin and his father maintain a low public profile and have no known involvement in the company’s operations.
6. Franz von Baumbach (23 years old - $5.4 Billion)
The 23-year-old Franz von Baumbach ranks just five places behind his brother Johannes on the list. With a net worth of $5.4 billion, his wealth also comes from Boehringer Ingelheim, a pharmaceutical giant employing 53,000 people. Even so, the extent of Franz and his siblings' involvement in the company remains unknown.
7. Kim Jung-min (23 years old - $1.3 Billion)
Kim Jung-min is the older sister of Jung-youn, and she also holds a 9% ownership stake in NXC. Little is publicly known about the sisters, and neither is involved in the operations of Nexon.
8. Luca Del Vecchio (23 years old - $6.6 Billion)
Similarly as Clemente, Luca Del Vecchio is also a herit of 12.5% stake of Delfin. The holding company not only owns significant shares in EssilorLuxottica, but also UniCredit and Generali. Luca and Clemente are the only two children of Leonardo Del Vecchio and Sabina Grossi, Luxottica’s former head of investor relations.
9. Remi Dassault (23 years old - $2.8 Billion)
As of 2025, Rémi Dassault holds an estimated net worth of $2.8 billion. Much of his fortune comes from Dassault Aviation, the French aerospace giant founded by his grandfather. The Dassault family is also known for owning the prominent newspaper Le Figaro and a private aeronautics company.
10. Maxim Tebar (24 years old - $1.1 Billion)
Stihl is one of the world’s most well-known chainsaw manufacturers, and Maxim Tebar stands as the fourth generation to inherit it with a net worth of $1.1 billion. Founded in 1926, the company saw $5.8 billion in sales in 2023, according to Forbes.
Some of the world’s youngest billionaires are living proof that financial success comes in many forms—this time, through family legacy. If this inspires you to explore further, take a look at the richest men in the world.
