Kevin David Lehmann Net Worth and 3 Other Billionaire Gen Zers: Inside Their Family Fortunes

The wealth gap between generations has never been more apparent. While most Gen Z individuals are still navigating their first jobs and student loans, a select few have already accumulated billion-dollar fortunes—though not through traditional entrepreneurship. According to Forbes’ latest billionaires list, every billionaire under 30 inherited their wealth rather than building it from scratch. Among them, Kevin David Lehmann stands out as one of the most striking success stories of inherited fortune, alongside three other exceptional cases that reveal how family business empires create generational wealth.

Kevin David Lehmann: From Teen Billionaire to $3.3 Billion Net Worth

Kevin David Lehmann became a billionaire at just 14 years old, making him one of the youngest people to ever achieve this status. His father gifted him a 50% stake in dm-drogerie markt, Germany’s leading drugstore brand, when he was barely into his teenage years. Today, in his mid-twenties, Kevin David Lehmann’s net worth has grown to over $3.3 billion, though he maintains a low profile and remains operationally detached from day-to-day business operations.

The foundation of Kevin David Lehmann’s wealth traces back to his grandfather, Gerhard Lehmann, who made a shrewd investment in 1933 by acquiring a 50% stake in the Pfannkuch Group. This decision, made nearly a century ago, proved to be one of the most lucrative moves in retail history. The investment eventually transformed into a 50% ownership share of dm, which evolved into a massive drugstore powerhouse worth billions. The Lehmann family’s consistent strategy of remaining low-profile while building enduring retail institutions has been key to their longevity and wealth preservation.

Clemente Del Vecchio: Ray-Ban’s $4.7 Billion Fortune

At 19 years old, Clemente Del Vecchio inherited one of the world’s most recognizable brand portfolios when his father received a substantial stake following his grandfather Leonardo Del Vecchio’s death in 2022. Leonardo Del Vecchio, an Italian businessman and founder of Luxottica, built an eyeglasses and optical retail empire that dominated global markets.

Leonardo’s journey began modestly in 1967 when he started selling individual parts for eyeglass frame assembly. By 1971, he shifted to selling fully assembled frames, and the business snowballed into unprecedented success. At the time of his death, Leonardo Del Vecchio had amassed a personal fortune exceeding $24 billion, making him one of Italy’s wealthiest individuals. His youngest of six children, Clemente Del Vecchio, inherited a $4.7 billion stake in Ray-Ban and other luxury optical brands under the EssilorLuxottica umbrella, instantly making him one of the world’s youngest multibillionaires.

Zahan Mistry and the $4.9 Billion Tata Group Legacy

Zahan Mistry, now in his late twenties, received an inheritance worth nearly $5 billion following the 2022 death of his father Cyrus Mistry, who was deeply connected to India’s most powerful business conglomerate: the Tata Group. Cyrus Mistry himself was the heir to Indian construction billionaire Pallonji Mistry, meaning wealth had already been consolidated across generations.

The Mistry family’s connection to Tata Group—a diversified holding company with interests spanning steel, automotive, information technology, and hospitality—provided Zahan with exposure to one of Asia’s most dynamic business ecosystems. Both Cyrus and Pallonji held substantial equity stakes in Tata Group, each worth over $20 billion at their peaks. When the inheritance passed to the next generation, Zahan Mistry’s net worth jumped to approximately $4.9 billion, positioning him as one of the wealthiest young individuals globally.

Remi Dassault: Aerospace Dynasty Worth $2.5 Billion

French billionaire Remi Dassault inherited his $2.5 billion fortune under tragic circumstances in 2021 when his father died in a helicopter crash at age 69. Unlike the retail and conglomerate backgrounds of the other young billionaires, the Dassault family built their empire in aerospace and defense—a sector with deeper historical roots.

The Dassault fortune originated when Remi’s grandfather invented an airplane propeller for French military aircraft used during World War I. This innovation led to the founding of Dassault Aviation, which became France’s most prominent aerospace manufacturer. Today, Remi Dassault controls stakes in both Dassault Aviation and Dassault Systèmes, a leading global software and digital transformation company. His combined holdings, valued at approximately $2.5 billion, represent one of the most technically advanced wealth portfolios among Gen Z billionaires.

The Inheritance Pattern: Understanding How Billionaire Gen Zers Built Their Net Worth

The common thread connecting Clemente Del Vecchio, Zahan Mistry, Kevin David Lehmann, and Remi Dassault reveals a fundamental truth: billionaire Gen Zers didn’t build their fortunes through startups, innovation, or market disruption. Instead, their net worth stems from inheriting controlling stakes in multigenerational family businesses established by entrepreneurial ancestors.

The timeframes are telling. Leonardo Del Vecchio started with eyeglass components in 1967; Gerhard Lehmann secured his retail investment in 1933; the Dassault family roots go back to World War I aviation innovation. These weren’t overnight successes but carefully cultivated business empires spanning 50 to 100+ years. Each generation refined operations, expanded markets, and consolidated wealth, creating compounding effects that transformed initial investments into multibillion-dollar legacies.

What distinguishes these young billionaires from their peers isn’t entrepreneurial genius or market timing—it’s access to pre-existing wealth infrastructure. Their net worth figures reflect the accumulated value of family enterprises rather than personal financial achievements, a distinction that matters when evaluating true business acumen versus inherited advantage.
