Lívia Voigt de Assis: The World’s Youngest Female Billionaire of 2025

Lívia Voigt de Assis, 20, is worth $1.1 billion and ranks 2,888 on Forbes’ list, making her the World’s Youngest Female Billionaire of 2025. She inherited a 0.09% stake in WEG, Latin America’s leading electrical-motor manufacturer, which her grandfather, Werner Ricardo Voigt, co-founded in 1961 alongside industrialists Eggon João da Silva and Geraldo Werninghaus.

Though WEG operates factories in more than ten countries and generated approximately $6.7 billion in revenue in 2024, Lívia has no executive role or board seat. Instead, she divides her time between attending university in Florianópolis, Brazil, and stewarding her shares quietly.

Her older sister, 26-year-old Dora Voigt de Assis, also appears on Forbes’ youngest-billionaire roster after earning an architecture degree in 2020. Together, the sisters represent a new generation of wealth rooted in Brazil’s industrial sector rather than in tech startups or real estate.

At just twenty, Lívia faces choices that could shape WEG’s future and her own career path. Industry observers note that many heirs first complete higher education before taking on corporate responsibilities, a path Lívia seems poised to follow.

Regardless of whether she eventually joins WEG’s leadership or pursues a different direction, her meteoric rise underscores the enduring power of family-founded manufacturing champions in creating lasting fortunes.

What’s Next for a Young Heiress?

At just twenty, Lívia faces choices that could define her long-term role in WEG’s future. Will she take an active management path, or continue her academic pursuits before deciding whether to join the family enterprise? Analysts note that many heirs delay corporate roles until they gain experience or further education. Lívia’s current focus on university suggests she may follow a similar route.

Regardless of her next steps, Lívia Voigt de Assis stands out as a symbol of how family-founded industrial champions can spark fresh success stories. Her position reminds us that even in an age of tech unicorns, legacy manufacturing businesses still produce some of the world’s youngest and most enduring fortunes.
