Who are the world’s youngest billionaires?

When most of us think back to our late teens and early twenties, becoming a millionaire, let alone a billionaire, is not one of the milestones we recall from that time. However, the same won’t be said for these individuals when they look back in years to come.

Kevin David Lehmann, 18

Incredibly, German billionaire Kevin David Lehmann is just 18 years old, but is worth an astonishing £2.6bn. His father, Guenther Lehmann, is the owner of German drugstore chain drogerie markt and transferred a 50% stake of the company to Kevin when he was 14. However, this remained under a trusteeship until he turned 18 in September 2020 and officially became the world’s youngest billionaire!

Austin Russell, 26

At age 26 and with a net worth of £1.37bn, Austin Russell is doing ‘pretty’ well for himself, despite dropping out of Stanford University in 2012. Although, his reason for dropping out was because he received $100,000 from the Thiel Fellowship, a private foundation funded by billionaire Peter Thiel, co-founder of PayPal and an early investor in Facebook. The money from the fellowship was so Russell, now the world’s youngest self-made billionaire, could start Luminar Technologies, a company that makes sensors and other tech for autonomous vehicles, and he has since gone on to amass his fortune.

Andy Fang and Stanley Tang, both 28

Chinese-American Andy Fang and Hongkonger Stanley Tang are billionaire tech entrepreneurs worth £1.73bn and £1.58bn respectively. They cofounded food delivery app DoorDash back in 2013, and unlike many businesses that floundered under the effects of the pandemic, their business became more valuable than ever as ordering food online became more commonplace. Currently, DoorDash is the largest food delivery company in the US, with a 5% market share and nearly 4,000 employees.

Johnny Boufarhat, 26

In May 2021, Johnny Bouharfat became the UK’s youngest billionaire, with a net worth of £1.5bn. The creator of video conferencing app Hopin, Bouharfat first came up with the idea in his girlfriend’s bedroom back in 2018, after being bedridden with a mystery illness.

Amazingly, the app now has more than five million users and is valued at £4.1bn.
