5. John Collison, 27 — $1 billion (£722.1 million).
Harvard dropout Collison co-founded Stripe, an online payment company, with his brother Patrick in 2011. The Irish-born brothers now live in San Francisco, where the company is based.
Stripe closed a $150 million funding round that valued the business at $9.2 billion in November 2016, according to Forbes.
4. Evan Spiegel, 27 — $4.1 billion (£3 billion).
Spiegel cofounded the popular photo-sharing app Snapchat with his former Stanford classmate and fraternity brother Bobby Murphy in 2011.
When Snap began trading in March 2017, he became the youngest public company CEO.
Spiegel and Bobby Murphy each own around 18% of Snap but have voting shares that give them control over the board.
Some 170 million people use Snapchat each day, according to Forbes.
3. Gustav Magnar Witzøe, 24 — $1.9 billion (£1.4 billion).

While his father runs the fish-farming business, Forbes reports that Gustav Magnar is focusing on making investments into real estate and tech startups.
