12 globe's richest youngsters 2015.

There are 1,826 billionaires on the recent Forbes list. Out of this, 46 are still under the age of 40 and about half of them made their fortune in the tech industry. But it's the youngest of the young moneymakers who make for the most interesting reading.

According to Forbes, three new billionaires have managed to achieve their ten-figure status before cracking the age of 30: Snapchat co-founders Evan Spiegel (24) and Bobby Murphy (26) join beer heir and DJ Julio Mario Santo Domingo, 29, on the global richlist.

Snapchat CEO Evan Spiegel is officially the world’s youngest billionaire - not bad for someone who's made his fortune off an ephemeral photo messaging app.

After meeting co-founder Murphy at Stanford University and suffering through their flopped first photo app together, the significantly more successful Snapchat app is now used by 100 million people every month.



Facebook CEO Mark Zuckerberg 30-year-old, made his own fresh-faced debut at the of age 23. He is now the 16th richest person in the world, reportedly worth $33.4-billion. Among some of the other self-made new additions are Uber's Travis Kalanick, and Airbnb duo Nathan Blecharczyk and Brian Chesky. Joining them is blood test developer Elizabeth Holmes, one of nine women on the young billionaires list, and at 31, the youngest self-made woman in the world.

Evan Spiegel, Age: 24, Net worth: $1.5-billion

Evan Spiegel is the CEO of Snapchat, the temporary photo messaging company he co-founded with Bobby Murphy in 2011. The company, which was valued at $10-billion in 2014, was reported in February to have received offers to nearly double that valuation to $19-billion. In December, Spiegel earned rave reviews from tech peers and press for his business acumen after some emails written by the young CEO were made public in the fallout from a major hack of Sony Entertainment. After growing up comfortably in the Los Angeles area, Spiegel studied product design at Stanford University and met Murphy at the Kappa Sigma frat house, who was two years ahead of him and studying math.

After meeting Spiegel at Stanford's Kappa Sigma frat house, the two eventually developed an app that could send photo messages to contacts with a timer that would remove them in 10 seconds or less and called it Picaboo - and it flopped. Rebranded as Snapchat, the app took off in the fall of 2011 and is now used by more than 100 million people monthly, for free.
