This week, new research has suggested that more young people than ever are starting their own businesses and a new entrepreneurial generation is growing. It got us thinking about how many companies will be started by youngsters who have barely left primary school - like these teenage entrepreneurs.
Remember the name Mallory Kievman, because this 13-year-old schoolgirl may just have created the next big high street remedy. In surely the medical/consumer breakthrough of the century, she's invented Hiccupops - lollipops that cure hiccups - and is currently working with MBA students from the University of Connecticut to bring them into U.S. stores. In a few years they could be sold worldwide, which shows just how far a simple idea can take you.
Fraser Docherty started making homemade jam with his grandmother at the age of 14 - but in just two years, he'd quit school in order to sell pots of organic preserve through his newly-created SuperJam company.
Now in his early 20s, Fraser's enjoying the fruits of his labour - as SuperJam is stocked in many of the UK's top supermarkets and he's selling 500,000 jars of it every year. Not bad for a hobby. Watch it here:
Most 9-year-olds want to play with toys rather than create a business - but not beauty product queen Leanna Archer. Inspired by her gran's homemade hair pomade, the American pre-teen started selling bottles of it to her friends before branching out into a whole range of natural oils, gels, skin care products and shampoos. These days, the 16-year-old is making more than $100,000 a year - which certainly beats the fast food jobs her friends are probably doing.
Setting up a technology company in your late teens seems almost passe these days - as many of today's multi-millionaires were founding companies from their college dorm rooms.
Seth Priebatsch, however, was doing it when he was just 12 - but instead of just programming from his bedroom, he was hiring people in Russia and India to code for him. Now 21, he's mobile app firm SCVNGR's "chief ninja" (so-called because you never negotiate with a ninja) and taking the tech world by storm.
If there's a young entrepreneur we've missed - or if you know what we should be thinking about next Friday - hit us up in the comments or on twitter. And let us know if you're sitting on a multi-million brainwave you had when you were a kid!
