Today is entrepreneur-friendly; even those who are far from 18 years old can jump into the business wave. Some of them have achieved tremendous success and are making money we can\’t even imagine. Many of them started their businesses in elementary school. Here are six of the most interesting child billionaires.

Isabella Barrett
Now a 13-year-old girl, she became a millionaire at an age when it is common in our country to be in first grade. She was at first a child miss and star of a youth television show. She made her fortune primarily through her cosmetics and jewelry brand, Glitzy Girl, and became a millionaire at the age of nine.

Cameron Johnson
This enterprising young man made his first money at age 9. At the request of his parents, he made invitations to neighborhood festivals, which were a huge success with the people. In his first two years, he earned over $100,000; at age 13, he expanded his business to selling stuffed animals. Today he speaks and writes books about his business. [age 18] [age 19] [age 20] [age 21] Madison Robinson [age 22] [age 23] You may be surprised to learn that even the lack of nice flip flops in the store can be a catalyst for entrepreneurship. Madison, who was 8 years old at the time, eventually made her own summer shoes. Not only were they well received by her classmates, but they were sold in local stores. And so was born Fish Flops, a brand that sold over $20 million in its first two years alone.

Nick Darozio
Born in 1995, the young Englishman had been interested in computers since childhood; by age 15 he had mastered coding and created his own app, Trimit, which could simplify news articles. He was able to improve this app with funding from Japanese investors. He then sold his newly created Summly for $30 million.

Mikayla Ulmer
made a fortune selling lemonade made from a family recipe. Bee Sweet Lemonade, as the name suggests, was sweetened with honey. She signed an $11 million contract with the Whole Foods chain when she was only 11 years old. [age 34] [age 35] [age 36] Fraser Dougherty [age 37] [age 38] By using a recipe that had been handed down from generation to generation, she was successful in this case as well. This time, however, it was marmalade. He started making it when he was 14 and sold it in his neighborhood; two years later he refined the recipe and super jam was born. It soon filled store shelves all over England.
