Tesco buy up Glasgow Kevin Harvie's gluten free Hectares crisps The year was 2013, and 27-year-old Kevin Harvie was slicing his way into an entrepreneurial dream. Frustrated by the distinct lack of sweet potato crisps in his work vending machine, Kevin was determined to make his mark on the world of snacks. "I had no experience in crisps, but when you get an idea in your head you just have to run with it," he said. Kevin, now nicknamed 'Crisp Boy' had already swapped his regular white potatoes for sweet potatoes in his evening curries as he loved their healthy nutrients. Convinced other people would like this gluten free sweet potato crisps too, he started cooking and dishing up his own snacks for friends in a variety of flavours. "I kept practicing in my kitchen and people seemed to like them," said Kevin, a former Dundee University graduate. I packed in my job as an accountant to make crisps and just ran with it. I just thought - I'm going to be the guy who makes sweet potato crisps. A year on, and Southside born Kevin has just signed a nationwide deal with supermarket Tesco, with him now set to make a comfortable turnover of £150,000 by the end of the year. Hectares Sweet Potato Crisps have hit the shelves, and Kevin is keeping a close eye on his precious packets on display. "The best thing is seeing your idea on a shelf," he said. It's a bit embarrassing, but I've been in there down the aisles, straightening up the packets to make them look good - I just can't help it. The entrepreneurial streak has already shone among young Scots like Kevin. In 2007, Alloa teenager Fraser Doherty hit the headlines after signing a deal to supply his jam to a supermarket chain. He began with his grandmother's recipe which he adapted to blueberries and cranberries, known as super fruits, using natural juice as a sweetener instead of sugar. One year later and SuperJam hit around £1 million in sales. "You have to sell a lot of crisps to become a millionaire though," said Kevin with a laugh. We've achieved a wee bit but not that much. We've got a lot planned over the next six months too. At the moment it just feels like the start of the journey for us.
