Six young entrepreneurs from across Scotland will jet off an all-expenses-paid trip to California later this month after winning a Dragons' Den-style competition at Royal Bank of Scotland's global headquarters in Edinburgh.

The winning entrepreneurs will attend the Global Start-up Summit in San Francisco before taking part in a week-long programme of events in Silicon Valley, including meetings with executives from Apple, Ebay and Hewlett-Packard as well as various start-up companies.

The winners are: Calum Leslie, founder of Wooju; Ola Clark of Monomise; Ian LeBruce of Cappuccino Ads; Craig Lynn of Filament PD; Sonny Charles of Spoilty and Ross McNairn of Dorsai.

Before leaving for the United States, the young entrepreneurs will attend team-building and leadership sessions with creative leadership trainer Ilana Wetzler and take part in a strategy session with Skyscanner's chief financial officer, Shane Corstorphine.

Leslie, 23, from Edinburgh, took the tech world by storm when he launched his app, Wooju, in April. In the three months since its launch it has been downloaded by more than 24,000 users in 54 countries and for a time became the sixth-most downloaded app on the iTunes App store.

The free-to-download app describes itself as "a simple way to snap and solve indecisive moments with friends". It means young women out shopping who want a second opinion on buying a dress can send a photo of themselves trying it on to friends who are then instantly polled about whether or not she should buy it.

It could also be used to help someone decide whether to buy an attractive stranger at a bar a drink, or whether to drink the slightly-off milk in the fridge.

Leslie said he had been taken aback about the app's success.

The trip to California later this month will be an opportunity to drum up further business for his Glasgow-based companies which had previously launched two other apps. The company, which launched last year, now has five full-time employees.
