The winners, unveiled at a ceremony in Glasgow last night, include Mhairi MacLeod, owner of digital marketing agency Lux, who won the award for best visionary business.
Lux specialises in food and drink, with clients including BrewDog, Montpelier (Edinburgh), Highland Fayre, Cuckoo's Bakery, Thistly Cross Cider and Roots.
Ms MacLeod was one of two Edinburgh winners on the night as Hamish Lawson, owner of DaDa Underwear, lifted the award for best e-commerce operation. Mr Lawson set up DaDa after spotting a gap in the market for comfortable and stylish male underwear.
The Edinburgh winners were joined on the podium by Ross Baynham of Argyll-based Harrison and Fyfe, an online male accessories store (best website), and Frazer Reid of FAR Cabinet Makers in Fife (most environmentally responsible business).
The awards were set up to recognise young entrepreneurs who have benefited from BT Scotland funding and have grown their business with the help of a website or online platform.
Allan Watt, director of The Prince's Trust Scotland, said: "The Prince's Trust helps over 600 young Scottish entrepreneurs start up each year. Tonight's winners are great examples of the success our young business owners can have and the contribution their success makes to their local communities."
Liz Turner, head of corporate responsibility at BT Scotland, said it had been "another stellar" year for the awards programme.
