Its portable outdoor pizza ovens netted Ooni £10m in sales last year. Sold online and by retailers such as Selfridges and John Lewis, the ovens range in price from £199 to £499 and include the gas-powered Ooni Koda, which has a stone baking board, and the Ooni Pro, which can cook pizzas up to 16 inches wide. Chief executive Kristian Tapaninaho, 38, and chief experience officer Darina Garland, 38, set up the Edinburgh firm in 2012 and launched it through a Kickstarter campaign. It has seen considerable success on the platform, with its latest fundraiser, for the wood-fired Ooni Karu oven, raising almost £550,000. It has also attracted media attention for employing pizza taste testers, who develop recipes.
