Aberdeen social enterprise Glencraft and whisky firm BenRiach won honours for Scotland at the 2015 Private Business Awards (PBAs) in London.
Glencraft, which makes mattresses and bedroom furniture, was lauded for its approach to hiring and skills development.
The firm, now based in Lang Stracht, was named social enterprise of the year after recently notching up £1.35million in annual sales and achieving its five-year ambition of relocating to a long-term site in the city.
It has also secured a prestigious contract to supply the new Serco Caledonian sleeper trains.
BenRiach, the Edinburgh-based firm behind the BenRiach, GlenDronach and Glenglassaugh single malt whiskies, won the high growth business of the year category of the PBAs.
The awards are run annually by professional services giant PwC. Other Scottish finalists in the latest edition included Ellon-based BrewDog, Banchory firm Ecosse Subsea Systems and Renfrewshire company Peak Scientific Holdings.
Martin Cowie, head of private business at PwC in Scotland, said: “To have five Scottish companies make the final was a remarkable achievement, and for two to win their categories says much about the resilience of the economy.
“Our finalists and winners are great examples of how tenacity, innovation and a strong market focus can help create highly competitive, successful businesses in their respective markets.”
