From textiles to petroleum
Engineer Arne Sandberg got his very first job at Saab before he started textile company 'Stålnylon' (Eng. translation: Steel Nylon), which specialised in overalls and . After a few years at that firm, it was actually a late payment of an invoice that first introduced Arne to what later became his life's work: petrol. Instead of getting paid, Sandberg was offered the chance to set up a Swedish branch of a small Norwegian petroleum company.
So, that is the story of why Arne founded Uno-X in Sweden in 1960 and set out to compete with the Swedish petrol monopoly. The established petrol companies later accused Arne of having poor-quality petrol, but the motorists loved him, and with very clever marketing, his two petrol stations quickly multiplied to 300.
Let's do something fun instead!
In 1967, when Arne turned 50, he sold petrol company Burmah Castrol for 30 million SEK. According to Arne's wife Maja, he supposedly blurted out: "Let's do something fun instead of buying shares", and that bit of fun turned into their project Billingen Hill.
