Gustav Magnar Witzøe (born 1993 in Frøya) is a Norwegian billionaire and significant shareholder of salmon fish farming company Salmar ASA.[1] He is one of the youngest billionaires in the world.[2][3]

Early life[edit]

Witzøe was born in Frøya, Trondheim, to parents Gustav and Oddny Witzøe. His father founded SalMar, which is one of the world's largest producers of farmed salmon. SalMar also owns a significant stake in Scottish Sea Farms, the UK's second-largest salmon farmer.[2]

When he was 19 Witzøe served two weeks in prison after being arrested for driving 116 km/h in a 60 km/h zone.[4]


In 2013, Witzøe's father transferred 47% of the company to him to allegedly avoid a large inheritance tax bill.[5] Witzøe is involved with the family business and worked as a milker at SalMar's fish farms in Frøya.[2] As of December 2018, his net worth was $3.2 billion.

Witzøe is also a technology startup and property investor. He previously worked for MGM Property,[2] and has invested in both Gopi and Keybutler.[1][3]
