Jönsson, who will start in his new role on January 10, will succeed Billy Degerfeldt. Scout confirmed last month that Degerfeldt would be taking up the same position with another undisclosed business after serving a notice period.
Jönsson arrives at Scout after having garnered extensive experience in the sector.
He spent more than a decade as an accountant with PwC before spells with Global Gaming Group and Evolution Gaming in Malta.
“It will be fun to utilise my existing knowledge from the sector, even though Scout is completely unique in terms of its product offering, and I am convinced that I will be able to contribute from day one,” Jönsson said.
Scout chief executive Andreas Ternström added: “It feels very good to be able to present Niklas, who has many years of experience in the industry and knows what it takes to accelerate growth.”
Earlier this month, Scout launched daily fantasy sports platform Fanteam in the US.
Last month, Scout confirmed that its quarterly revenue dropped by 19% year-on-year between July and September.
However, Ternström said at the time that the company had “worked intensively to launch our tier-one clients” over the three-month period.
“These tier-one clients will generate growth during the 2022 and beyond,” he said, adding that lower marketing expenses over the quarter had led to improved earnings in comparison with the previous year.
