In his new role, Hellberg will spearhead PlayStar’s US expansion plans, with the brand due to launch in New Jersey before the end of the year and additional state roll-outs planned for next year.
Hellberg led Catena Media as chief executive from March 2018 to January this year, when he was replaced by Göran Blomberg.
Prior to this, he served as CEO and chairman of Readly, taking the business from start-up and putting it on the path to being listed on the NASDAQ Stockholm.
Hellberg also had a spell as CEO of Nordic Gaming Group (NordicBet), which was later acquired by Betsson Group.
“In PlayStar I see a challenger brand that has what it takes, both in terms of product and management team, to become a major player in the US market as it continues to roll out,” Hellberg said.
