Both Holloway and Jossel will serve as independent members of the board, with the double addition taking the total directors on Super Group’s board to nine.
Holloway joins the Super Group board following the merger with special purpose acquisition business Sports Entertainment Acquisition Corp. (SEAC), where she was chair of the board’s audit committee.
Prior to this, she served in various roles for the National Football League across nearly two decades, including most recently as vice-president of business operations and strategy.
Jossel is currently chief executive of the Plaza Hotel & Casino and has nearly a decade of gaming industry experience, having served in the role since 2014.
As chief executive, Jossel played a key part in the Plaza’s expansion during the revitalisation of the downtown district of Las Vegas.
“We are thrilled to welcome Jonathan and Natara to the Super Group board,” Super Group chief executive Neal Menashe said. “They both bring a wealth of experience relevant to our industry and will be able to provide valuable perspectives as we continue to pursue our global growth strategy.”
Super Group completed its merger with SEAC in January, having entered into a definitive agreement last April, based on a $4.75bn (£3.89bn/€4.52bn) pre-money equity valuation.
