Mr Green chief marketing officer Lahcene Merzoug is leaving the company to take up the role of managing director of ComeOn, a subsidiary of Swedish gaming operator Cherry AB.
Merzoug will join ComeOn by mid-July to replace Tomas Johansson, who has served as acting managing director of the iGaming brand since October 2017.
Merzoug joins Cherry from Mr Green, where he has served as CMO since February, having joined the operator following its acquisition of his previous employer, Evoke Gaming.
"ComeOn is a leading player with a number of well-known brands that inspire our industry, and I am honoured to take over as managing director after Tomas Johansson," Merzoug said of his new role. "I look forward to continuing to develop the operations to give the company a clear market-leading position and to strengthen our position as the first choice for customers and employees."
His predecessor, Johansson, serves as an adviser to Cherry and was brought in to lead ComeOn last year to reverse the brand's decline. His efforts appear to have been successful, with the operator crediting an improved performance from ComeOn as key to better-than-expected first quarter results.
"I'm pleased with what we have achieved within ComeOn in a short period of time, and it's very gratifying to see ComeOn return as a nimble player, focused on growth with good profitability," Johansson said. "Since October, we have worked hard within ComeOn to identify and remedy a number of different areas, allowing us to regain our position as a leading player in the industry."
Johansson will remain with the business as an adviser, assisting Merzoug and the rest of ComeOn's management team.
Commenting on the new appointment, Cherry chief executive and ComeOn chairman Anders Holmgren said: "Together with the rest of ComeOn's company management, Tomas has done a fantastic job of quickly reversing the trend within ComeOn, and the company now has more profitable and sustainable operations.
"Lahcene is the right person to take the company forward," he continued. "His experience of building growth in organizations and his well-documented marketing skills will give us a smooth transition and take ComeOn several steps ahead."
