Mansour will join Buzz later this month having previously served as chief executive of Bragg Gaming, where he had been serving as chief executive before leaving the business last year.
Prior to this, Mansour had a spell as senior vice president for South Europe at PokerStars and also as managing director at Full Tilt.
“We operate in a highly competitive, fast-moving sector but one in which Buzz’s omni-channel opportunity gives something unique,” Mansour said.
“I know after more than 20 years in this industry, all over the world, we have the ingredients to really succeed and grow. I’m really looking forward to bringing my experience to Buzz and to work together to drive the business onto the next stage.”
Buzz Bingo chief executive Chris Matthews added: “Dominic coming on board with his exceptional sector and leadership experience will be crucial in driving the next phase of digital growth for Buzz.”
Meanwhile, Buzz Bingo has also appointed Shaves, currently its chief digital officer, as its new chief commercial officer.
Replacing Jamie Queen, who is set to leave Buzz at the end of January, Shaves will head up bingo, slots and food and beverage product development, as well as partnerships, procurement and driving Buzz’s omni-channel strategy.
“Stevie has done an incredible job taking Buzzbingo.com from an idea to one of the UK’s leading online brands in just over two years,” Matthews said. “I am excited about what Stevie can deliver for us in his new commercial group role.
“I’d also like to thank Jamie for his hard work and considerable achievements and wish him luck in his new ventures.”
The double appointment comes after Buzz Bingo in October last year also named Harry Lang, the founder of marketing consultancy Brand Architects, as its new marketing director.
