De Souza served most recently the global head of strategy and operations with BGO Entertainment.
Before his four year spell with BGO, de Souza spent eight years with Betway group overseeing its retention department.
MrQ.com operator Lindar Media managing director Savvas Fellas said: “Dan has amazing exposure and understanding of both the operational side and of the commercial side of what it takes to run a successful but more importantly, a scalable business.”
De Souza himself added: “I had a great time with BGO and would like to thank the company for the memories and experience.
“The time was right to move onto a new challenge. As ever, with change comes opportunity and I believe joining a strong tech focused disruptor platform like MrQ, presents multiple opportunities as they continue to challenge other brands.”
De Souza’s role will include working on MrQ’s expansion into new markets. Currently it operates in Great Britain under remote bingo and casino licences from the Gambling Commission.
