Tilly joined the business in August 2020 and served as its legal chief for 18 months before accepting the new position.
Prior to this, Tilly was chief executive for Argyll Entertainment AG, a British-licensed online sports betting and gaming business acquired by Esports Entertainment Group in October 2020.
Tilly also founded mobile games developer Flip Sports and still serves as chief executive of the business.
In addition, he is a founding member of the International Social Games Association, an industry trade body for the social gaming industry, and is both founder and executive director of iGaming Counsel, a legal and commercial advisory firm to the online gaming industry.
“Having played a role in the burgeoning expansion of the company’s operations through our M&A activity since joining the company in the summer of last year, I’m incredibly excited to now be entrusted with overseeing the next stage of the company’s operational growth as we look to maximise the potential of our business assets and execute on our long-term goals,” Tilly said.
Esports Entertainment Group chief executive Grant Johnson added: “Given the remarkable growth in the size, breadth and geographical reach of our operations and staff over the last 18 months, we had long identified this operations role as a critical one in enabling the company to achieve its long-term strategic goals.
“With Stuart’s extensive igaming knowledge, first-hand experience of launching and growing businesses together combined with his legal and regulatory background, we felt he was the ideal fit for this position.”
The appointment comes after Esports Entertainment Group last week received approval from New Jersey’s Division of Gaming Enforcement to begin accepting bets in the state.
The operator was granted a transactional waiver, making it the first esports operator to receive a transactional waiver in New Jersey.
