Bewley joined Sportech after its 2019 acquisition of LOT.TO – an iLottery solutions company which Bewley co-founded.
Bewley said: “I am proud of the progress that the team made during my time with Sportech.
“We managed to navigate through a challenging period, and the fact that the future looks bright for both clients and colleagues, is highly rewarding. I am grateful to have had this experience and wish the company well with its future endeavours.”
Sportech CEO Richard McGuire added: “Julian was instrumental in recognising the need to evolve and drive digital innovation across the group.
“He played a pivotal role in negotiations leading to the announced deal with BetMakers, and I am grateful for what he contributed during his time at Sportech.”
Bewley’s departure follows Sportech agreeing to sell its Global Tote business to BetMakers for a total cash consideration of £30.9m. New York-based investment fund Standard General had previously made two offers to acquire the business, but both a 28.5 pence per share offer and a 32.5 pence per share deal were rejected.
