Maiza cofounded Galactech in 2019, a Tunisian gaming startup that allows gamers in the country to access international gaming premium services. The company expanded to the U.A.E. and had more than 200,000 registered gamers in 2022. In early 2023, Galactech was acquired by GBarena, an online esports platform, for a $15 million share swap deal. Maiza was the co-CEO of the new parent company, “GBarena,” until June 2023. After Galactech rebranded to T7D Gaming, Maiza became the Managing Director of the business unit, which is leading the operations of the mother company in the Maghreb Region and Sub-Saharan Africa.
