The opportunities for economic growth in the region are incredibly limited (40%+ unemployment; 40% below the poverty line; 80% dependent on some kind of foreign aid; ~50% dependent on UN food aid alone; extreme barriers to importing or exporting physical goods), and yet they enjoy relatively high levels of infrastructure and education (97% literacy; 20% population with a college degree - higher than in the West Bank; female/male near-equality w/r/t education levels; decent internet). All of this combines to make tech investments especially appealing.
I got the feeling in Gaza - relative to many other countries lacking these resources that have garnered a great deal of attention from the tech community in recent years, such as India, Brazil, and more - that the development of tech companies (especially tech, due to minimal infrastructure needs) there can make a significant contribution to the regional economy. The group's additional devotion to including women in the accelerator is especially laudable, and has contributed to an incredibly rich workspace.
