This has a diagram showing the funding structure with 5 layers of bureaucracy between donors and the recipients of aid. This organization reduces that to 3 (The “coalition” that owns the website -> financial service providers -> mutual aid societies -> actual people in need).
So I ask again, have these people actually requested your help? How do you know what they actually need? Maybe the best solution is a way to gtfo of Sudan and let it collapse. Maybe they want weapons or chickens. I don’t know!
