Personally, I like GiveDirectly—their work is research-backed and life-changing—and if you're interested in donating to them I'd appreciate if you did so through my weird little romantic art project (100% of your donation goes to GiveDirectly): https://helpmepropose.live
I'd love to learn about other great organizations!
