What are your favorite NGOs/Social Enterprises in (Kigali)

Hi, all. Like the subject says, I'm wondering what your favorite NGOs/Social Enterprises are in Rwanda. What organizations are the best in your mind in accomplishing their missions? Which are doing work that you're always excited to hear about or be a part of?
I ask because I'm hoping to move to Rwanda in the near future. I recently finished my contract in Kenya, and it's always been my experience that there's a ton of info that people on the ground know that isn't available to the rest of us. Hence me coming to pick your brains.
It'd be great to hear your experiences and to learn more about what the best organizations are in your opinion.
Thanks and I hope to meet you in person soon!
