Ask HN: How can I help the victims of ISIS?

I am a startup founder based in Switzerland, Europe. I don't pretend to know a lot about ISIS and their role in the Syrian crisis, but it does seem to me that the best policy is to wait it out and not aggravate the situation with western boots on the ground.

Given that I am a startup founder, I don't have much time or spare cash with which to support the refugees and victims of ISIS, however I would like to do what little I can - is there perhaps somewhere a list in the Internet of 'effective' charities or smaller steps which I can take to help?

This would be a great resource that I could also share with friends etc.
