I see essentially two distinct things here.
First, you have the umbrella organization, offering fiscal sponsorship for other organizations. Based on what I know from the charity space, this is a highly valuable service \- it was very annoying getting Balsa a fiscal sponsor while we waited to become a full 501c3, even though we ultimately found a very good one that did us a solid, and also annoying figuring out how to be on our own going forward.
Second, you have various projects around Prague, which seem like solid offerings in that class of action of building up EA-style x-risk actions in the area, if that is what you are looking for. So you’d be supporting some mix of those two things.
To donate, contact hello@epistea.org.
