This wiki began life as this EA Forum post. I have turned it into an open-access wiki so that people can continue to improve and update it. As I wrote in the original post, this is not a comprehensive list of every organisation which should be considered ‘EA-aligned’ (and this is probably not even a useful distinction to make anyway).
When creating the original list I stipulated that an organisation must meet at least one of these criteria to be included:
EA projects which don’t hire staff and national/local EA groups (some of which hire paid staff) are not included in this list.
When adding an organisation to the wiki, please ensure it meets at least one of the above criteria. Please also ensure that your entry fits with the formatting of the list (i.e. it is alphabetical, under the right heading, and includes a short description of the organisation as well as a link to its website). Thanks for your help!
