We invited a total of 107 organizations to apply within our international causes (saving lives and global poverty). 59 complete our Round 1 application; 48 did not apply. Full details of how we found applicants, for all five of our causes, are available here.
Our Round 1 application asked each applicant to focus on a single well-documented project; our aim was to find the charities with the strongest self-documentation, and therefore the charities we had the best chance of understanding thoroughly (we also believe that self-documentation is valuable in itself for large organizations). Details on the criteria we used to choose finalists - along with the applications of all who applied, finalists and non-finalists - are available here.
Our analysis of finalists is still in progress, as explained here.
