I think credit should also go to those in the community who applied for and successfully won grants for projects that were not their own. Making sure a larger EA donor was aware of a particular project is one way to beat (in a very collaborative sense) the larger grant-makers. It is basically doing active grant making but at low risk and low personal ability to fund.
I know one example which is Chris Chambers work on Registered Reports. The giving opportunity was picked up on / created by Hauke Hildebrandt in a Lets Fund report. The application to fund it was made by Jacob Hilton (who had no connection to the issue but just though someone should do an application) and the grant was given by the EA Infrastructure Fund (details here).
If others have more examples of this would be great to hear.
I haven't looked closely, but from a fairly-but-not-completely uninformed perspective, Tim's allocation of part of his donor lottery winnings to the Czech Association for Effective Altruism looks prescient and potentially unusually counterfactually impactful.
