Apologies for a quick answer, rather than a thorough answer where I looked up all the links and details, but one potential source:
I believe Charity Entrepreneurship partly see one
of their key outputs as being creating tangible achievements of the EA community. I guess a lot of it is still pretty new, but to the extent you can find any impressive achievements from CE-incubated orgs, those are pretty clearly attributable to EA. Fish Welfare Initiative have some impressive commitments from producers in India I think, and my impression was that some of the global health charities have achieved quite a lot in a small space of time.
