Good intro for PRO (Project Resource Optimization), a group spun up in the post-USAID moment by two former development economists. 

PRO is backfilling certain programs that cross a pretty demanding bar; they're familiar w/ GiveWell and the EA space and their evaluation framework would be familiar here.

Not sure how to compare their effectiveness to GiveWell's All Grants; or to other bridge funds. Anyone done any research or have any thoughts here?

(One small detail - the speaker (Rob Rosenbaum)'s role at USAID was funded by OpenPhilanthropy. I'd love to understand how that worked!)
