Staff had a more innovative mindset than most USAID-funded orgs I know, more open to new ways of working, better at adopting new tools.
Cons
In the end, they're still bureaucratic and the bureaucracy of their major funders (USAID and the Gates Foundation) means PATH is bureaucratic also, admin processes like recruitment are slow, and they're always chasing the funding instead of doing the right thing for the project and the client country.
