Partnership on AI — Country: United States

Note: While the source provides extensive information about Partnership on AI's founding, members, and activities, it does not explicitly state the organization's country. The text mentions that founding members included US-based companies (Amazon, Facebook, Google, Microsoft, IBM) and that a founding executive director had prior experience with the US Chief Technology Officer, which suggests US connections, but this is circumstantial evidence rather than explicit confirmation. The claim requires a direct statement about the organization's country, which the source does not provide.
