Private Investigator
Manhattan, NY
A new office in Manhattan, New York, takes the New York Intelligence Agency (NYIA) a big step forward. It’s not just about moving in; it’s about what drives and shapes the interaction of intelligence with the communities that make up the borough—and, by extension, the city itself.
Engaging with Manhattan’s innovative community—the agency is looking there for the same opportunities other intelligence offices and government agencies are finding in “open lab” environments—could yield fresh ideas that help the NYIA scale what it does and, hopefully, do it better.
This office might be just what the NYIA needs as it tries to expand its footprint (and, presumably, the effect it has) in the areas where its operates.
