Ground Truth Solutions is a non-profit organisation that provides the humanitarian sector with tools to systematically listen, learn, and act on the views of affected people. We also capture the perspective of field staff and local partner organisations as a counterpoint to the views of those caught up in humanitarian crises. Our goal is to make the perceptions of affected people the touchstone and driver of humanitarian effectiveness.
