About Ground Truth Solutions
Our mission is to ensure that people affected by crises have a say in humanitarian action, from individual aid projects to global humanitarian reform. To achieve this, we collect feedback from people at the receiving end of aid. We challenge and encourage aid agencies to use this feedback to optimise their work. We influence policymakers, governments, and aid agencies to bring change to the humanitarian, health and environmental sectors.
About our work culture
We are a committed team of professionals who take the responsibility of receiving funds to work toward aid reform seriously. We strive for excellence, constantly challenging the status quo (internally and externally), and conducting ourselves with discipline, creativity, curiosity, boldness and candour.
