Our mission
Too often, data is used to concentrate power — by corporations, platforms and political actors. We believe the same methods, in the right hands, can level the playing field. Used well, data analysis and honest metrics make non-profit work measurably more effective. Our mission is simple: help mission-driven organisations have the greatest possible impact.
