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.

How we work
Partners, not a vendor
We’re not a faceless corporation. We know the sector, and we shape everything in dialogue with you — nothing off-the-shelf.
No cloud, just our machines
There is no cloud — only other people’s computers. Your sensitive data stays on encrypted machines in our office.
Built to be used
We turn analysis into clear, automated decision aids your whole team can act on — insight that gets used, not filed away.
