Built on published work
The pair-chemistry research we start from is public and citable. We improved on it in the open, rather than inventing a black box and asking you to trust it.
Interactional data lets you create a well-matched team, not just a group of talented individuals.

The pair-chemistry research we start from is public and citable. We improved on it in the open, rather than inventing a black box and asking you to trust it.
Models are developed and challenged with researchers active in the field, not signed off by the same people who built them.
We write down what we expect each signal to do before we run the test. It keeps us honest about what the data actually showed.
Every signal has to beat a talent-only model on seasons it has never seen. If it adds nothing, it doesn't ship.
When a signal doesn't hold up, we say so. You'll know which parts of the model are strong and which are still soft.
No number arrives bare. You see how certain the model is for that pair, so you know when to lean on it and when to go and watch the player.
Questions
That is the whole point. Gaffer reads how each player plays: style, role, movement, the actions they take, then predicts how the two will combine. It doesn't need shared minutes, so it works for the signing you're deciding on, not just the pairs already in your squad.
Your squad and your scouts. Link the players you already have and the reports your scouts write, and you're set up. The interactional data comes from us, so there is nothing for your club to collect, build or maintain.
The underlying mechanism is grounded in peer-reviewed research. Gaffer's own research team improved on this research and is the first to put it in a club's hands. Every score ships with its confidence.
We cover all professional leagues and then some. We are always in the process of onboarding new leagues.
