Where North Signal stands
Monitors show you the score.
We prove what moves it.
An honest comparison — including the things competitors genuinely do better. Every AI-visibility tool can tell you whether you were mentioned. Only a closed measure → prescribe → prove loop can tell you, with a held-out control, whether your fix caused the lift.
