One Number, Not a Dashboard of Twenty
Your North Star metric is the single measure that best captures the value you deliver to customers — not revenue (a lagging indicator) but something upstream that predicts it. "Weekly Active Teams" beats "signups" because it captures ongoing value delivery, not just a moment of interest.
A good North Star metric has a current value and an explicit target — turning vision from aspiration into a number your whole team can rally around and see move (or not) every week.
