Define the loop narrowly
One customer archetype, one buying trigger, one moment in their journey, chosen from two or three candidates. In a randomized trial, founders taught to treat their ideas as hypotheses to test were more likely to drop or change weak ones.
Design the play end to end
The message, the story (context, pain, implication, proof, next step) and the play sellers can run. A story that draws people in tends to persuade more than a list of claims.
Instrument it, with a stop rule
One leading signal, an owner, a weekly review, and the level at which the team continues, adjusts or stops, set before the loop runs. Fast, small tests tend to go with faster growth, and deciding in advance tends to guard against sinking more into a loop because of what’s already spent.
