The most expensive thing in growth is a pilot that should have died but didn’t.
I’ve seen it at every scale: a channel that never earned its keep, kept alive because someone championed it, because the team built familiarity with it, because killing it felt like admitting failure. Months pass. Budget compounds. The zombie persists.
The pilot discipline is the antidote. It’s not complicated, but it requires a commitment most organizations resist: you write the kill criteria before you spend the first dollar.
What Kill Criteria Actually Means
Kill criteria are specific. Not “we need to see positive ROI.” That’s not a criterion, that’s a hope. Kill criteria sound like:
“If we have not hit a cost-per-acquisition below X by week 8 with a minimum of Y in spend, the pilot ends.”
The specificity is the point. The moment you write it down before launch, you’ve committed to a decision rule that doesn’t require a meeting to interpret later. The number either hit or it didn’t.
Why Organizations Resist This
The resistance is understandable. Writing kill criteria in advance means accepting, up front, that this pilot might die. It names the failure condition. Teams that have already started believing in a channel don’t want to put a stake in the ground that might be used to kill it.
But that discomfort is precisely the point. If you’re not willing to name the conditions under which you’ll kill it, you’re not running a pilot. You’re running an indefinite experiment with no end state.
The Fast Death Is the Good Death
When a pilot fails its kill criteria, the fast death is the good outcome. You spent weeks, not quarters, and you learned something concrete. The budget that would have fed a zombie goes to the next pilot, the one that might actually earn.
The businesses I’ve worked with that compound fastest are the ones where pilots die quickly and cleanly. The survivors are real. The infrastructure built on top of them is built on truth.
That discipline of writing the criteria, holding to them, and killing fast is what makes scale possible. Not the spend. Not the creative. Not the channel selection. The discipline.
