Why customers actually leave

1 June 2026

Every churn intervention is a bet on a diagnosis, and most founders make the bet without making the diagnosis. This is how to find out why people are actually leaving — including why the cancellation survey lies to you, and what to do instead of believing it.

The short version
  • The five causes: never activated, need changed, value faded, someone left, and price got noticed. Each needs a different fix and most companies apply one fix to all five.
  • 'Too expensive' on a cancellation form usually means 'not worth it', which is a value problem wearing a price costume. Discounting it makes things worse.
  • The biggest single cause in most self-serve SaaS is that the customer never got the product working in the first place — churn that was decided in week one and processed in month four.
  • Cancellation surveys have terrible data quality: the respondent is annoyed, in a hurry, and picking whatever option ends the interaction fastest.
  • The good data comes from a short interview with someone who left three weeks ago, and from usage data in the sixty days before the cancellation, not from the form.
