Every churn survey asks a version of the same question - why did you leave - and gets a version of the same answer: “it wasn’t the right fit,” “we’re going a different direction,” “nothing against you.” The customer who just cancelled has already mentally exited and has no incentive to be specific on the way out. They’re being polite to someone they’ll probably never talk to again.
The customer who picked a competitor over you two years ago and is still there is a different kind of source entirely. They made the comparison when it actually mattered, lived with the decision long enough to know if they got it right, and have nothing to lose by telling a stranger from the company they didn’t choose exactly why.
Your own churn data is filtered twice before it reaches you
It’s filtered once by the customer, who softens the real reason because conflict is uncomfortable and they’re already halfway out the door. It’s filtered a second time by whoever on the team reads the survey, who has an incentive - often unconscious - to read “pricing” as the answer more often than “your product was worse,” because pricing is a less personal thing to have to fix.
A competitor’s long-tenured customer has no such filter running. They’re not leaving anything. They’re just explaining a choice they made once and have had years to form an unsentimental opinion about.
The call is harder to get and worth more because of it
This isn’t a survey you can automate. It means finding someone in your own network who uses the competitor, or a customer who evaluated both and picked the other one for a specific reason they’ll actually name - and asking them plainly what convinced them, and whether they’d make the same call today. Most founders never make this call because it feels like asking someone to criticize a choice they’re not responsible for defending, which is uncomfortable. That discomfort is exactly why almost nobody does it, and exactly why the handful of founders who do come back with the sharpest, least self-serving read on their own weak points available anywhere.
What you’re actually buying is the comparison, not the opinion
The point isn’t that the competitor’s customer is right and your churned customer is wrong. It’s that a decision made in comparison, under no pressure to soften it, and defended for years afterward tells you more about where you actually lose than an exit survey filled out by someone trying to leave the conversation as quickly and kindly as possible.
