Churn Interviews

What is a Churn Interview?

A churn interview is a short conversation with someone who stopped being your customer, so you can find out what actually happened. Churn means customers leaving: cancelling a subscription, not reordering, or signing up and never really starting. The interview rebuilds their story from the day they signed up to the day they left, in their own words.

Cancellation surveys give you a tick box: “too expensive”. A 20-minute call gives you the real chain of events: they paid, couldn’t get their data imported, used it twice, forgot about it, saw the renewal charge, and THEN decided it was too expensive. Price was the last straw, and the import was the problem. Fix the import and the price complaint shrinks on its own.

When should you use it?

Use it as soon as people start leaving at a rate that worries you, or once your cohort retention curve keeps sliding instead of flattening.

• Fits: subscriptions and SaaS, apps, memberships, coaching or service retainers, online shops where repeat buyers stop reordering.
• Fits B2B especially well: one lost account can be a big share of revenue, and business customers expect a call.
• Include the never-started: people who signed up and didn’t activate are churn too, and there are more of them.
• Skip: if you have under 5 leavers. Talk to active users first through a customer feedback loop.

How do you do it, step by step?

1. Make three lists. Cancelled paying customers from the last 30 days, free sign-ups who never completed the main action, and customers who downgraded. Recent leavers remember details; after 60 days the story turns vague.

2. Send a short, human invite. From your own email, no marketing template: “Hi Lea, I’m the founder of [product]. I saw you cancelled last week, and that’s completely fine. I’m not going to try to sell you back. Would you give me 15 minutes to tell me what happened? It would help me fix things for others. Here’s my calendar: [link].” Offer a small thank-you if you can, like a €15 gift card. Expect roughly 1 in 4 to 1 in 5 to say yes, our rule of thumb, so invite 40 to get 8 to 10 calls.

3. Open by lowering the stakes. Start the call with: “There are no wrong answers, and nothing you say will hurt my feelings. The more blunt, the more useful.” Then ask permission to take notes.

4. Rebuild the timeline, start to finish. Ask in order: “What was going on when you first signed up?”, “What did you hope it would do for you?”, “What happened in the first week?”, “When did you start using it less?”, “What was the moment you decided to cancel?”, “What are you using instead now, if anything?”. Ask about what happened, in the past tense; a question like “Would you come back if we added X?” gets polite guesses.

5. Stay quiet and don’t defend. When they say the reminders didn’t work, the urge to explain the settings is strong. Write it down instead and ask “What happened then?”. One defensive answer and the rest of the call turns polite.

6. Offer help at the end, never at the start. Once the story is told, if there is a real fix (a bug you can solve, a feature they missed, a refund that’s fair), offer it plainly. Some will come back, and that’s a bonus. The interview’s job is the story.

7. Tag each interview with one main reason. Use a fixed list: never-got-value, setup-too-hard, missing-feature, price, switched-to-competitor, need-ended (the project finished or the season passed), bug, bad-timing. Add one supporting tag at most and a verbatim quote. After 8 to 10 interviews, count the main reasons.

What does a worked example look like?

Say Dana runs a bookkeeping app for hair salon owners at €19 a month. In two months, 22 salons cancelled and 60 sign-ups never connected their bank account. She invites all 22 cancellations and 25 of the never-started, and books 11 calls.

Her tag counts after 11 interviews:

The cancellation survey had said “price” for most of these same people. The calls tell a different story: 5 of 11 never got past setup, and both price complaints came from people who had used the app twice. Dana adds a CSV upload as a fallback when the bank connection fails and offers a 15-minute setup call to every new salon. She also learns that accountants influence the choice, which opens a partner idea for later.

At the end of each call she offered to fix the bank connection personally. Three salons took her up on it and two of them restarted their subscription.

Which free tools help?

What mistakes should you avoid?

• Trusting the cancellation form. “Too expensive” is the polite exit. The call finds the reason behind it.
• Selling during the interview. If they sense a retention pitch, they shorten their answers. Save any offer for the last two minutes.
• Asking about the future. “Would you use it if…” invites kindness. Ask what happened.
• Only calling paying cancellations. The people who never started tell you about the biggest leak. Invite them too.
• Changing the tag list every call. A shifting list makes counting impossible. Fix it after the first 3 calls and keep it.

How do you know it worked?

The interviews did their job when one reason clearly leads the count, you can back it with 3 or more quotes, and you have a concrete fix for it in progress.

Our rule of thumb for go / no-go: if a single main reason covers a third or more of your interviews, fix that first and re-check churn for the next two monthly cohorts. If the reasons scatter with no leader after 10 calls, your product is trying to serve too many different customers; narrow to the segment that stays, using your cohort retention data.

What should you do next?

Feed the tags into your customer feedback loop so leavers and stayers are counted the same way.

FAQ

What questions should I ask in a churn interview?

Ask about the past, in order: why they signed up, what they hoped for, what happened in the first week, when use dropped, the moment they decided to leave and what they use now. Follow every answer with “What happened then?”. Avoid questions about what they would do in the future.

How do I get churned customers to talk to me?

Write personally, from the founder’s address, say you won’t try to win them back, and ask for 15 minutes. A small thank-you helps. Invite within 30 days of the cancellation, while they still remember.

Should I try to win customers back during the interview?

Only at the end, and only with a real fix for the problem they described. The interview is for learning; a sales pitch in the middle cuts the story short. Customers who come back after a genuine fix are a welcome side effect.
