# Compare customer and prospect feedback to see where they differ
OS [Olha Solonenko](https://www.askthecustomer.ai/blog/author/olha-solonenko) 28 October 2026 7 min read
To compare customer and prospect feedback, ask the same question of each group separately, then read the answers side by side. Customers describe what the product did for them. Prospects describe what they fear it might not do. The gap between the two shows where your messaging, onboarding or product story needs work.
Key takeaways
- Customers and prospects answer different questions, so blending their feedback hides the gap that matters.
- Ask the same six questions of each group, one group at a time, and compare the answers afterwards.
- Count different accounts rather than mentions, and note the evidence strength behind each side.
- Worries that only prospects raise are your best leads for messaging fixes and sales-call preparation.
- Treat the comparison as a map of where to look next, then confirm it by talking to real customers and prospects.

## The situation: why do customers and prospects tell different stories?
In World War II, the statistician Abraham Wald was asked where to add armour to bombers. The returning planes showed damage in certain places. Wald advised armouring the places with no damage, because planes hit there never came back, so they were missing from the sample (see [John D. Cook's summary of the Wald story](https://www.johndcook.com/blog/2008/01/21/selection-bias-and-bombers), which dates Wald's study to 1943).
Customer feedback has the same blind spot. You hear from the people who stayed, not the ones who hesitated and walked away.
Even among those who buy, the story changes after purchase. Bain's 2018 write-up of its B2B elements of value research found that buyers weigh subjective factors, such as reducing anxiety, as well as price and performance ([Bain, 2018](https://www.netpromotersystem.com/insights/the-surprising-forces-driving-business-customers-nps-linkedin)). Anxiety is loudest before the purchase. Afterwards, customers talk about results.
That's why one blended pile of feedback misleads. It averages the doubts of people deciding with the experience of people already using.
## What questions should you ask of customer and prospect evidence?
Ask each question of your customer evidence, then of your prospect evidence. Then compare.
| Question | Why it matters | What a useful answer looks like |
| --- | --- | --- |
| What problem made them start looking? | It shows whether prospects are shopping for the same problem customers solved. | The same problem in similar words, or a clearly different one. |
| What almost stopped them from buying? | Customers remember the hurdle they cleared. Prospects are facing it now. | A short list of hurdles, with the ones only prospects raise marked. |
| What result do they say matters most? | Customers talk about outcomes they have seen. Prospects talk about outcomes they hope for. | Two ranked lists that you can read next to each other. |
| Which words do they use for the value? | Differences in vocabulary often explain why copy lands with one group and not the other. | Exact phrases from each group, each with its source. |
| Which worries come up only among prospects? | These are the objections your sales team meets and your customers have already forgotten. | Named worries that appear in prospect records and not in customer records. |
| What can the evidence not tell us yet? | It stops you from reading a gap that is really missing data. | An honest note on thin areas, plus who to talk to next. |
*Ask each question in both views, then compare the answers.*
## How to do it in Ask The Customer
1. **Upload your evidence.** Add interviews, call transcripts, tickets and notes as files or a ZIP. Each record is classified as Customer, Prospect or Unknown, and the two groups are never blended. Check the labels and reclassify any that look wrong.
2. **Ask the question in the customer view.** Pick "across current customers" in the scope selector and ask your first question. Each answer lists the records it used and shows the evidence strength.
3. **Compare it with the prospect view.** Use "Compare this question with" and choose the prospect view. The two answers appear side by side. Switch the market lens off if you want only your own evidence.
4. **Open the records and note the gaps.** Read the sources behind each difference. Ask the follow-up "What evidence is missing to answer this confidently?" and download the comparison as HTML if you want to share it.
> **Illustrative example:** A mid-size software company uploads call notes and interviews. It asks, "What almost stopped you from buying?" in both views. Customers mention a heavy setup that the team got through. Prospects raise data migration and who owns the rollout, and none mention setup time. Evidence strength is medium for customers and low for prospects, so the prospect side is a lead to confirm in calls.
## How to do it without a tool
You can run the same comparison in a spreadsheet. Make one tab for customers and one for prospects. Paste in each note, call summary or ticket, with the account name and date.
Then go through your six questions one group at a time. Write the answer in the buyer's own words, with the source. Count different accounts, not mentions, as in our guide to [prioritising feature requests from customers](https://www.askthecustomer.ai/blog/how-to-prioritise-feature-requests-from-customers).
Finish with a third tab that lists the differences. Mark each as strong or thin by the number of accounts behind it. For prospect worries, [this use case on preparing for a discovery call](https://www.askthecustomer.ai/blog/use-case-prepare-discovery-call-with-past-objections) shows how to turn them into questions.
## Where does this work, and where doesn't it?
It works best when you hold evidence from both groups.
It doesn't work when one side is missing or thin. With only customer evidence you can't say what prospects worry about, and the answer should say so.
Words from prospects describe expectations, not experience. Treat the gap as a hypothesis. Test it with real people, using the methods in [how to validate a product idea before building it](https://www.askthecustomer.ai/blog/how-to-validate-a-product-idea-before-building-it). AI can support that thinking. It doesn't replace the conversations.
## FAQ
### Why compare customer and prospect feedback instead of combining it?
Customers have already bought and adapted, so they describe results. Prospects are still deciding, so they describe doubts. Combining the two averages away both stories. Keeping them apart shows which promises land, which worries go unanswered, and where messaging and experience drift apart.
### What if customers and prospects disagree?
Disagreement is the useful part. Check each side's evidence strength first, because one side may rest on very few records. If both are solid, the difference usually points to a messaging gap, an onboarding surprise or a worry that fades after purchase. Then test it in real conversations.
### How much evidence do I need on each side?
There is no magic number. What matters is how many different accounts back each claim, not how many mentions. A theme from one loud account is a weak signal. If either side is thin, say so plainly and collect more conversations before you act.
### Can I compare feedback if I only have customer interviews?
Not fully. With only customer evidence you can see what customers value, but not what prospects worry about. Use what you have to draft questions, then book a few conversations with people who are still deciding, or who chose someone else, to fill the gap.
### How does Ask The Customer classify customers and prospects?
When you upload evidence, each record is classified as Customer, Prospect or Unknown, and the two groups are never blended in an answer. You can ask across customers, across prospects or across everything, and compare two views side by side. You can also reclassify a record if the label is wrong.
### Does this replace talking to prospects and customers?
No. Comparing existing evidence tells you where to look and what to ask. It cannot tell you what people think about something they never mentioned. Use it to prepare better interviews and sales conversations, not to skip them, and talk to real people before you decide.
