Top 14 'Truth-Telling' Customer Interview Questions to learn for Founders to Uncover What Users Really Want - Goh Ling Yong
You’ve got a brilliant idea. It’s a game-changer, a paradigm-shifter, the kind of concept that keeps you up at night, sketching on napkins and coding until 3 AM. You’re ready to build. But hold on. Before you write a single line of code or design the perfect logo, you need to answer the most terrifying question in the startup world: Will anyone actually use this?
The common advice is "talk to your customers." So you do. You schedule calls, buy coffees, and excitedly pitch your vision. They nod, they smile, they say things like, "Wow, that's a great idea!" or "I would totally use that!" You walk away feeling validated, a surge of adrenaline confirming you're on the right track. Unfortunately, you’ve just fallen into the most dangerous trap for a founder: mistaking politeness for market demand. Compliments are poison. They don't pay the bills, and they won't build a sustainable business.
The truth is, most people are nice. They don’t want to crush your dreams. But you’re not looking for a friend; you’re looking for the truth. You need to become a detective, skillfully digging for facts about your customers' lives, problems, and past behaviors—not their opinions about your hypothetical future. As I've seen countless times in my work, the difference between a successful startup and a failed one often comes down to the quality of the questions the founder asks. This is where "truth-telling" questions come in. They are designed to bypass the fluff and get to the heart of what users really want, need, and are willing to pay for.
Here are the top 14 truth-telling customer interview questions every founder needs to learn.
1. "Walk me through the last time you..."
This is the gold standard of customer interview questions, and for good reason. It immediately grounds the conversation in a real, specific memory. Instead of asking a hypothetical question like, "How do you usually manage your projects?", which invites a generic and idealized answer, you're asking for a story about a concrete event.
When you ask someone to recall a specific instance, they are forced to remember the details: the context, the frustrations, the workarounds, and the emotions involved. This is where you'll find the unvarnished truth. You're not just learning what they do; you're learning how and why they do it, which is infinitely more valuable.
Pro Tip: Be specific with your prompt. For example:
- "Walk me through the last time you had to create a report for your boss."
- "Tell me about the last time you tried to book a group vacation with friends."
- "Can you describe the process you went through the last time you hired a freelancer?"
Listen for pauses, sighs, and phrases like "Ugh, and then I had to..." These are emotional cues that point directly to the pain points your product could solve.
2. "What was the hardest part about that?"
This is the perfect follow-up to the "walk me through" question. Once they've finished telling their story, you can zoom in on the specific moments of friction. This question is beautifully simple and direct. It explicitly asks the user to identify their biggest struggle within the context of the story they just told you.
Avoid leading questions like, "Was it difficult when you had to export the data?" This puts words in their mouth. By asking "What was the hardest part?", you leave it completely open-ended. You might be surprised by the answer. You might think the data export was the main issue, but they might tell you the hardest part was getting approval from their manager beforehand. This insight can completely change your understanding of the problem.
Example: After they walk you through creating a report, they might say, "The hardest part was definitely getting the sales and marketing data into the same format. They use completely different systems, and I spent hours just copying and pasting." Boom. That’s a real, tangible problem.
3. "What have you already tried to solve this problem?"
This question is my personal litmus test for whether a problem is worth solving. Ideas are cheap, but action is telling. If a person claims a problem is a massive headache, but they’ve done absolutely nothing to try and fix it, the pain might not be as severe as they say.
People who are genuinely struggling with a problem will have tried something. They might have cobbled together a messy Excel spreadsheet, tried a competitor's product, or even hired an intern to handle it. These attempts are proof of motivation and, more importantly, a willingness to invest resources (time or money) into a solution.
What to listen for:
- Specific tools: "We tried using Asana for a bit, but it was too complex." (This tells you about a competitor and a potential objection).
- DIY solutions: "I have this crazy spreadsheet with like 15 tabs and a bunch of VLOOKUPs." (This shows desperation and a clear workflow you can improve upon).
- Doing nothing: "Yeah, it's annoying, but we just kind of deal with it." (This is a major red flag. The problem isn't urgent enough).
4. "How much are you currently spending to solve this (in time, money, or resources)?"
This question turns a vague problem into a quantifiable business case. A problem that costs a company $10,000 a month in wasted employee hours is a much more attractive opportunity than a minor annoyance. This question helps you understand the user's perception of the problem's value.
Don't just focus on money. Time is a currency, and so are resources. If a marketing manager spends 10 hours every week manually creating reports, that's a significant cost. You can even help them do the math: "So that's about 40 hours a month. If your time is worth, say, $50/hour, that's a $2,000/month problem."
This conversation naturally transitions into pricing. If you can prove your solution saves them $2,000 a month, charging them $200 a month suddenly seems like a no-brainer. This approach frames your price in terms of value and ROI, not cost.
5. "Tell me more about that."
This isn't so much a question as it is an invitation. It’s the most versatile and powerful follow-up in your arsenal. Often, a user will mention something interesting in passing. It's your job as the interviewer to notice these nuggets of information and gently encourage them to elaborate.
Using a neutral prompt like "Tell me more about that" or "Why was that the case?" avoids leading the witness and shows you're genuinely interested. It gives them space to explain their reasoning in their own words. You'll be amazed at the insights that surface when you stop talking and just listen.
Scenario:
- User: "And then I had to send the file over to the legal team, which is always a nightmare."
- You (Bad): "Is that because they're slow to respond?"
- You (Good): "A nightmare? Tell me more about that."
The second option allows them to explain the real issue, which might be about version control, file formats, or a specific difficult person—details you'd never have guessed.
6. "What were the consequences of that?"
This question helps you understand the "so what?" behind a problem. A problem is only a business opportunity if it has meaningful consequences. If the consequence of a mistake is a minor typo, it's not a big deal. If the consequence is a lost client, a compliance failure, or a million-dollar miscalculation, you've found a high-stakes problem.
This question moves the conversation from the problem to the impact of the problem. Businesses don't buy features; they buy outcomes. They buy risk reduction, cost savings, and revenue generation. Understanding the consequences helps you frame your value proposition in a language that decision-makers understand.
For example, if the problem is "it's hard to get the data in the right format," the consequence might be "the report was late, and my boss was furious, which made our team look bad in front of the executives." Now you're not just selling a data formatting tool; you're selling professional credibility and peace of mind.
7. "If you had a magic wand, what would you change about this process?"
This is one of the few future-facing questions that works because it's framed to uncover ideal outcomes, not specific feature requests. Asking "What features do you want?" often leads to users describing a faster horse instead of inventing the car. They'll just ask for incremental improvements on what they already know.
The "magic wand" question liberates them from the constraints of reality. It encourages them to describe their perfect world. In that description, you'll find the core value they're searching for. They won't say, "I want a button that exports to PDF." They'll say, "I wish I could just think of the report, and it would magically appear on my boss's desk, perfectly formatted and with all the latest data." The underlying desire is for automation, accuracy, and effortlessness.
8. "Why haven't you been able to solve this yet?"
This is a subtle but powerful variation of the "what have you tried" question. It probes for the obstacles. The answers will reveal the real barriers you're up against, which could be anything from budget constraints to internal politics to a lack of technical expertise.
The answers to this question can directly inform your go-to-market strategy.
- "We don't have the budget for new software." (Your pricing needs to be competitive, or you need to offer a freemium model).
- "Our IT department has a strict policy against new tools." (You need a strong security and compliance story, or maybe a sales process that targets IT directly).
- "We just haven't had the time to look for a better solution." (Your marketing needs to be incredibly efficient and clearly communicate value in seconds).
9. "How are you currently dealing with this?"
This is a must-ask question to understand the current landscape. No problem exists in a vacuum. Your product will have to displace an existing habit, tool, or workflow. You need to know what you're up against.
The answer might be a direct competitor ("We use Mailchimp"), a different category of tool ("We just use Google Sheets"), or a non-digital process ("We have a weekly meeting and use a whiteboard"). Each of these answers presents a different challenge. Displacing a complex spreadsheet is very different from displacing a deeply ingrained team ritual.
By understanding their current solution, you can tailor your product's messaging to highlight your specific advantages. For example, if they're using a spreadsheet, you can emphasize automation and collaboration features they're currently missing.
10. "What do you love and hate about your current solution?"
This question is a treasure trove of product insights. It helps you deconstruct the competition and their existing workarounds. The "hate" part is easy—that's a list of opportunities for you. These are the pain points and missing features you can build a better product around.
But don't ignore the "love" part. This is just as important. The things they love about their current solution are their "must-have" features. These are table stakes. If your product doesn't do these things at least as well as their current solution, they will never switch, no matter how innovative your other features are. This can save you from building a product that is technically superior but fails because it misses a single, critical workflow.
11. "Does this problem fall into your top 3 priorities to solve this quarter?"
Urgency is a key qualifier. A problem can be real and painful, but if it's #17 on a user's priority list, they won't have the time, budget, or political capital to champion a new solution. You need to find problems that are a "hair on fire" priority.
Asking this question forces the user to place the problem in the context of their other responsibilities. It's a fantastic way to gauge their true motivation. If they hesitate or say, "Well, it's something we'd like to get to eventually," that's a signal that you're talking to the wrong person or solving a problem that isn't pressing enough. If they say, "Yes, my boss is asking me for an update on this every week," you've found a motivated buyer.
12. "What's the budget for tools that solve this kind of problem?"
Talking about money can be awkward, but it’s essential. Avoid the vague question, "What would you pay for this?" People are terrible at predicting their own purchasing behavior. Instead, ground the conversation in their current reality by asking about existing budgets.
This question does a few things. First, it tells you if they even have a budget. If the answer is zero, you're likely looking at a freemium or ad-supported model. Second, it gives you a realistic price range to anchor your thinking. If companies typically pay $50/month for similar tools, pricing your product at $500/month will be a very tough sell unless you're providing 10x the value.
It also reveals who controls the budget. They might say, "I don't have a budget, but my manager does." This is a critical piece of information for your future sales process.
13. "Who else should I talk to about this?"
This is the perfect way to end an interview. It serves two purposes. First, it’s a great test of how well the interview went. If they found the conversation valuable and believe you're working on an interesting problem, they'll be happy to refer you to their colleagues or friends who face similar issues. If they give you a vague, non-committal answer, it might be a sign that the problem isn't as resonant as you thought.
Second, it’s the most effective way to build a pipeline for more customer interviews. A warm introduction ("I was speaking with Jane, and she suggested I reach out to you...") is far more effective than a cold email. Keep the chain going, and you'll quickly map out the entire ecosystem of your target users.
14. "What's a question I should have asked you?"
I love this question. It's a humble and brilliant catch-all that can uncover your biggest blind spots. You, as the founder, are inevitably biased. You have assumptions about the problem and the solution. This question hands the microphone back to the user and asks them, "What did I miss?"
Their answer can reveal a crucial aspect of the problem you completely overlooked, a key stakeholder you weren't aware of, or a competitor you've never heard of. It shows that you value their expertise and are there to learn, not just to validate your own ideas. It’s a final, powerful check to ensure you're not just hearing what you want to hear. I, Goh Ling Yong, have found that the insights from this one question can sometimes be more valuable than the rest of the interview combined.
Stop Selling, Start Learning
The goal of these customer interviews is not to sell your product. It's not even to validate your idea. The goal is to learn the truth about your customers' world. The best founders approach these conversations with the curiosity of a scientist and the empathy of a therapist.
These 14 questions are not a rigid script. They are a toolkit. The real skill is in the listening—in picking up on a thread and gently pulling on it with a well-timed "Tell me more about that." Your mission is to uncover the problems, pains, and priorities that are so significant that users have already tried (and failed) to solve them. Find that, and you've found the foundation for a great business.
So, take this list, get out of the building (or on a Zoom call), and start asking better questions. The future of your startup depends on it.
