Bubble SaaS Customer Interview Guide
One customer interview is worth more than a month of analytics. Five interview types mapped to SaaS stages, the five questions that produce real insight, and why customer language from interview transcripts is your best marketing copy.
One Customer Interview Is Worth More Than a Month of Analytics
Analytics tells you what customers did. Customer interviews tell you why. The why is what determines what to build next, what to charge, how to position the product, and whether the business model makes sense. A builder who talks to customers every week makes better product decisions than a builder who does not talk to customers at all, regardless of how sophisticated their analytics stack is. This guide teaches you to run customer interviews that produce actionable insights, not just interesting stories.
Five Interview Types and When to Run Each
| Interview Type | When to Run It | Primary Question | Expected Output |
|---|---|---|---|
| Discovery Interview | Before building; to validate a problem | “Walk me through the last time you faced [problem].” | Problem confirmation, pain severity, current workarounds |
| Activation Interview | Day 7–14 of trial; user has used but not converted | “What did you come here to accomplish? Did you accomplish it?” | Activation blockers, missing features, onboarding gaps |
| Conversion Interview | Within 24 hours of a trial converting to paid | “What made you decide to upgrade today?” | Value realisation moments, conversion triggers, key features |
| Churn Interview | Within 48 hours of cancellation | “What was the final straw that made you cancel?” | Churn reasons, competing products, feature gaps |
| Power User Interview | Monthly; with your most engaged customers | “What would make [Product] worth twice what you pay today?” | Expansion opportunities, enterprise features, pricing ceiling |
The Questions That Produce Real Insight
“Walk me through the last time you [did the thing my product helps with].”
This is the single most powerful research question available. It asks for a specific, recent, real memory rather than a general opinion or a hypothetical. Specific memories contain detail, emotion, and context that general opinions lack. Listen without interrupting. Let them finish the story completely before your next question.
“What were you doing before [Product]?”
Understanding the alternative reveals the switching cost, the pain level, and the baseline they are comparing you to. If the alternative was a spreadsheet, you are replacing a free tool — value must be overwhelming. If the alternative was a $300/month enterprise tool, $99 feels like a bargain to them already.
“What almost stopped you from signing up/buying/using it?”
The most valuable objections are the ones you do not know about. This question surfaces the near-misses: the concerns that almost prevented conversion that the customer never voiced until you asked. These are your highest-priority landing page and onboarding improvements.
“If [Product] disappeared tomorrow, what would you do?”
The answer reveals your true competition and your true value. “I’d go back to spreadsheets” means your value proposition is clear but insufficient switching cost. “I would be in serious trouble — I’d have to [painful alternative]” means you have stickiness. The emotional weight of the answer reveals your product’s actual importance in their workflow.
“Who else in your world has this same problem?”
The referral question, asked naturally at the end of a positive conversation. Not “would you refer us to someone?” but “who else do you know that deals with this?” People who answer this question immediately, with specific names or companies, are your best referral sources. Follow up with “would you be comfortable making an introduction?”
Record and Transcribe Every Interview
Ask permission to record, use Otter.ai or a similar tool, and read the transcript within 24 hours while the conversation is fresh. The transcript surfaces exact phrases customers use to describe their problems — phrases that belong on your landing page, in your email subject lines, and in your sales conversations. Customer language converts better than marketing language because it is already the vocabulary your prospects use when they search for solutions.
