SaaS User Research Playbook: Interview Techniques That Surface Real Insights
The best SaaS products are built on deep user understanding. But most founders either skip research entirely or do it so poorly they'd be better off guessing. Here's how to do it right.
This guide shares practical frameworks, examples, and next steps you can apply immediately.
The Mom Test: Questions That Work
The "Mom Test" (from Rob Fitzpatrick's book) is simple: ask questions that even your mom couldn't lie to you about. Instead of pitching and asking "would you use this?", focus on their actual behavior.
Bad: "Would you use a tool that does X?"
People will say yes to be polite. This tells you nothing.
Good: "How do you currently handle X?"
This reveals their actual behavior and current solutions.
Bad: "How much would you pay for this?"
Hypothetical pricing questions get hypothetical answers.
Good: "What do you currently spend on solving this?"
Real spending reveals real value and budget.
The 30-Minute Interview Structure
A well-structured interview covers three phases:
1. Context (5 min)
Understand who they are and their relevant background.
- • "Tell me about your role and what you're responsible for"
- • "Walk me through a typical day/week"
- • "What tools do you use regularly?"
2. Problem Exploration (15 min)
Dig deep into the specific problem area you're investigating.
- • "Tell me about the last time you had to deal with [problem]"
- • "What made that difficult?"
- • "What have you tried to solve this?"
- • "Why didn't that work?"
3. Wrap-up (10 min)
Summarize and open for additional insights.
- • "What's the single biggest frustration with [topic]?"
- • "Is there anything I should have asked but didn't?"
- • "Who else should I talk to about this?"
Finding Research Participants
Finding people to interview is often the biggest hurdle. Here are proven methods for SaaS products:
For B2B SaaS
- LinkedIn outreach - Direct messages to people with relevant job titles
- Industry communities - Slack groups, Discord servers, forums
- Your network - Ask connections for introductions
- Conference attendees - People at industry events are often happy to talk
For B2C SaaS
- Social media - Twitter, Reddit communities, Facebook groups
- User testing platforms - UserTesting.com, UserInterviews.com
- Existing customers - If you have any, they're your best source
Pro tip: Offer something in return—a gift card, early access, or simply genuine gratitude. Most people want to help if you make it easy.
Synthesizing Research Into Insights
Raw interview notes aren't research. The value comes from synthesis—identifying patterns across conversations and translating them into actionable insights.
The Affinity Mapping Process
- Extract quotes and observations - Pull specific statements from each interview
- Group similar items - Cluster related observations together
- Name the clusters - What theme does each group represent?
- Identify insights - What do these patterns mean for your product?
- Prioritize - Which insights are most important to act on?
The pattern test: If you hear the same thing from 3+ different people, it's probably real. If only one person mentions it, it might be personal preference rather than a market need.
Key Takeaways
- 1Talk about problems, not solutions. The moment you pitch your idea, you stop learning.
- 2Five interviews can reveal 80% of usability issues. You don't need hundreds of participants.
- 3Watch behavior, not just words. What users do often differs from what they say.
- 4Synthesis is where insights live. Raw notes aren't research—patterns are.
- 5Make research a habit, not a project. Continuous discovery beats annual studies.
