Koji's AI interviewer follows Mom Test principles automatically, probing past behavior instead of hypothetical opinions. Convert existing surveys at koji.so/kojify.","content":"The Mom Test, created by Rob Fitzpatrick, is a framework for conducting customer interviews that avoids the trap of getting polite lies. Its core rule: talk about their life, not your idea. AI-moderated interviews can apply Mom Test principles at scale, running dozens of customer discovery conversations simultaneously while maintaining the methodology's rigor.\n\n## The 5 Rules of the Mom Test\n\n1. **Talk about their life, not your idea** -- Ask about past behavior, not opinions about your product\n2. **Ask about the past, not hypothetical futures** -- \"Tell me about the last time...\" not \"Would you ever...\"\n3. **Listen more than you talk** -- The 80/20 rule: they should talk 80% of the time\n4. **Dig for specifics** -- \"Always\" and \"never\" need concrete examples\n5. **Understand the cost** -- How much time, money, or emotional energy do they spend on the problem?\n\n## Why the Mom Test Breaks at Scale\n\nThe Mom Test was designed for founder-led, one-on-one conversations. It breaks at scale because each interview takes 30-60 minutes of a founder's time, quality depends on the interviewer, analysis is manual, and consistency suffers across different interviewers.\n\n## How AI Interviewers Apply Mom Test Principles\n\n| Mom Test Rule | AI Implementation |\n|--------------|-------------------|\n| Talk about their life | System prompt focused on past behavior and real situations |\n| Ask about the past | Follow-up questions anchored to specific events and timeframes |\n| Listen more than talk | Short AI responses, long participant responses encouraged |\n| Dig for specifics | Probing depth of 2-3 follow-ups per question |\n| Understand the cost | Automatic probing on workarounds, time spent, money spent |\n\n## Mom Test Question Examples: Survey vs. AI-Adaptive\n\n| Bad Survey Question | Mom Test AI Question | AI Follow-up |\n|--------------------|---------------------|---------------|\n| \"Would you use our product?\" | \"Tell me about the last time you dealt with [problem]\" | \"What happened after that?\" |\n| \"How likely are you to recommend us?\" | \"Have you told anyone else about [solution]? What did you say?\" | \"Why did you frame it that way?\" |\n| \"What features do you want?\" | \"Walk me through your current workflow for [task]\" | \"What's the most frustrating part?\" |\n| \"Rate your satisfaction (1-10)\" | \"How satisfied are you? (1-10)\" + follow-up | \"You said 6. What would need to change for that to be an 8?\" |\n\n## Converting Survey Questions to Mom Test Format\n\nIf you already have a survey, [Kojify](/kojify) converts it and applies Mom Test methodology automatically:\n\n1. Visit [koji.so/kojify](/kojify)\n2. Paste your survey link or questions\n3. Koji maps your questions and adds Mom Test-style probing\n4. The AI interviewer follows up on every answer with behavior-focused questions\n5. Publish and collect rich qualitative data at survey scale\n\n## Common Mom Test Mistakes the AI Avoids\n\n- **Pitching the solution** -- The AI never describes your product; it only asks about their experience\n- **Accepting compliments** -- When respondents say \"that sounds great,\" the AI probes for past behavior instead\n- **Leading questions** -- The AI asks neutral follow-ups: \"Tell me more\" not \"Don't you think that's a problem?\"\n- **Hypothetical futures** -- The AI redirects \"I would...\" to \"When was the last time you actually...\"\n\n## Further reading on the blog\n\n- [How Founders Validate Product Ideas with Customer Interviews (2026)](/blog/how-founders-validate-product-ideas-with-customer-interviews) — 42% of startups fail because they built something nobody wanted.
