| description | Validate startup ideas using the Kevin Hale/YC framework and Tom Bilyeu's 60-minute method—Mom Test interviews, GO/PIVOT/KILL decisions, and real founder case studies. Use when testing whether a problem is worth solving, designing customer interviews, or deciding whether to commit to an idea. |
Idea Validation
Core Principle
The goal isn't to prove your idea is good. It's to find out how it's wrong before you waste six months building it.
Kevin Hale / YC Validation Framework
Every startup idea must pass three gates:
1. PROBLEM — Is this a real problem people pay to solve?
2. SOLUTION — Does your approach solve it better than alternatives?
3. INSIGHT — What do you know that others don't?
The Idea Matrix
| Dimension | Weak Signal | Strong Signal |
|---|
| Problem frequency | "Sometimes annoying" | "Deal with this daily" |
| Existing solutions | "Nothing really" | "I cobbled together 3 tools" |
| Willingness to pay | "That would be nice" | "How much? When can I start?" |
| Urgency | "Eventually, maybe" | "I needed this yesterday" |
Tom Bilyeu's 60-Minute Validation
Sprint through in one hour:
0:00–0:10 Write the problem in one sentence. If you can't, stop.
0:10–0:20 List 5 people who have this problem RIGHT NOW.
0:20–0:40 Contact 3 of them. Ask: "How are you solving this today?"
0:40–0:50 Identify what they hate about current solutions.
0:50–1:00 Write your unique insight — what you'd do differently and why.
Mom Test Interview Scripts
The Mom Test (Rob Fitzpatrick): never ask if your idea is good. Ask about their life.
Questions That Work
"Tell me about the last time you dealt with [problem]."
"What did you do about it?"
"What else have you tried?"
"How much time/money does this cost you?"
"If you had a magic wand, what would you change?"
Questions That Lie
| Bad Question | Why It Lies | Better Version |
|---|
| "Would you use this?" | People are polite | "How are you solving this today?" |
| "Would you pay $X?" | Hypothetical money isn't real | "What do you pay for [current solution]?" |
| "Do you think it's a good idea?" | They'll say yes to be nice | "What would make you switch from [current tool]?" |
| "How often do you have this problem?" | They'll exaggerate | "When was the last time this happened?" |
Interview Structure
1. Anchor in reality: "Tell me about the last time..."
2. Go wide: "What else have you tried?"
3. Go deep: "Why didn't that work?"
4. Find the money: "What does this cost you in time/dollars?"
5. Close with commitment: "Can I follow up when we have something to show?"
GO / PIVOT / KILL Decision Criteria
After 10+ interviews, score honestly:
GO (Build It)
PIVOT (Change Direction)
KILL (Walk Away)
Case Studies
Vanta (Compliance Automation)
Problem validated: Startups losing enterprise deals over SOC 2.
Signal: Founders said "I'd pay anything to not deal with this."
Insight: Compliance is repeatable → automate the evidence collection.
Validation method: Sold annual contracts before writing code.
Flexport (Freight Forwarding)
Problem validated: Freight brokers using fax machines and spreadsheets.
Signal: Customers spending 10+ hours/week on manual tracking.
Insight: Software-first freight forwarding with real-time visibility.
Validation method: Manually brokered first shipments to learn the workflow.
Anti-Patterns
| Validation Theater | Real Validation |
|---|
| Survey with 1,000 strangers | 10 deep conversations with target users |
| "Everyone I asked loves it" | "3 people offered to pay before I built it" |
| Building MVP first, validating later | Validating the problem before writing code |
| Asking friends and family | Asking people who have the problem today |
| Counting sign-ups on a landing page | Measuring commitment: money, time, or reputation |
Power Move
"Before I build anything, help me design a 5-question Mom Test interview for [target customer]. Then define GO/PIVOT/KILL criteria I should evaluate after 10 conversations."
The agent becomes your validation coach — structuring discovery so you learn the truth, not just what you want to hear.
