Chapter 7: The Role of AI in Validation

Augmented discovery with PivotBuddy and the Lean Vault.

Playbook Chapters
What You'll Learn How to use AI to practice interviews, spot patterns in transcripts, and organize your learning.

AI as Your Research Partner

AI doesn't replace customer validation—it speeds it up. Used well, AI is a force multiplier.

AI can't talk to customers for you, but it's great at simulation, analysis, and patterns. Know what AI does well—and where it misleads.

AI Is Good At

  • Simulating personas for interview practice
  • Analyzing transcripts for patterns
  • Generating experiment ideas
  • Organizing and tagging insights
  • Finding hints in lots of data

AI Is Bad At

  • Replacing real customer conversations
  • Providing "ground truth" about markets
  • Making emotional connections
  • Understanding nuance and context
  • Predicting specific customer behavior

Using AI for Discovery

Here are three great ways to use AI when you're validating:

1. Persona Simulation

Practice your interview skills before talking to real customers.

Prompt: "Act as a busy CFO at a 50-person company. I'm going to interview you about your accounting software pains. Respond as that persona would—including being impatient and skeptical."

2. Transcript Analysis

Extract patterns from interview notes that humans miss.

Prompt: "Analyze these 5 interview transcripts. Extract: (1) recurring pain points, (2) emotional triggers, (3) 'Jobs to be Done', (4) workarounds they mentioned."

3. Experiment Design

Generate creative low-cost tests you might not have considered.

Prompt: "I have a Desirability risk: 'Do freelancers care about cash flow forecasting?' Suggest 5 low-cost smoke tests I can run this weekend with less than $100."
The AI Hallucination Trap

AI is a reasoning engine, not a truth engine. It sounds right but may be wrong.

Rule: Never use AI "feedback" as a stand-in for real humans. AI is for practice only—not validation.

The Lean Vault: Where Learning Lives

The Lean Vault is where you save what you learn. Without it, insights get lost in Slack, notebooks, and people's heads.

What Goes in the Vault

Experiments

  • Hypothesis tested
  • Method and sample size
  • Results and interpretation

Interviews

  • Transcripts or notes
  • Key quotes and patterns
  • Jobs to be Done discovered

Decisions

  • Pivot/persevere choices
  • Evidence that drove the decision
  • What we decided NOT to do

Artifacts

  • Landing pages tested
  • Ad copy and creative
  • Survey questions and results

AI can tag and sort these insights so your whole team can find and use them.

Weak Signal Detection

AI can scan social media, forums, and reviews for early signs of trends or gaps your competitors miss.

Let AI Watch for You

Set up AI to scan:

  • Reddit threads in your problem space
  • Twitter/X conversations with relevant keywords
  • Competitor review sites (G2, Capterra)
  • Industry Slack communities and forums

What to Look For

Look for:

  • Complaints about existing solutions
  • Workarounds people are building
  • Pricing objections to competitors
  • "I wish there was..." statements
The 10x Insight Rule

AI monitoring is a complement to real talks—not a stand-in. Use AI to find people and topics. Then talk to real humans. One real chat beats 100 AI summaries.

The Human-AI Balance

Use AI like a helper, not a crystal ball. Here's how to split the work:

Task AI Role Human Role
Interview prep Simulate personas, generate questions Conduct the actual interview
Pattern analysis Extract themes from transcripts Validate patterns make sense
Experiment design Brainstorm test ideas Choose and execute the test
Decision making Summarize evidence Make the pivot/persevere call

What You Walk Away With

  • AI Cheat Sheet: Know where AI helps and where it hurts.
  • Prompt Templates: Ready-to-use prompts for persona simulation, analysis, and experiment design.
  • Lean Vault Structure: A system for capturing and organizing all validated learning.
  • Weak Signal Hunting: How to spot trends with AI monitoring.
