+## 🚀 30-Second Preview
+
+```
+You: We have 50 B2B SaaS customers. Want to validate PMF. Draft an interview plan.
+Agent (with gingiris-user-interview):
+  Phase 1 — Segment (Week 1):
+    • Power users (used 4+ weeks consecutively): 10 candidates
+    • Churned (canceled in last 30 days): 8 candidates
+    • Activated-but-stuck (low engagement after signup): 12 candidates
+
+  Phase 2 — Interview script (JTBD format):
+    1. "What were you doing the day you decided you needed [product]?"
+    2. "What did you try before you found us?"
+    3. "What almost stopped you from signing up?"
+    4. [...8 more, each mapped to PMF signal]
+
+  Phase 3 — Scoring:
+    • Strong PMF: 40%+ "very disappointed if removed" responses
+    • Weak PMF: <40% — pivot signal
+```
+
+Real framework from a $50M+ ARR exit — not vague "talk to users".
