Validate before you build. Here's the exact checklist.
Target: [YOUR ICP - e.g., "Solo founders building B2B SaaS"]
Channel: [LinkedIn DM / Reddit / Cold email / IndieHackers]
Q1: "Walk me through the last time you tried to [PROBLEM AREA]. What happened?"
Q2: "What's the hardest part about [PROBLEM AREA] right now?"
Q3: "How do you solve it today? What tools/workarounds?"
Q4: "If you could wave a magic wand, what would the ideal solution do?"
Q5: "Would you pay $X/month for that? Why / why not?"
Goal: 10 interviews → 3+ say "yes, I'd pay" → proceed.
Template DM:
Hey [name], building a tool for [ICP] struggling with [problem]. Not selling anything — just 10 min to understand your workflow. Happy to share what I learn. Interested?
Structure (single page):
Hero: [One-liner value prop] + [CTA: "Get Early Access"]
Problem: 3 bullets — "You're wasting X hrs/week on..."
Solution: 3 bullets — "Automate Y so you can..."
Social Proof: "Join 47 founders on the waitlist" (real number)
FAQ: 3 objections (price, time, complexity)
CTA: Email capture → redirect to "Thanks + 1 question survey"

Hi [name], saw your post about [pain point]. I'm researching a tool that [one-liner]. Would love 5 min of your time — no pitch, just learning. Can I send 3 quick questions?
I went through this exact problem last year. Built a quick validation framework that got me 10 paying users in 7 days before writing code. Happy to share the checklist if useful — no email gate, just a Telegraph page.

Goal: 3-5 pre-sales = green light to build.
| Signal | Kill | Pivot | Build |
|---|---|---|---|
| Interviews: "would pay" | < 2/10 | 3-4/10 | ≥ 5/10 |
| Waitlist conversion | < 5% | 5-15% | > 15% |
| Pre-sales (7 days) | 0 | 1-2 | ≥ 3 |
| Your excitement | Gone | Meh | Hell yes |
Rule: Two "Kill" columns = kill. Two "Build" = build. Else = pivot (change ICP / problem / price).
