Founder Cold Email Scripts
Founder-to-Founder Template
"Hey [name], saw [Company] is doing [specific thing]. Built [product] for the same problem at my last company. 30-second loom showing how it works for [Company]: [link]. Worth a quick chat?"
Pain-Led Template
"Hi [name], most [ICP] we talk to are losing [X hours/week] to [problem]. Built [product] to fix it. Open to a 15-min call?"
Customer Reference Template
"Hi [name], [similar customer] saw [result] with our product. They mentioned [Company] might face similar challenges. Quick demo?"
Entrepreneur ICP Validation
Stage 1: Hypothesis
Define 3-5 specific ICP hypotheses based on initial assumptions.
Stage 2: Test
Send 200 emails to each hypothesis. Measure reply rate and meeting bookings.
Stage 3: Iterate
Cut bottom 50% performers. Double down on winners.
Stage 4: Scale
Single-segment focus delivers higher conversion. Generalize later.
Founder Productivity Tips
1. Reply Personally
Founder-handled replies convert 2-3x SDR-handled at this stage. You learn ICP fastest.
2. Calendar Discipline
Calendly link ready. Auto-booking saves time.
3. Volume Without Overwork
100 emails/day takes 30 minutes once dialed in. Don't burn out.
4. Document Everything
Track replies, objections, demo feedback. Builds ICP knowledge.
