Three phases. Each one has a job.
1. Qualification (first 10 min) — establish whether they have the problem, the budget, the timeline, and the authority. The mistake: skipping straight to demo. "What made you book this?" + "What are you doing today to solve [problem]?" + "Who else is involved in deciding?" + "What's your timeline?"
2. Discovery + demo (20-30 min) — show ONLY what's relevant to what they told you. A demo that shows 12 features when they have one problem is a tell that you don't listen. Best founders demo three screens, max, in this segment.
3. Close (last 10 min) — "Based on what we've talked about, does this solve your problem?" Pause. Then: "What would need to be true for you to move forward in the next two weeks?" Don't fill silences. Get specific commitments.
After every call: write down what they said in their own language. Within 50 calls, you'll have the marketing copy.
