The missed-call cost calculator is the right entry point. It makes the problem concrete before you pitch anything. Built this stack for real (roofing, HVAC) and the number that lands hardest in the calculator: average value per booked job. For roofers that’s $8,000-12,000. If they miss 3-4 calls a week and convert even 15% of those, the monthly revenue leak is visible before you say a single word about your product. One addition that increased demo conversion rate: show the ‘best case’ vs ‘current case’ side by side. Not just 'here’s what you’re losing' — but 'here’s what recovering 50% of those calls would add per year.' The prospect does the math themselves. Wren is sharp. The WebGL orb scrolling is a nice touch for a live demo.

@Vishal Chopde Once you add it — track which number closes it faster. In my builds, the revenue leak (missed calls × avg job value) lands harder than the conversion percentage. The client sees money they've already lost, not potential they might gain. Lost money is more visceral than future gains.
