Speed-to-lead calculator
Every minute a new lead waits, your odds of ever reaching them collapse. Put your own numbers in and see what slow response is costing you.
Why response speed matters this much
The research on lead response is brutal. The original Lead Response Management study found that a rep who calls within 5 minutes is roughly 21 times more likely to qualify a lead than one who waits 30 minutes, and about 100 times more likely to make contact than one who waits an hour. A Harvard Business Review audit of 2,241 US companies found the average B2B response time was 42 hours - while 78% of buyers purchase from the company that responds first.
How the math works
The calculator applies an engagement curve modeled on that research: the share of inbound leads you successfully engage drops from about 90% at sub-minute response to under 10% at next-day response. Your revenue loss is the gap between what you close at your current response time and what you would close responding in under a minute, at your close rate and deal size. It is an illustrative model, not a guarantee - but the direction and rough magnitude hold across industries.
How teams get to sub-minute response
Humans cannot sit on the form queue around the clock, but an AI phone agent can: it calls a new lead within seconds of form submission, qualifies with your questions, and books a meeting on your reps’ calendars. That is exactly what Harmony.ai’s Speed-to-Lead product does.
