Key Facts

• Calling an inbound lead within 5 minutes instead of 30 makes contact 100x more likely and qualification 21x more likely, according to Oldroyd's Lead Response Management Study.
• Firms that respond within an hour are nearly 7x more likely to qualify a lead than those waiting just one hour longer, per Harvard Business Review research on 1.25M leads.
• A 2011 HBR audit of 2,241 US companies found an average inbound lead response time of 42 hours, with 23% never responding at all.
• Only 37% of companies respond to inbound leads within one hour, while 24% take more than a day.
• Most response delays are systemic — sitting in routing and CRM configuration between lead creation and rep assignment — not in rep behavior, per Voiso's analysis.
• AI voice agents can respond to new leads in under 60 seconds, 24/7, closing the weekend gap vendors call a top lead-killer.
• Up to 50% of sales go to the vendor that responds first, a vendor-reported figure underscoring the first-responder advantage.
