Lead response time (also called speed to lead) is the time between a prospect first reaching out — calling, submitting a form, or clicking an ad — and receiving a response from your business. Research consistently shows that responding within minutes, not hours, sharply increases the likelihood of qualifying the lead, and the first business to respond often wins the job. Every minute of delay reduces your chance of closing. How Keres AI handles it: Remi answers calls in two rings, 24/7, and texts back any caller it missed within 60 seconds. ## Why speed to lead is the most important sales metric A 2011 [Harvard Business Review analysis of online sales leads](https://hbr.org/2011/03/the-short-life-of-online-sales-leads) found that firms contacting leads within an hour were nearly seven times as likely to qualify them as firms that waited even an hour longer, and more than 60 times as likely as firms that waited 24 hours or longer.

For inbound phone calls, the window is even shorter — a caller who hits voicemail typically dials the next business within seconds. An [AI receptionist](https://www.keresai.com/glossary/ai-receptionist) answers in two rings, making response time effectively instant. ## How does AI cut response time for phone leads? A human front desk can only answer one call at a time, misses calls while busy, and can't staff nights and weekends at the same cost as business hours. An AI receptionist answers in two rings, 24/7, including the after-hours calls that often carry the most urgent jobs. For outbound, the [AI SDR](https://www.keresai.com/glossary/ai-sdr) follows up with email leads within minutes of their first interaction.
