ISpeedToLead achieves sub-5-minute lead response and 20–30 AI-booked demos weekly with Retell AI

The problem

ISpeedToLead's advertising campaigns generate seller leads 24/7, but human SDRs couldn't cover nights, weekends, and holidays — leaving high-intent contacts untouched due to shift gaps, demo overload, and timezone constraints.

First attempt

Before Retell AI, coverage dropped dramatically outside business hours and when SDRs were mid-demo, and scaling manually would have required hiring 10–20 additional reps — an increasingly unrealistic path.

Demo scheduling for high-value leads
output
“For higher-value sellers, the agent texts a Calendly link, and walks them through scheduling a live demo with the sales team”
5
Multi-channel follow-up sync
integration
“Calls, texts, and emails are now fully synced across systems”
6
Re-contact on no-answer
routing
“Leads who don't pick up the first AI call are recontacted through another channel automatically”
Reported outcome

Lead response time dropped to under 5 minutes around the clock, AI now books 20–30 qualified demos weekly, and ISpeedToLead scaled without hiring additional reps.
