AI Voice Agents

Speed to lead is the single most critical variable in modern B2B sales conversion. Research indicates that qualifying a prospective buyer within the first 5 minutes increases conversion rates by 391%.

1. The Death of the Manual Contact Form

When an interested buyer submits a contact form, they are in peak intent. Having a sales development representative (SDR) manually call them 4 hours later results in 70% voicemail drop rates.

2. Sub-800ms Voice Turn-Taking with Zendeet AI Voice

Zendeet's native integration with Zendeet AI Voice creates natural, human-sounding conversational voice agents that dial the prospect 60 seconds after form submission, answer product inquiries with grounded knowledge base citations, and book discovery meetings directly into rep calendars.
