The Challenge
Companies were struggling to scale outbound cold calling and inbound appointment scheduling due to the high cost of human call centers and inconsistent script adherence.
The Solution
Built autonomous Voice AI agents capable of holding fluid, ultra-low latency phone conversations. The agents interrupt naturally, handle complex objections, and sound indistinguishable from a human.
Design Process
Focused heavily on conversational latency (sub-500ms) and voice cloning to ensure trust. Designed dynamic branching logic to guide the AI back on script when prospects went off-topic.
Development Process
Integrated Vapi/BlandAI with Twilio for telecom routing. Connected the Voice AI directly to the client's CRM via custom webhooks so the AI could read live data (like available calendar slots) over the phone.
