Project Overview

Built a sophisticated voice-based AI sales agent that automates the initial sales conversation process. The system can talk to users over calls, answer product questions, qualify leads, and automatically schedule demos using calendar integration.

The Problem

Initial sales conversations are repetitive and time-consuming for sales teams. Many potential customers have similar questions, and the process of qualifying leads and scheduling demos often involves multiple back-and-forth communications.
