A voice AI agent that handles 60% of inbound calls
Voice agent built on OpenAI Realtime + custom routing logic. Handles appointment booking, FAQs, and escalation to humans.
The challenge
Hearthline came to us with a clear problem: the existing system was slow, manual, and not scaling with growth.
Our approach
Two-week discovery sprint, four-week build with weekly production deploys, followed by four weeks of tuning and observability work.
The outcome
60% of calls fully handled, 58% cost reduction. The system now runs with minimal oversight and has headroom for 3× current load.
