How Sunbit scaled VIP-level service to millions of customers with Cresta AI

Sunbit's contact center was growing faster than their IVR could handle. By replacing their tree-based phone system with Cresta's AI voice agent and layering in real-time agent assist and 100% QA coverage, Sunbit contained 50% of interactions autonomously, cut routing time from 90 seconds to five, and drove average handle times down 10% — while customer satisfaction went up.
