Born in Stanford's AI lab and now worth $1.6 billion, Cresta listens to every call in a contact center and coaches humans in real time - while quietly building the AI agents meant to replace some of those calls entirely.
Infobip, PolyAI, Cresta, Botpress and a pack of rivals are pouring hundreds of millions into software that picks up the phone before a person can. Here is who is winning, who got bought, and what it means the next time you dial support.
Customer service is being rebuilt in the background, one conversation at a time. A wave of companies - Cognigy, Parloa, Cresta, UJET, Amazon Connect, Cisco's Webex Contact Center, 8x8 and Vonage - are turning the contact center from a cost you apologize for into software that answers the phone. This is the story of the quiet redesign: who is building it, what changed in 2025 and 2026, and why the hold music is finally getting shorter.
