Retell AI

Retell AI builds an AI voice agent platform for automating phone interactions. Its software enables businesses to answer questions, schedule appointments and resolve issues over the phone through conversational AI, without requiring human agents on every call. The system is designed to handle real customer conversations on both inbound and outbound calls.

The platform covers the full lifecycle of an AI phone agent: building, testing, deploying and monitoring. It integrates with telephony providers such as Twilio and Vonage, and draws on work in speech and natural language understanding, dialogue management, and analytics and quality assurance tooling. Users can measure agent performance after deployment as well as configure the agents themselves.

The company addresses a problem of considerable volume: millions of customer calls each year require human agents to answer questions, schedule appointments and resolve issues. Its software is applied across customer support, lead qualification and sales, appointment booking and scheduling, dispatch services, and telecommunications and contact centres.
