Cartesia Managed Agents is a hosted voice-agent platform for enterprise conversations. Cartesia says it co-designed the voice models and agent runtime, combining speech, turn-taking, reasoning, tool calls, telephony, and knowledge bases. Agents can connect to backend APIs and CRMs, answer from document collections, and run personalized outbound call batches. Cartesia describes use cases including claims intake, patient scheduling, retail returns, and IT helpdesk calls. Its product page also describes browser-based test calls and review of call recordings, transcripts, and summaries.
