Company information

The facts on file

Description
Cartesia is a voice AI vendor whose flagship text-to-speech model, Sonic-3.6, is a streaming TTS API producing expressive voices — including laughter — across 44 languages, built on State Space Models for low latency. The stack spans Sonic (TTS), Ink (speech-to-text) and Managed Agents (telephony-connected voice agents), and is aimed at developers and enterprise teams building real-time conversational agents rather than creators making one-off voiceovers. Vendor-named target sectors are financial services, healthcare and government, with deployment available in cloud, on-premise and on-device with in-region inference.

Markets
Developers, Startups, Enterprise, Financial services, Healthcare, Government
Integrations
Streaming TTS/STT API, Cartesia-provisioned telephony numbers, Cloud, on-premise and on-device deployment, SSO (Enterprise tier), Shared Slack channel (Enterprise tier)
Pricing
USD $5/month (Pro) — 100K credits, ~133 TTS minutes, commercial use licence and instant voice cloning · free tier: Free $0/mo: 20K credits/month, $1 prepaid agents/month, TTS + STT, ~27 TTS minutes, ~1h51m STT, 2 concurrent TTS requests; instant voice cloning excluded and no commercial use licence pricing page ↗
Regulatory
Commercial use licence begins at the Pro tier ($5/mo); the Free tier carries no commercial use licence. DPAs and BAAs, SSO and security questionnaire support are Enterprise-only. The pricing FAQ lists a heading for SOC 2 Type II but the answer was not retrieved, so SOC 2 status is unverified. A Trust Center (trust.cartesia.ai) and acceptable use policy are published but were not retrieved, so no claim is made about voice-cloning consent requirements.
