Rime

Rime is an enterprise conversational voice AI platform providing low-latency text-to-speech and voice-interaction models for customer-facing applications in regulated industries. It is built for contact-center, healthcare, fintech, and hospitality teams that need natural, compliance-grade spoken AI at production scale.

Rime, from San Francisco-based Rime Labs, builds text-to-speech and conversational voice models designed for real-time human conversation, offering three models: Coda (balanced quality and speed), Arcana (expressive multilingual voices), and Mist (real-time, low-latency). The platform provides 600+ voices across 50+ languages with regional dialects, sub-100ms time-to-first-byte latency in production, and controls over accent, pace, and tone, and is designed by linguists to prioritize natural speech rhythm and prosody. Rime supports cloud API, self-hosted/on-premises, and VPC deployment with SOC 2 Type II and HIPAA (BAA) compliance, targeting contact centers and regulated workflows such as appointment scheduling and revenue-cycle management. Founded in 2022 by Lily Clifford, Brooke Larson, and Ares Geovanos, Rime raised a $24M Series A led by M13 in July 2026 (with Twilio Ventures, Corazon Capital, Unusual Ventures, and Cadenza Ventures), bringing total funding to about $29.5M, and appointed former Meta audio lead Rafael Valle as Chief Scientist.
