# Voice AI startup Rime secures $24M Series A

> Rime, a voice AI startup, has raised 24 million dollars in a Series A led by M13 Ventures, with Twilio Ventures, Corazon Capital, and Unusual Ventures participating. The company builds conversational voice models aimed at the unglamorous but enormous world of enterprise phone calls, the customer-service and appointment lines that businesses field by the millions. The scale it already handles is the headline. Rime says its systems take part in more than 100 million calls a month across food service, healthcare, and airlines, with named customers including the Mayo Clinic and Dialpad. That volume matters, because voice AI lives or dies on reliability: a model that sounds natural in a demo but fumbles real callers is worse than useless. The founding team leans academic and industry-tested, with a Stanford PhD student, a former Amazon Alexa engineer, and a Stanford engineer, and it recently added Rafael Valle from Meta as chief scientist. In a field crowded with voice startups, Rime is betting that proven call volume and research depth are what separate a product from a demo.
