What is Rime?
Rime develops voice AI models for enterprise customer calls. Its site describes "conversational voice models for enterprise," and the company focuses on two things that often break voice agents in production: getting pronunciation right, including names, brands, and addresses, and keeping latency low through speech-to-speech technology.
The models power support, sales, and marketing calls in industries such as food service, healthcare, airlines, and fintech. According to TechCrunch, Rime processes more than 100 million calls per month, with customers including Mayo Clinic, Dialpad, Upstart, and Asurion.
Rime was founded in 2022 in San Francisco by Lily Clifford, a former Stanford PhD student, Brooke Larson, an ex-Amazon Alexa engineer, and Ares Geovanos, a Stanford engineer. The company recently hired Rafael Valle, formerly at Meta and Nvidia, as chief scientist.
In July 2026 Rime raised a $24 million Series A led by M13 Ventures, with Twilio Ventures, Corazon Capital, Unusual Ventures, and existing investors participating, bringing total funding to $29.5 million. It is a fit for teams building voice agents that need natural-sounding, accurate speech at scale.
