About Rime

Rime is a Series A voice AI company on a mission to make voice interactions feel more human. Drawing on deep expertise in linguistics and machine learning, Rime builds and deploys frontier voice models—positioning itself as analogous to OpenAI or Anthropic but specialized in the voice and speech space. The company delivers its models through a flexible cloud-hosted API or fully on-premises deployments, integrating seamlessly with customers' existing orchestration stacks and agent scaffolding. Rime serves product and engineering teams at companies like Decagon and Cresta, operating on a usage-based pricing model. Based in San Francisco with a small, autonomous team, Rime is scaling rapidly and currently managing more customer demand than capacity.
