Cartesia
Cartesia is a software development company based in San Francisco that develops real-time multimodal intelligence solutions designed to operate across various devices and platforms. The company was founded by a team of Stanford AI Lab researchers who specialized in state space models and foundation model development. Cartesia's mission is to create ubiquitous, interactive intelligence that functions seamlessly in diverse environments and use cases.
The company offers the Cartesia API, a comprehensive voice AI platform featuring state-of-the-art text-to-speech and speech-to-text models. Sonic is the company's flagship text-to-speech model, engineered for real-time and conversational applications with ultra-realistic audio output. Ink models provide streaming speech-to-text transcription optimized for voice applications, particularly in conversational AI scenarios. These solutions are purpose-built for developers creating voice agents, customer support systems, and interactive applications across multiple industries.
Cartesia has demonstrated significant market traction, powering millions of calls and serving tens of thousands of creators. The company has raised substantial funding, including a $64 million Series A led by Kleiner Perkins, bringing total funding to $91 million from investors including Index Ventures, Lightspeed, Dell Technologies Capital, and Samsung Ventures. With 72 employees and a growing user base, Cartesia continues to expand its platform capabilities to reduce computational costs and enable scalable AI deployment for its customers.
