Deal News | Dec 12, 2024 | Index Ventures

Cartesia, an AI startup founded by researchers from Stanford AI Lab, has raised $22 million in a funding round led by Index Ventures. The company aims to develop state-space models (SSMs), an innovative AI architecture that addresses the inefficiencies of traditional transformer models. SSMs offer heightened efficiency, better long-term memory, and the capability to operate in real-time on local devices, making AI more accessible and cost-effective. Cartesia's debut product, Sonic, is a text-to-speech model that showcases the potential of SSMs by providing high-quality, low-latency speech conversion. The technology boasts features such as local operation without internet and emotional controllability. The funding round also saw participation from A* Capital, Lightspeed, SV Angel, and numerous angel investors. Going forward, Cartesia aims to develop multimodal AI models capable of processing diverse inputs across a variety of applications, including healthcare, robotics, and gaming.
