Summary:

  • Cartesia raised $64 million in Series A funding led by Kleiner Perkins.

  • Founded in 2023, Cartesia is a voice AI startup from Stanford’s AI Lab.

  • Sonic, their latest audio model, has cut latency from 90 to 45 milliseconds.

  • The startup aims to tackle core inefficiencies in modern AI technology.

  • Goel predicts that voice will become a crucial medium for future communication.

The Legacy Behind Cartesia

Since 1897, Karan Goel’s family has been at the forefront of manufacturing, starting from lab equipment to now venturing into the realm of voice AI. Growing up near his family’s factory, Goel was immersed in an entrepreneurial environment that shaped his future.

The Birth of Cartesia

Cartesia, co-founded by Goel in 2023, emerged from Stanford’s AI Lab with a vision to create real-time generative AI models focused on voice technology. The founding team includes notable researchers like Chris Ré, a prominent figure in AI.

Significant Funding Round

Recently, Cartesia raised $64 million in Series A funding led by Kleiner Perkins. This round saw participation from major players like Index Ventures, Lightspeed, and Samsung Ventures, bringing the total funding to $91 million. The startup is already serving over 10,000 customers, including brands like Quora and Cresta.

Innovations in Voice AI

Cartesia’s latest model, Sonic, has significantly reduced latency from 90 to 45 milliseconds, addressing core inefficiencies in AI technology. The focus is on enabling customers to utilize AI effectively as they scale, with diverse applications ranging from customer support to digital avatars.

The Future of Communication

Goel emphasizes the importance of voice as a communication medium, predicting it will be integral in interacting with businesses and technology.

The Art and Science of Voice AI

Cartesia’s name pays homage to René Descartes, reflecting the mathematical precision that drives their innovations. The challenge lies in creating voices that sound human without crossing into the uncanny valley—a delicate balance of authenticity and technology.

AI and Goel’s great-great-grandfather’s factory may seem worlds apart, yet both are built on the foundations of precision, innovation, and the collaborative spirit of the people behind them.
