Today's AI models are slow, expensive, and lack the depth of human intelligence. Their high computational costs mean only the largest companies can afford to develop and deploy them. "The next generation of AI requires a phase shift in how we think about model architectures and machine learning," says Karan Goel, co-founder and CEO of Cartesia. For centuries, human voices have carried the weight of communication, from intimate conversations to speeches that shaped history. But as technology advances, the way we engage with voice itself is undergoing a transformation that companies like Cartesia are determined to push forward.
Cartesia, a real-time AI-driven voice technology company, has secured $64 million in a Series A funding round led by Kleiner Perkins. The funding, also backed by Index Ventures, Lightspeed, A*Capital, Factory, Greycroft, Dell Technologies Capital, and Samsung Ventures, brings the startup’s total investment to $91 million. With over 10,000 customers already leveraging its technology, including Quora, Cresta, and Rasa, Cartesia is poised to shape the future of voice AI.
We've raised a $64M Series A led by @kleinerperkins to build the platform for real-time voice AI.
We'll use this funding to expand our team, and to build the next generation of models, infrastructure, and products for voice, starting with Sonic 2.0, available today.
