    AI will be everywhere, but needs to be way faster, process longer contexts and remember more before it's universal. Transformers won't get us there. Cartesia is building towards that future with pioneering architectures for AI Excited to announce our $27M seed :) Congrats Karan, Albert, Brandon, Arjun and team! It’s been amazing to see such an absolutely cracked team execute over the past months, thanks for letting me have a little sidecar seat :) Check out the blog and playground in the first comment.

    We've raised $27M from Index Ventures, Lightspeed, Factory, Conviction, SV Angel, General Catalyst, A*, Databricks and our wonderful angels. Cartesia Sonic is the fastest ultra-realistic voice model, and our audio models now power the next generation of voice agents, digital media, and assistants across startups and large enterprises. Our mission is to build real-time intelligence with long memory, that runs wherever you are. Multimodal brains for everyone!

    It's been a amazing to see our work on SSMs go from academia to powering real-time voice in production across thousands of customers. And excited to share a sneak peak into our research on multi-stream models for multimodal data. Grateful for our early team and supporters :)

    Co-founder @ Cartesia | Prev. Stanford ML PhD

    Excited to share our seed round on the journey to revolutionize interactive, multimodal intelligence. 🚀 ---- During my PhD, it was clear to me that I wanted to work on problems in ML that have a real-world impact on people. When we started Cartesia, we set out to reimagine the fundamental building blocks of machine learning to do just this — how do we build long-living intelligence that reasons and interacts with people and the world around us. This requires a paradigm shift in how we think about modeling — not just quality but also efficiency. Our work on state space models (SSMs) have enabled breakthroughs in building more efficient, scalable, and reasoning-capable AI systems that can tackle complex challenges across a wide array of applications. Some highlights from the past year - Built state-of-the-art, ultrafast audio models - Brought our models on-device to run directly on user devices (phones/laptops) - Grown to power thousands of production voice AI application It’s been incredibly fun building with such an amazing, hungry team of people with the best supporters. The journey is just beginning, and I couldn't be more excited about what's ahead. 💡

    The Brain Wave Collective's most recent tech deep dive was on Cartesia... and they just raised a seed?! 😯 I genuinely thought they were further along. This is some seriously cool TTS tech. The voices are incredible, and the UI and API are a delight to use. We've tapped this tech for recent projects including a hackathon we won last month. I've sent people voices for fun and they describe the results as "Magic" Fantastic technology. Congratulations Cartesia! You're going to go far.

    Congrats to the Cartesia team on announcing their seed (Karan Goel Albert Gu Brandon Yang Jacqueline Wibowo). And thanks for having me for the ride as an investor! I first met Karan Goel and Albert Gu back at Stanford University, where we were computer science PhD students together advised by Chris Re. An incredible team building the future of SSMs. Let's go!

    We’re excited to announce our investment in Cartesia, leading $27M in new funding to help them build the next generation of real-time AI models. While transformer models have revolutionized AI and power many of today’s applications, they come with clear limitations: they’re slow, computationally expensive, and often out of reach for all but the largest companies. Cartesia is changing that. Their pioneering state space models (SSMs) are shaping the next wave of innovation in AI, delivering faster inference, better scalability, and real-time performance, with the ability to run locally on any device. Their Sonic voice API is already delivering expressive, lifelike speech for hundreds of businesses, from startups to public companies. Led by an exceptional team of Stanford researchers, including Karan Goel, Albert Gu (one of TIME’s 100’s most influential people in AI), Arjun Desai, Brandon Yang, and their former professor Chris Ré, Cartesia’s SSMs will help developers build highly efficient AI applications across a wide range of industries like customer service, sales and marketing, robotics, healthcare, transportation, education, gaming, defense, security, and more. Watch below to learn more about Cartesia and our investment:

  • Excited to share that Quora is partnering with Cartesia to add audio capabilities to Poe! Users can already interact with advanced LLMs on Poe. Now they can also get audio responses in diverse voices and languages, transforming text into audio for a richer experience. Want to hear today's news in our vintage 1920's Radioman voice, or create epic stories narrated by our immersive Wizardman voice? You can do it all on Poe. "Poe brings together the world's best AI, all in one place. With Cartesia's Sonic model, users can interact with a wide range of high-quality, human-like voices in multiple languages, enhancing their experience on our platform," says Spencer Chan, Quora's Head of Poe Product.
