Our mission is to build the next generation of AI: ubiquitous, interactive intelligence that runs wherever you are. Today, not even the best models can continuously process and reason over a year-long stream of audio, video and text - 1B text tokens, 10B audio tokens and 1T video tokens - let alone do this on-device.We're pioneering the model architectures that will make this possible. Our founding team met as PhDs at the Stanford AI Lab, where we invented State Space Models or SSMs, a new primitive for training large-scale foundation models. Our team combines deep expertise in model innovation and systems engineering paired with a design-minded product engineering team to build and ship cutting edge models and experiences. We bring commercial experience from companies like Scale AI, Doordash, Microsoft, Google Brain, Snorkel, Zoom, Character AI, and more.Our first model is Sonic, the fastest model that allows you to generate ultra-realistic and expressive voices from text. After just months of development, Sonic tops every reputable third party evaluation platform as the best model in the space, standing out on its latency, naturalness, and fine-grained controllability features like speed and emotion. Sonic is widely adopted across real time uses cases like call centers, gaming, avatars, and entertainment. We're funded by leading investors at Index Ventures and Lightspeed Venture Partners, along with Factory, Conviction, A Star, General Catalyst, SV Angel, Databricks, and others. We're fortunate to have the support of many amazing advisors, and 90+ angels across many industries, including the world's foremost experts in AI.
