Nuance Labs raises $50M Series A to build real-time multimodal AI avatars, led by Lightspeed

Seattle startup Nuance Labs, founded by former Apple Vision Pro engineers, raised $50 million in a Series A led by Lightspeed to build a single end-to-end multimodal model that produces synchronized audio and visual AI avatar responses in real time. The firm aims to eliminate laggy, stuttering, and awkward nonverbal behavior in current avatars by ingesting audio and video together rather than chaining separate speech, language, and synthesis models.
