Nuance Labs

Nuance Labs is an early-stage AI research company based in Seattle, Washington, building a human foundation model with emotional intelligence. It is developing a real-time, full-duplex audiovisual system that sees, hears, reasons, speaks, and expresses simultaneously, reading tone, facial expression, and hesitation to enable face-to-face AI interaction that feels human. Backed by Accel and Lightspeed Venture Partners, the company is pre-product: as of this enrichment pass it publishes only a marketing site (About, Press, Contact, Careers) with a "Get Demo" / early-access call to action, and exposes no public API, developer portal, documentation, SDKs, or other developer surface.

Nuance Labs is profiled on the APIs.io network. Tagged areas include Company, Ai, Artificial Intelligence, Foundation Model, and Emotional Intelligence.
