About

We build the voice, character, and conversation layer for AI.

Sunesis Labs helps teams build digital characters they can see and talk to in real time, powered by natural voice, lifelike video, and production-ready conversational AI.

Our mission

Every AI today can read text. Almost none can talk. We're closing that gap, building the infrastructure so any developer can create a digital character that listens, understands, and responds the way a person would, in real time, at production scale.

What we believe

Principles, not slogans.

Voice first

Voice is the most human interface. We build for the moment someone forgets they're talking to a machine.

Sub-200ms or it doesn't ship

Latency is the difference between a conversation and a voicemail. We measure every millisecond.

Open by default

REST, streaming, SDKs in the languages you actually use. No vendor lock-in, ever.

Built for production

SOC 2 Type II, HIPAA-ready, 99.99% uptime. The boring stuff that makes it real.

What we build

One layer, three senses.

Voice

Natural, low-latency speech synthesis and cloning in 30+ languages.

Video

Lifelike digital characters that speak, react, and hold a gaze in real time.

Conversation

Production-ready agents that listen, reason, and respond like a person.

How we work

Build the future of conversation.
