Build AI humans, built for scale
Speech, perception, rendering, and orchestration in one API. Enterprise-grade video agents for healthcare, sales, support, and beyond.
We manage the full pipeline.
Most teams stitch together a TTS vendor, a rendering vendor, and an orchestration layer. Sunesis runs all four as one system, so latency and quality stay consistent end to end.
Speech
Real-time synthesis & recognition, sub-200ms.
Perception
Reads expression, tone, and intent as you talk.
Rendering
Photoreal video avatars at 30fps, any resolution.
Orchestration
Memory, tools, and turn-taking, all in one session.
Three models. Every agent.
Each one is purpose-built for a single job, instead of one general model doing all three badly.
Sunesis Render
The most natural human rendering we've shipped — contextually accurate expressions, emotion, and movement, not a lip-synced mask.
Sunesis Perceive
Multi-modal perception that sees, hears, and understands in real time, so an agent reacts to how something is said, not just what.
Sunesis Turn
Governs turn-taking and pacing — the lowest-latency, most accurate barge-in and handoff logic across the platform.
Security is not a feature. It's the foundation.
Defense in depth, by default. Encryption everywhere, isolated tenancy, and continuous auditing — so you can deploy to regulated environments without compromise.
Encryption everywhere
TLS 1.3 in transit, AES-256 at rest. Per-tenant encryption keys available on enterprise.
Key management
Rotatable API keys, scoped permissions, and hardware-backed HSMs for signing operations.
Data residency
Pin storage and processing to US, EU, or APAC regions to meet your data-sovereignty requirements.
Audit logs
Every privileged action is logged and exportable to your SIEM in real time via webhook.
Penetration tested
Annual third-party pentests. Findings reported to customers under NDA on request.
Isolated tenancy
Private compute pools with network isolation, no shared inference infrastructure.

Your brand has a voice. Make it literal.
Fine-tune a private voice, avatar, or agent model on your own data. Served only from your tenancy, evaluated against your brand rubric, and owned by you.
Send samples
Provide 30 minutes of consented audio, video, or text in your brand voice. We handle cleaning and alignment.
We fine-tune
Our research team fine-tunes a private model on your data, evaluated against held-out samples for fidelity.
You iterate
Review outputs, request adjustments, and sign off. The model is yours alone — served from your tenancy.
Deploy privately
Your custom model is addressable only by your keys. We never train base models on your data.
