TraceZero
Zero Data Residue.
Strip PII and PHI from live audio and text streams before they touch downstream LLMs. Ephemeral, RAM-only execution on Swiss GPUs with synthetic neural voice re-generation. Zero disk persistence. Zero cross-border exposure.

Why residue matters
Why residue mattersSensitive streams cannot leave a trail.
Regulated Swiss organisations cannot send raw audio or text to external LLMs. Names, AHV numbers, diagnoses and voice identity must never persist — on disk or outside Switzerland.
is enough to trigger nDSG, FINMA or sector sanctions. Residue is the problem.
PII and PHI travel inside streams
Transcripts and voice packets carry names, identifiers and clinical detail straight into model context unless they are stripped first.
Cross-border transfer is a hard stop
Once data leaves Switzerland it falls under different legal regimes. Recovery and audit become nearly impossible.
Voice itself is biometric
Even after text redaction, the original speaker’s voice can re-identify the individual. Identity must be replaced, not only masked.
Pipeline
De-identify before the model ever sees the data.
TraceZero sits in front of your LLMs and agents. Everything that reaches them is already clean, ephemeral, and Swiss-bound.
Live stream in
Audio or text arrives over a secure channel. Frames are held only in RAM — never written to disk.
Swiss GPU · strip & resynthesize
PII and PHI are removed in real time. Speaker identity is replaced with a neural voice that preserves prosody.
Clean stream out
Only the de-identified stream continues to your LLM or agent. Original buffers are zero-filled immediately.
Architecture principles
Four guarantees built into the product.
Zero disk persistence
RAM-only buffers, zero-filled after every frame. No intermediate files, no residual audio, no recoverable traces on the host.
Swiss GPU execution
Sovereign inference inside ISO 27001 facilities in Zürich. Data never leaves Swiss jurisdiction.
Neural voice resynthesis
Speaker identity is replaced while prosody, emotion and timing are preserved — so the conversation still feels natural.
Zero cross-border exposure
All processing stays inside Switzerland. No US cloud, no EU transfer, no third-country sub-processors.
What leaves the room is already clean.
