blackbox — confidential compute. execution you can prove.

THE PROBLEM

Every prompt, every file, every embedding sits in plaintext on machines you don't control — one breach, one subpoena, one curious admin away from becoming someone else's data. Policies promise. They can't prove.

So we built the blackbox.

→ SEE THE SILICON

01 / THE SILICON

CPU + GPU.
One sealed enclave.

AMD SEV-SNP and NVIDIA H100 confidential computing, fused into a single attested boundary. Memory encrypted. The CPU ↔ GPU bus encrypted. Keys exist only inside measured code.

REMOTE ATTESTATION

02 / THE INFRASTRUCTURE

Zero-trust metal,
racked & attested.

Every node boots measured and proves what it runs before a single key is released. Workloads stay operator-blind end to end — signed responses, tamper-evident audit chains, policy enforced in silicon, not in a terms-of-service.

03 / THE PRODUCTS

One enclave. A whole product line.

Private Compute → Run jobs on data you're never allowed to see. Results out — nothing else. FOR · DEVELOPERS & DATA PARTNERSHIPS Verifier → Offline proof checks for every response — no trust in us required. FOR · AUDITORS & REGULATORS

04 / DEEP DIVE — RAG WORKSPACE

Your documents. Your model.
Nobody else.

Employees ask questions from the web UI or straight from their terminal. Documents are parsed, chunked and indexed entirely inside the enclave — and every answer carries a signed proof of what ran and what was retrieved.

05 / DEEP DIVE — INTERCEPTOR

Every agent
on a leash.

A fail-closed egress firewall under every AI agent on employee machines. Each binary reaches only the endpoints your signed policy allows — attributed by process hash, enforced in the kernel, no TLS interception. On any failure, traffic stops. Never the other way.

06 / DEEP DIVE — DATA ROOMS

Share the answer.
Never the file.

Sealed rooms for diligence, audits and deals. Counterparties ask questions inside the enclave and leave with signed answers and a tamper-evident audit chain — your documents never cross the boundary, and access dies the moment you revoke it.
