I spent 25 years translating between languages, cultures, and legal systems. The job taught me one thing: Meaning is fragile. Context drifts. And when stakes are high, the only thing that survives is proof.

Now I build proof for AI.

SAT-CHAIN (Semantic Anchor Token with cryptographic chain of custody) is a cryptographic governance layer for regulated industries. When a regulator asks "Was this AI compliant?", most companies assert. We prove.

Four layers of deterministic enforcement:

→ Layer 1 - Prevention Governance rules auto-generated from regulatory requirements. Injected into the AI before generation. Violations blocked by design.

→ Layer 2 - Verification Post-generation validation: exact matching, semantic analysis, LLM judgment. Three tiers. No gaps.

→ Layer 3 - Relationship Governance The innovation others miss. A document can contain only true facts and still create a false impression. We verify the structure, catching unauthorized relationships between facts, not just the facts themselves.

→ Layer 4 - Action Governance For agentic AI. Seven-layer mediation with least-privilege enforcement. We control what the AI does, not just what it says.

Every interaction: SHA-256 hashed, digitally signed, appended to an immutable audit chain built for FDA, SEC, and FINRA inspection.

LLM Agnostic - one governance layer across any model, or multiple models working together

No Fine-Tuning - no model lock-in

Self-Extending - describe your compliance need in plain English, we generate the rules

Built for industries where "probably compliant" is professionally negligent.

SAT-CHAIN is the enforcement layer of a five-part system:

→ LISA Core — captures and translates your AI conversations into portable, machine-executable memory. Your context, your data, yours to own. Works across every major AI platform.

→ Inference Shield — protects what you publish. Detects IP leakage risk before public disclosure.

→ LISA DocCore — converts regulations into machine-executable governance rules. Regulation becomes enforcement, automatically.

→ SAT-CHAIN — enforces them. What AI says, provably governed.

From Probable to Provable.
