For when your AI needs to be cross-examined
In law, insurance, finance and health, what an AI system knew, when, and who it showed it to will one day be asked in earnest: by a client, a regulator, or a court. Yohanun is the memory layer built to answer. Walls that hold no matter what anyone types, a person in the loop exactly where you draw the line, and a record that can be produced and stood behind.
Enterprise-grade AI infrastructure
Purpose-built for organizations that need AI systems with institutional memory, regulatory compliance, and explainable decision-making.
Clearance-Walled Memory
Labeled memory behind a platform-owned clearance ledger: matters, classification levels, personal ownership, and conflict-of-interest walls, enforced inside the retrieval query.
Audit by Architecture
Every gated read, every mandate decision, every escalation lands in an append-only ledger: who asked, under which authority, what was returned or allowed.
Bounded Agents
Mandates give every agent an explicit line: act freely below it, escalate to a human decision queue above it. Commits fail closed: no mandate, no silent action.
Built for regulated industries
Regulated industries don't need AI that promises to behave. They need AI whose boundaries they can demonstrate to an auditor.
Yohanun's architecture is built for exactly that demonstration: deterministic access enforcement, ledger-based grants and revocations, and a per-read audit trail. We don't claim certifications we don't hold; we show your compliance team the enforcement path itself.

The Governance API, Live
# Grant a matter clearance (conflict-checked)
POST /api/access/clearances/grant-matter
{ "principal_id": "associate_7",
"matter": "matter_a" }
# → 409 CONFLICT if an ethical wall blocks it
# Revoke: effective on the next request
POST /api/access/clearances/revoke-matter
{ "principal_id": "associate_7",
"matter": "matter_a" }
# Bound an agent's actions
POST /api/access/authorize-action
{ "action": "issue_refund", "amount": 4800 }
# → { "decision": "escalate",
# "escalation_id": "esc_91…" }
# A human decides the escalation

Your Cloud
The full Docker Compose stack in your own VPC, on any provider that runs Docker.
On-Premises
Fully inside your data center. Privileged data never crosses your perimeter.
Enterprise support & services
Dedicated support, custom integrations, and professional services to ensure successful AI deployment.
How Support Actually Works
Direct to the builder
We're a deliberately small company. Enterprise customers don't get a ticket queue; they get a direct line to the engineering that built the platform. That's not a tier; it's the only way we work.
Onboarding as partnership
Early enterprise deployments are design partnerships: we help model your matters, clearances, and mandates, and your requirements directly shape the roadmap.
SLAs by agreement
Response and availability commitments are set per contract, honestly, based on what we can genuinely deliver at our size, not marketing-page numbers.
Professional Services
Implementation
Architecture design, deployment planning, and technical implementation guidance.
Custom Development
Bespoke integrations, custom rules engines, and specialized compliance modules.
Training & Enablement
Team training, best practices, and semantic AI architecture workshops.
Ongoing Optimization
Performance tuning, rule optimization, and memory architecture enhancement.
