Person Model infrastructure.

User-owned continuity for AI systems that need memory, consent, provenance, and task recovery across time.

Memory that leaves a trail.

A Person Model has to be inspectable. Sources, decisions, scope, and custody state should be visible enough to audit without exposing the whole private life behind them.

01
Memory receiptsSource, timestamp, scope, and route stay attached to the context they support.
02
Provenance surfacesThe system can show what changed, why it changed, and which evidence was used.
03
Custody tracesSensitive continuity should not disappear into vendor memory with no return path.

Not the person. The protected layer around their context.

A PM is the continuity layer that lets AI support someone as an individual without handing their memory to every model, app, vendor, or interface they touch.

A Person Model is not the person. It is a consent-governed continuity model representing context, preferences, boundaries, communication style, relationships, goals, tasks, and provenance across AI systems.

  • Grant, narrow, revoke, quarantine, or move access without surrendering identity to the tool.
  • Keep consent, custody, inspection, portability, and revocation as first-class infrastructure.
  • Keep private memory encrypted outside model weights, with receipts for what changed.
Person Model

The user-owned continuity layer between a person and the AI systems that assist them.

Cadence Continuity

AI memory and task recovery infrastructure for persistent agents, with consent gates, routing, receipts, and bounded runtime behavior.

Harmony Nexus

The operating company and lab building the protected continuity core, early pilots, and partner-facing experience layers.

Local custody. Cloud scale. Partner experiences.

The protected continuity core stays under custody. Cloud infrastructure handles burst compute, multimodal processing, evaluation, security testing, and deployment. Partners get governed experiences, not the dangerous core.

A local custody core connected to cloud-scale infrastructure and governed partner interfaces.

Local custody core

Where private continuity state, graph/vector memory, consent receipts, and sensitive development stay controlled.

  • Encrypted stores outside model weights
  • Consent and policy engine
  • Provenance and receipts
  • Task recovery state
  • Local-first execution

Cloud scale layer

Elastic AI infrastructure for evaluation, multimodal processing, embeddings, security runs, and partner demos.

  • Vertex AI and Gemini
  • Embeddings and retrieval tests
  • GPU / TPU burst compute
  • Audit, logging, backups
  • Security test environments

Experience rooms

Vertical surfaces built on the same continuity core, each with its own policies, risk level, and data boundaries.

  • Agent workflows
  • Creative studios
  • Care and accessibility
  • Companion systems
  • Enterprise memory

One protected core. Many rooms where forgetting breaks trust.

The same core can support different experience rooms with different policy layers, data scopes, and risk controls.

A protected continuity core branching into multiple bounded AI experience rooms.

Persistent AI agents

Task state, decision history, provenance, and safe return for assistants that keep working.

Creative studios

Project memory for music, writing, visual work, game worlds, and long-running collaboration.

Care and accessibility

Supportive continuity for reminders, routines, appointments, caregiver notes, and handoff summaries.

Professional memory

Private chief-of-staff continuity for founders, researchers, operators, and technical teams.

Games and characters

Continuity-aware NPCs and interactive characters with stable relationship state and bounded memory.

Security testing

Defense against prompt injection, memory poisoning, unsafe persistence, and unauthorized changes.

Wearables and voice

Hands-free AI experiences that retain context without surrendering custody to every device surface.

Managed companion rooms

Higher-risk companion systems can run as governed, age-gated feature layers with strict memory boundaries.

Scattered memory threads becoming a guided safe return path.

The system returns with the thread.

The failure mode of most AI experiences is amnesia. Person Model infrastructure is built for safe return: recover the task, preserve the boundary, and show the receipt.

Task recoveryOpen loops, prior decisions, blocked gates, and next safe actions survive model and interface changes.
Persistence safetyContinuity can pause, narrow, or quarantine when context becomes stale, corrupted, or outside consent.
Inspectable returnThe user can see why the system came back to a thread instead of trusting a hidden memory claim.

We have something real. Now it needs test runway.

The next constraint is infrastructure: enough hardware, power, workspace, cloud access, security review, legal/IP support, and pilot packaging to move from local proof into controlled demonstrations.

$250k

Bridge funding to harden the continuity stack, complete pilot packaging, and launch design-partner tests without giving away the protected core.

Protected labLocal AI workstation/server, storage, networking, UPS, power monitoring, and secure development capacity.
Cloud scaleVertex/Gemini testing, embeddings, multimodal processing, security simulations, and burst compute.
Security and IPPrompt-injection, memory-poisoning, intrusion, legal/IP, contracts, and pilot agreements.
RunwayPower, commercial workspace, product packaging, documentation, and partner-ready demos.

Memory should not become the next lock-in layer.

Harmony Nexus is looking for the first serious bridge partner: an angel or strategic backer who understands AI infrastructure, privacy, security, assistive technology, creative tools, companions, or the urgency of getting persistent AI memory right before unsafe defaults harden into the market.
