System online · Stacy v1.13

We build the operating system
for a household.

Ghost Holding is a private engineering lab. We design Stacy — an autonomous AI operating system that runs documents, vendors, finances, the family calendar, and a home-lab fleet. Real agents, real automations, real infrastructure. Always on. Always private.

Autonomous agent

Meet Stacy.

Not a chatbot. Stacy is a resident agent inside the household — she owns an inbox, a phone number, a full Notion workspace, and the authority to act on small things without waiting for permission. She reports up. She doesn't ask down.

01

Tiered authority

Acts on reversible household matters under $50 unassisted. Escalates money, medical, and legal to the founder. Never guesses on the irreversible.

02

Multi-channel presence

Reachable by SMS, email, iPhone Shortcut, Stream Deck, iMessage bridge, or dashboard. She meets the household where it is — not the other way around.

03

Self-funding directive

Every real-money savings event goes to her Savings Ledger. Every operational cost goes to her Cost Ledger. Goal: monthly earn ≥ monthly cost for three consecutive months.

04

Passive observation lab

A second agent, Wilfred, reads the household's activity weekly and surfaces patterns, threshold crossings, and comedic juxtapositions. Only when they cross the bar.

Capabilities

What Stacy runs.

Six connected systems, one operator. Every write is auditable. Every escalation goes to a founder. No third-party training on household data — ever.

Document Vault

Every household paper — deeds, titles, medical records, receipts — filed, tagged, and retrievable by natural query. Compromised credentials tracked separately with rotation plans.

Vendor Directory

Every service provider, contractor, and account. Contact info, contract terms, last-touch, next-touch. Waiting-On database tracks every open commitment.

Financial Ledgers

Savings, Costs, Hopes & Dreams. Stacy proactively price-shops, forces price matches, cancels dead subscriptions, and negotiates bills — logging every dollar she moves.

Family Calendar

Kids' schedules, appointments, school events, family logistics. Cross-referenced with the Waiting-On DB so nothing quietly slips.

Home Lab

Tech inventory across every device — CPU, GPU, RAM, spare capacity. Before recommending a purchase, Stacy checks whether the fleet can already run it.

Secrets & Governance

Tokens, credentials, and API keys catalogued in a pointer table — never the raw values. Every decision is either reversible under Tier A, or escalated for approval.

Architecture

Built on the founder's stack.

Notion for durable state. Cloudflare for edge routing and Workers. Raspberry Pi cluster on Tailscale for private compute. Every component chosen for privacy, resilience, and audit-ability — not vendor lock-in.

└─ Notion (durable state)
└─ Cloudflare Pages + Workers (edge)
└─ Twilio (SMS channel)
└─ Gmail / Google Workspace (inbox)
└─ Tailscale mesh (private compute)
└─ Nomad Pi cluster (Tim, Ron, Wilfred)
└─ Keeper (sensitive credentials)

This is what we build.

Ghost Holding is a private lab, and Stacy runs one household — ours. But the architecture, the agent design, and the governance model are the real product. If you're a partner, an integrator, or you're just curious how a household gets its own operating system, get in touch.
