THE FAMILY OFFICE SYSTEM OF RECORD
Preserve what you’ve built. Prepare those who carry it forward.
Your family's private operating system for wealth, entities, documents, decisions, and the people entrusted to carry them forward.
BUILT FROM A WORKING PRIVATE FAMILY-OFFICE SYSTEM · NOW IN PRIVATE PREVIEW
Steward what you’ve been entrusted with. Carry it forward.
The hardest part of family wealth is not the assets. It is the context around them: what exists, why it is structured that way, and what has to happen next. ArkLegacy exists so that context survives handoffs, advisors, and generations.
01 · THE PROBLEM
The most sophisticated thing you own is run out of inboxes.
A family with an operating company doesn’t have a portfolio problem. It has a coordination problem: the business, the estate, the accounts, the insurance, and five advisors, each holding a piece, none holding the whole.
The company
lives in the accounting file and the controller's head.
The estate
lives in a PDF the attorney sent in 2019.
The accounts
live behind eleven logins at four institutions.
The insurance
lives in a folder, renewed by autopay, read by no one.
The decisions
live in an email thread the spouse was cc'd on once.
The context
lives in one person's memory. That's the plan.
So the family becomes the integration layer: forwarding statements, re-explaining context, hoping nothing falls between the CPA and the attorney. It mostly works, until the one week it has to work perfectly.
02 · THE FAMILY MAP
One living picture of everything the family owns.
The Family Map draws the household, trusts, operating company, LLCs, property, accounts, and debt as one structure, not a list. Every node carries its value, its valuation basis, and the age of the document behind it. When evidence goes stale, the map says so before it matters.

03 · THE OPERATING LOOP
One loop, run every week, on the record.
ArkLegacy runs the same quiet discipline a good family office runs: notice what changed, understand what it means, hand it to one owner, prove it with a document, and record the decision.
01
What changed
Statements, closes, notices, and filings land on the map as changes - dated, valued, and tied to their source documents.
02
What it means
A change either informs or demands a decision. The ones that demand one are separated from the noise and framed with context.
03
Who owns it
Every open item has one owner - CPA, attorney, CFO, advisor, or family - and a due date the whole team can see.
04
What proves it
Numbers carry their evidence: the statement, appraisal, or agreement behind them, with its age and verification status.
05
Done, on record
Completion is recorded with who, when, and what document closed it - a decision record the family keeps forever.

04 · WHAT IT HOLDS
The system of record, owned by the family.
Every asset. Every entity. Every decision. One enduring record.
Family balance sheet
Private-company ownership, property, public accounts, and debt in one reconciled statement.
Holdings, broadly
Private equity, real estate, liquidity tiers, alternatives, and crypto - each valued with a stated basis.
Continuity readiness
Beneficiaries, trustees, signers, and the emergency package - scored, with the gaps named.
Decisions on record
Scenarios framed with evidence, and a permanent record of what was decided and why.
Family and advisor roles
The principal owns the record; spouse, next generation, and advisors see exactly what they are granted.
Action and approval queue
Open items with owners, deadlines, status history - and approvals that wait for a human.
A chief of staff that shows its work
The weekly briefing reads like a good chief of staff wrote it: what changed, what it means, what needs you. Every claim cites its source document; anything unverified says so plainly.
Concentration is the standing fact of this balance sheet: the 90% Meridian Fabrication stake is 60.4% of gross assets, carried at the December valuation.
05 · TRUST, STATED PLAINLY
Designed like it holds a family’s whole financial life. Because it will.
These are requirements the product is built to and work in progress, stated as such, never as certificates. Connections can read; nothing in the product can trade, transfer, or move money.
Human approval for consequential actions
Anything that would move money, change records, or contact an institution stops and waits for a person.
PRODUCT REQUIREMENTSource-linked answers
The AI must show which document supports each claim, and say so when confidence is low. No citation, no claim.
PRODUCT REQUIREMENTNo training on family data
Family records are context for answering the family's questions - not training material.
PRODUCT REQUIREMENTRole-scoped access
Each family member and advisor sees a defined slice. Granting and revoking is explicit and logged.
PRODUCT REQUIREMENTTenant isolation
Productizing the single-family system into strict per-family isolation is the core of the current engineering phase.
IN BUILDEncryption and audit trail
Encryption in transit and at rest, and an append-only audit trail on every consequential action, as the platform ships.

Honest status: the connector foundation is built and fixture-tested server-side. Turning any provider live requires real credentials, authentication, and per-family isolation, none of which the public demo has or pretends to have. The demo’s Connection Center runs every flow against labeled sandbox data instead.
