[ Example build — The Harrow Group ]

The Harrow Group could not answer “what do we own” without three days of work. They kept their accountants’ ledger and their custodian statements, and we built the family’s picture on top of both. Live in eight months.

The Harrow Group is an example, not a client. The firm and the numbers are made up. The shape of the problem, the parts of the engine, and the way a build runs are real.

[ № 01 — The situation ]

One spreadsheet, one person, three days

A family office does not fail loudly. It just quietly depends on one person who knows where everything is.

The balance sheet

A spreadsheet rebuilt every quarter

It is accurate on the day it is finished and slightly wrong every day after that. One person holds the whole structure together, and the family’s view of itself is only as current as their last free week.

The assets

Half of what they own is on no statement

Private holdings, three properties, art, a share of an operating business, and loans between family members. None of it arrives in a feed, so none of it was in any system.

The family

Three branches, one file

Everyone sees everything or nobody sees anything. So the CFO answers questions by email, with numbers pasted into the body of the message.

“Nobody can tell me what we own without three days of work.”

Principal, first scoping session
[ № 02 — The constraint ]

What they would not replace

The books belong to the accountants and the custodians. This build never tried to take them.

Stays exactly where it is

The ledger and the statements stay

The accountants keep the general ledger for the operating companies, and the custodians produce the statements. Both are the record for tax and audit, and both are checked by people who are not us. We read them, and we reconcile to them. We are building the family’s view, not replacing anybody’s books.

[ № 03 — The scoping sprint ]

What we learned first

Two sessions, a whiteboard, and the CFO’s spreadsheet, at our cost.

01

Ownership is the hard part, not valuation

One property is owned by a holding company, the holding company is owned by a trust, and two branches of the family share the trust. No tool they had could hold that shape, so the CFO held it.

02

The question is always “what do I own”, never “what is the total”

Family members want their own line through the structure. That is a look-through calculation across several layers, and it has to be right the first time or nobody trusts it again.

03

A private asset needs a history, not a number

A valuation with no date, no source and nobody who approved it is not usable at tax time. We had to build valuations as a record of events, not a cell in a sheet.

04

The documents were the missing half

The deed, the shareholder agreement and the loan note sat in a filing cabinet, disconnected from the asset they belong to. Half the three days was spent finding paper.

[ № 04 — The build ]

The family balance sheet

The structure, drawn. People, trusts, holding companies and partnerships, and what each one owns — including the assets that arrive on no statement. Ask what one family member owns and the system works down through the entities and answers. A liquidity calendar shows the capital calls and tax dates coming. Each document sits with the asset it belongs to, and each branch sees only its own side.

[ № 05 — The parts ]

What it was assembled from

The records, the documents and the permissions already existed. Harrow paid for the ownership maths.

In the engine

Client and household records

People, relationships and the entities behind them — trusts, holdcos and partnerships, not just names.

In the engine

The whole financial picture

Accounts, property, private holdings, loans and insurance, with owners and entities attached.

In the engine

Documents and reporting

The family’s own reporting pack, and a place for the deed to live with the asset.

In the engine

Permissions and audit history

Branch-by-branch access, and a record of every change to a valuation or a structure.

In the engine

Client portal and mobile

Where family members look, instead of emailing the CFO.

Built for them

Ownership look-through

The maths that answers “what do I own” through several layers of entities.

Built for them

Private asset valuations

Valuations as a history: date, source, method and who approved it.

Built for them

The liquidity calendar

Capital calls, tax instalments and premiums against the cash that has to cover them.

Five of the eight pieces already existed. Three were built for Harrow.

[ № 06 — The line ]

How it actually ran

The longest of the four builds, because the structure had to be right before anything else was worth doing.

01

A free scoping sprint

Two sessions with the CFO and the family’s lawyer. We drew the structure on a whiteboard, then put it into the system to see what broke.

3 weeks · Free
02

A prototype of the structure

Their real entities, loaded from the CFO’s spreadsheet and drawn as a graph you can click through.

Week 4
03

Monthly releases

Entities and ownership. Then private assets and valuations. Then documents. Then the family portal and per-branch access.

Months 1–7
04

Live

The quarterly rebuild stopped. The CFO now reviews a balance sheet instead of building one.

Month 8

What changed

The family noticed one thing first: they stopped waiting.

Where it goes next

A family office plans in decades. The platform has to be able to follow.

Up next

The next two releases

Already agreed and dated.

  • A portal and mobile app for the next generation
  • Estate and gifting scenarios run across the whole structure
  • Capital call reminders that reach the right entity’s signatory
The longer game

Bring more of the ledger in

Only where it earns its place.

  • Hold the operating companies’ detail themselves
  • The quarterly session with the accountants becomes a review, not a rebuild
  • Add a fourth branch, or a new trust, without adding a person
  • The accountants keep the statutory books either way
Or pause

Or stop, and keep the balance sheet

The build ends. The platform does not.

  • The balance sheet is live and the CFO runs it
  • Stop the build team, keep the engine licence
  • Feeds, tax rules and reporting stay current underneath
  • Come back for the estate work when the family is ready

You choose the direction each month. Nothing about this build makes the next decision for you.
