The family office your household owns

Somebody has to hold the whole picture of your money. It shouldn't live only in your head.

An S corp, a partnership K-1, a rental LLC, maybe a trust or an equity grant, and a CPA you talk to twice a year. You're the only one who sees all of it. X1 holds the picture with you, files each fact under the entity it's connected to, and keeps it current from QuickBooks, your linked accounts, and the documents you already have. Your CPA, attorney, and advisor stay exactly who they are.

Free. No account, no call. Personal is $97 a month when you want X1 to keep holding the record.

Why X1 exists

See the whole structure. Then see what one decision touches.

Your CPA sees the return. Your attorney sees the agreement. You see everything, usually at 11pm. X1 holds the whole picture with you: it shows what's unresolved, lets you approve what gets shared, and keeps every answer with the records it touches.

Step 1 of 4: See the household before you isolate the issue.

01Connected context

See the household before you isolate the issue.

The S corp, the partnership, the rental, the trust, and what sits under each stay in one ownership picture.

Record types7Ownership paths2 into Harbor WorksOpen questionOne split to confirm

X1 doesn't flatten this into one unexplained total. The structure stays visible so each fact has somewhere honest to belong.

02Impact path

Trace one partnership from its owners to what depends on it.

Both ownership paths and the account, the policy, and the estimate below the business stay visible together.

Primary ownership path

Avery Design Co

60% recorded

Morgan Avery

40% to confirm

The operating account, the buy-sell policy, and the Q3 estimate stay in the trace. The question isn't isolated from the records that depend on its answer.

03Source-backed attention

See the mismatch and the documents behind it.

X1 separates what the paperwork supports from what still needs your decision.

Needs your decision

Confirm which split governs before X1 drafts the note to your CPA. Nothing changes in the record yet.

04Approved follow-through

Approve the next move, then keep the answer.

Your CPA receives only what you approve, and the answer comes back to the record.

You confirm the split

The record doesn't change until the decision is explicit.

Your CPA receives approved context

Nothing is shared until you confirm the recipient and the supporting documents.

X1 saves the answer with the affected records

The decision, both documents, the partnership, the account, the policy, and the estimate stay together.

Nothing moves until you say so. Then it moves in order.

Every week

X1 tells you what moved and drafts the next move. Nothing goes out until you say so.

One thing moved this week, and X1 already knows what it touches and who needs to hear about it. The note to your CPA is written. You read it, change a word if you want, and approve it. The reply gets filed with everything it affects. When nothing moved, X1 says that and leaves you alone.

Not sent

Hi Sam,

The 2025 K-1 for Harbor Works came in at 50/50, but the operating agreement still reads 60/40. Can you confirm which one governs the Q3 estimate before the 15th? Both documents are attached.

What stays with you

Your financial history shouldn't disappear when your professionals change.

Every move you approve leaves behind the documents it came from, what you decided, who handled it, and what happened. The next person helping you can pick up there instead of starting over.

The boundary

X1 never trades, never moves money, and never acts on its own. You and your professionals decide.

People and technology may change. Your household's history stays with you, with every decision and its reasons attached.

Built with advisors who coordinate complex families

“I'm building my virtual family office on X1. It's what I wished existed when I started advising families twenty years ago.”

Garrett Gunderson

Author of Killing Sacred Cows, founder of Wealth Factory

Garrett uses X1 with families whose tax, estate, insurance, and investment work crosses several professionals. X1 gives everyone the same starting point while the family decides what gets shared.

What one review looks like

The Avery household you traced above, carried through to an answer.

The situation
The operating agreement records Harbor Works LLC at 60% Avery Design Co and 40% Morgan Avery. The 2025 K-1 allocates the year 50/50, and the Q3 estimate is due on the 15th.
What X1 prepared
Both documents, the two ownership paths, and the account, the buy-sell policy, and the estimate that depend on the answer, with a drafted note to the CPA.
Who received it
The household's CPA, after you approved the packet.
What came back
The 60/40 governs and the K-1 gets amended. X1 recalculated nothing on its own; it filed the answer with the partnership, the account, the policy, and the estimate, so the next review starts there.
