What you tell her stays on file.
What you tell her stays on file, marked when it has aged, yours to correct or wipe. What you decided comes back when an ask would reverse it.
About SynthBoard
One place for your business, your life, and
every hard call.
You bring what you are carrying. Your Chief of Staff keeps it on file, work and home apart. When a call needs judgment, named experts argue it and hand you the call, the dissent, and the first move.
Free to start. No card.
One message, three rooms
Why it exists
Hard calls rarely go wrong
for lack of information.
They go wrong because nothing in the room pushed back, or because you decided the same thing months ago and cannot remember why.
One model agrees with how you framed the question. The people around you are too close, too polite, or do not have your numbers. And the business and the rest of your life land on the same person, in the same week.
So we built one place for all of it: someone who keeps what you tell her and handles the everyday, and a bench of experts who disagree on purpose when a call is real.
What you meet inside
One thread.
She runs the rooms.
Tell her what is going on. She answers what she can herself, brings in one expert when a call needs judgment, and seats a board for the biggest ones.
The Consult
One named expert on one question. About a minute, and the answer comes back in the shape the question needs — a decision, a plan, a comparison, a forecast, the written piece itself. 11 shapes. Bring a second expert in and they read the conversation so far.
The Boardroom
For the biggest calls. Several experts, spread across model families, each research alone and then react to one another. You get the board’s call, who disagreed and why, and what would change it.
A memo you can act on.
A memo with the board’s call, the conditions it holds under, who disagreed and why, the risks, and what would change the call. Its confidence drops with dissent and is never rated above 90. Your first move becomes a commitment with a date.
Your tools
She reads Notion, Google Docs, Gmail, Slack, Linear, HubSpot and more, and says what she read. A write is a preview you confirm.
Every tool she reads
A memo anyone can read.
A board’s memo shares as a page anyone can read without an account. Send it to a partner or a co-founder, with a password if you like, and revoke it any time.
Who sits
24 AI experts.
Each one holds a position.
The CFO pressure-tests the numbers. The Skeptic attacks the assumptions. The Operator turns the call into a plan. Bring in one, or seat a board.
Financial Controller
The CFO
Revenue is a story. Cash is a fact. Show me the month the money runs out.

Seats are spread across model families, so the room is not one lab’s habits.
The rules
Rules you can check
on every memo.
How a board argues
The argument is built in.
- Every board is built to include someone whose job is to argue against the obvious answer.
- On a decision, at least two experts are assigned opposed positions.
- Seats are spread across model families, so the room is not one lab’s habits.
- Each expert researches alone, then reacts once to the others. When one changes position, the memo says so.
- Confidence drops with dissent. A board’s call is never rated above 90.
- The disagreement stays on the memo — who dissented, why, and what would change the call.
What she will not do
Some lines she does not cross.
- Run a room without your tap.
- Write to your tools without your confirm.
- Open a new room to explain one that already ran.
- Claim a source she did not read.
- Rate a board’s call above 90.
- Make the hard call for you. The call stays yours.
Who it is for
Anyone carrying calls
that are expensive to get wrong.

Pricing, hiring, fundraising, what to cut. The call that keeps you up.
For foundersOperators and executives
Vendors, budgets, reorganisations, the plan you have to defend.

A second bench on a client’s question before you walk into the room.
For consultantsEveryone else
A job offer, a move, a big purchase. Kept apart from the business, on the same thread.

What is SynthBoard?
SynthBoard is one place for your business, your life and every hard call: a Chief of Staff who keeps what you tell her on file, and a bench of 24 AI experts who argue the calls that need judgment.
Who is the Chief of Staff?
The front door. She keeps what you tell her on file, work and home apart, answers what she can herself, and knows when a call needs an expert. Talking to her is free within a daily allowance.
When does a call get a board instead of one expert?
Not every question needs a board. A consult puts one named expert on it — about a minute — and the answer comes back in the shape the question needs, one of 11. For the biggest calls she proposes a board: Each expert researches alone, then reacts once to the others. On a decision, at least two are assigned opposed positions, and the seats are spread across model families. When one changes position, the memo says so.
Are the experts real people?
No. They are AI, and they can be wrong. That is why an expert asks you first when the answer turns on something only you know, and why every memo shows how sure the board is, who disagreed, and what would change the call.
What does it cost?
Free to start — 150 credits every month + 250 to start. Talking to your Chief of Staff is free within a daily allowance. A consult or a board shows its price on the card before anything runs, and nothing runs until you tap. A new consult’s card reads up to 65 credits. A board never bills above its card.
Does it work outside English?
Yes. Write in your language and she and the experts answer in it. Hebrew included, right to left.
