SynthBoard

For teams

Walk into the meeting with
the call already argued out.

SynthBoard is built for the one person who carries the call — the founder, the lead, the operator. Named experts argue it first. You share the memo, with the dissent on the page, as a link anyone can read without an account.

Start freeSee how it works

Free to start. No card.

The memo your team opens

Why team calls go wrong

The room agrees too early.
The objection comes later.

  1. The first reasonable idea wins

    The room converges before anyone has argued the other side.

  2. The most senior voice wins

    People soften what they think once the boss has spoken.

  3. The dissent never gets said

    The objection comes up in a side thread, after the call is made.

Calls people bring before the meeting

From a pricing change
to a pre-mortem.

Three examples, written to show the shape of a run: the ask as it would be typed, how she reads it, who sits, and what comes back.

Usage pricing, or keep seats?

Work · Board of 3

We sell seats at $12 a user. Half our accounts are small teams that hammer the API. Move everyone to usage pricing in Q1, or keep seats and add an API tier? I bring the call to my co-founder on Thursday.

Chief of staff

Your board is seated: The CFO, The Customer, The Skeptic. They read the brief first, research alone, then react to one another.

  • The CustomerUser Voice
  • The SkepticRisk Assessor

The board’s call

Keep seats. Add a metered API tier above an included allowance, from February 1.

On your numbers, moving everyone to usage cuts revenue on the light half before the heavy half pays it back. A tier charges the accounts that drive the cost and leaves the rest alone.

Confidence58 · Moderate

The Customer disagreed

“Your small teams chose you for one simple price. A second meter on the invoice is a reason to look around.”

Three features, one sprint

Work · One expert

One sprint left this quarter. SSO for two enterprise trials, a Zapier integration 40 customers asked for, or fixing onboarding, where 30% drop off before the first project. Which one first?

Chief of staff

The Product Manager takes this: what each one is worth, to whom, and what the team should not start.

  • The Product ManagerProduct Manager

Asked first

Have the two trials said they won’t sign without SSO, or is it on their wish list?

They won’t sign without itWish listNot sure

The call · The Product Manager

Fix onboarding first. Schedule SSO for the next sprint, and only if a trial puts it in writing.

A 30% drop-off taxes every customer you will ever win, the two trials included. The Zapier asks are real, but none of the 40 said they would leave without it.

Why would the move upmarket fail?

Work · Board of 3

It is six months from now and our move upmarket failed. We hired two AEs and rebuilt pricing for 200-seat companies. Why did it fail, and what do we change before we start?

Chief of staff

A pre-mortem board: The Skeptic, The Sales Leader and The Operator. The Skeptic’s job is to argue against the plan.

  • The SkepticRisk Assessor
  • The Sales LeaderChief Revenue Officer
  • The OperatorCOO

The board’s call

Go upmarket, but sell to five design partners before you hire the second AE.

The likeliest failure is a sales cycle three times longer than your cash planned for. Five signed design partners prove the cycle and the price before the payroll does.

Confidence54 · Low

The Skeptic disagreed

“Your product has never passed a security review. The first 200-seat buyer will ask for one in week two.”

What you bring back

The call, the dissent,
and one link.

Experts on different models research alone, then react to one another. On a decision, two are assigned opposite sides.

The dissent, on the page.

Who disagreed, why, and what would change the call — kept on the memo, not smoothed away.

Every tool she reads

They ask before they answer.

When the answer turns on something only you know, the expert asks first. Tap a chip, or ask for their best guess.

Honest about it

Why the argument is real,
and what it is not.

The rules

Why the argument is real

  1. Every board is built to include someone whose job is to argue against the obvious answer.
  2. On a decision, at least two experts are assigned opposed positions.
  3. Seats are spread across model families, so the room is not one lab’s habits.
  4. Each expert researches alone, then reacts once to the others. When one changes position, the memo says so.
  5. Confidence drops with dissent. A board’s call is never rated above 90.
  6. The disagreement stays on the memo — who dissented, why, and what would change the call.
Today

What it is not, today

SynthBoard is not a shared team workspace. Each person has their own account, their own thread and their own file. What travels between you is the memo. Buying for a company? See what exists for a company.

  1. No shared workspace, no team admin, no pooled credits.
  2. No consensus number: the memo keeps the dissent instead.
  3. One account per person. The memo is what travels.

Who sits on a team’s call

Questions

Fair questions.
Straight answers.

What people ask before they bring a team’s call.

Or read the docs · get in touch

Can my whole team use one account?

No. Each person signs up with their own account, their own thread and what they keep on file. Share a board’s memo as a link; viewers need no account.

Is there a consensus score?

No. A board’s memo carries a confidence that drops when experts disagree and is never rated above 90, plus the dissent itself: who disagreed, why, and what would change the call. We think the dissent is more useful to a team than a score.

How does the memo reach the team?

A board’s memo shares as a page anyone can read without an account. Paste the link in the channel before the meeting, or export it as PDF or Markdown.

Can it read our tools?

She reads Notion, Google Docs, Gmail, Slack, Linear, HubSpot and more, and says what she read. A write is a preview you confirm. A tool is read-only until you allow writing, and writes are on Pro and above.

What does it cost?

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.
