Free to start. No card needed.

A demo, from real runs. A founder asks whether to sell the company to a bigger competitor, with its term sheet attached. She starts a page for the matter beside the others, with what she gathered and each fact’s source. Three experts take it at once, each with a different job, and the board’s answer lands. After the founder leaves: her note on Home, a WhatsApp nudge, a reply the expert noticed in Gmail with the next step drafted, and the founder’s AI app reading the decision.

An answer

An answer you can use,
and the work behind it.

Most questions get a plain answer. The work shows up when the question has numbers, papers or a deadline.

I have to decide whether to keep Dan, our VP of Sales. After two quarters the pipeline is at 31% of plan, and his one-year cliff vests in January. Keep him, or let him go?

The Sales Leader

My read: let Dan go, unless this week's breakdown shows the miss came from things he didn't control and he raised it early. Don't let the January cliff make the call for you.

What 31% actually tells you

At 31% of plan you don't have a VP who's a bit behind. You have a business running at under a third of what you planned.

  • If The plan was built on assumptions that broke (product, budget, headcount) and Dan raised it early with a plan then Keep him, but on a written 60-day plan with pipeline targets by source and a hard check-in
  • If The plan was reasonable and the pipeline sources he owns (outbound, his reps) are the weak ones then Let him go this month

What decides it for you: Whether the miss sits in parts of the funnel Dan controls, and whether he saw it coming

A board for the hard ones

Several experts at once,

A board for the hard ones. Several experts at once, each with a different job: one runs your numbers, one plays the buyer, one reads the fine print. Where two find the same thing, you see both names.

Papers in, work out. Send a term sheet, a lease, an offer. The expert reads it, tells you what to push back on, and its dates and terms go into that matter’s file.

Halcyon-term-sheet.pdf“A bigger competitor, Halcyon, offered $2.4M for my company, Lumen Analytics. Their term sheet is attached. We have 140 paying accounts, revenue is up 40% this year, and we have 14 months of runway. Sell, or keep building? Bring a few experts on this at once.”

Finds the clauses in their term sheet that would hurt you

$720,000 of the headline price is contingent, so the real value can fall below $2.4M.

What the board says

Sell only if your annual recurring revenue is under $480,000; above $800,000 the offer is cheap and you should counter or keep building.

  • If ARR is under $480,000 then Sell, but negotiate the terms hard
  • If ARR is $480,000 to $800,000 then Counter or walk
  • If ARR is over $800,000 then Keep building or demand a much higher price

The reply, noticed

The Investor

Halcyon's board approved a bump to $2.8M with 80% cash upfront ($2.24M at close, $560K held back), 30-day exclusivity, and a decision deadline of November 14.

Next: Pull your current ARR number and your per-account cohort retention curve for the last 90 days.

Re: Halcyon term sheet

Thanks for moving it to the board. The $2.8M with 80% cash is closer. Before we commit, I need to clarify three things:

Saved in your Gmail Drafts. Nothing was sent.

Day one, and later

The same question,
answered for your company.

Asked on day one, with nothing on file, and again once it knew the company: the same expert, the same words.

With an empty file

“Can we afford to hire a second engineer this quarter?”

The CFO

I can't tell yet. Nothing on file shows your cash or burn. The test is simple, though: you can afford the second engineer if your runway after the hire is still at least 12 months, and closer to 18 if you'll need to raise money before revenue covers payroll.

With what it knows

“Can we afford to hire a second engineer this quarter?”

The CFO

Not yet, and not before 14 November. On money alone, your 14 months of runway can absorb a second engineer only if their fully loaded cost is under about a sixth of your current monthly burn. The bigger issue is that the Halcyon term sheet (their "Halcyon-term-sheet.pdf", p. 1) expires that day if you don't countersign, and that decision changes the answer.

Questions

Fair questions.
Straight answers.

What people ask before they bring SynthBoard something real.

Ask her after you sign upYour question waits in her box.

Read the docs · Get in touch

What is SynthBoard?

You bring what’s on your mind — a decision, a paper to sign, what to do next. The right AI expert answers, or several at once; they show what they checked, keep your papers and dates, and when you want, stay with it. The experts are AI — named roles, not people.

Who is it for?

Anyone with something real to work out, at home or at work: a lease, a job offer, a price rise, a family decision.

Is it free?

Free to start: the Free plan comes with a month of usage, plus a welcome bonus when you sign up. Every message uses a little of your month, and nothing starts until you tap.

How does usage work?

Plans are usage tiers: Pro is for weekly decisions, Max carries about 3× Pro’s usage and Ultra about 6× Pro’s usage. Nothing starts until you tap, and heavier work like a board tells you up front when it takes a big share of your month. Developers on the API see exact credits.

When do several experts work on it?

When you ask for more than one view, or name the experts you want. Each takes a different job — one runs your numbers, one plays the other side, one looks for what could go wrong — and where two find the same thing you see both names.

What if the experts are wrong?

They can be: they’re AI. They show what they checked and where it came from, say plainly when they’re not sure, and on legal, medical or money matters they help you prepare and tell you when to see a professional.

Is my data private?

Your conversations are private until you share them, and every table that holds them is locked to your account at the database. We don’t sell your data, card details never reach us, and you can delete your account and everything in it yourself.

Which languages?

The language you write in. Hebrew and English are fully supported, right to left included.

Can I use it from Claude, ChatGPT or Cursor?

Yes. Connect your AI app and it can ask your experts, with your say-so, within what you allow each day. The answers also land on your Home.

Can I change or cancel?

Yes, any time. Your plan runs to the end of the period you paid for.
