For Founders

Run your hardest decisions through a boardroom you don't have yet.

Most founders are six months from PMF and six years from a real board of directors. SynthBoard puts 24 named experts one tap away to stress-test the calls that decide whether you survive.

Start free See how it works

In short

No — solo and pre-revenue is when SynthBoard pays off most. You have no co-founder to argue with, no advisors to ping, and the cost of a wrong call is 100% of your runway. 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.

An example

One ask, start to finish.
What comes back is a memo.

How a board takes a call like this: her read, who sits, what they ask first, then the call — with how sure they are, who disagreed and the first step.

Founders

Example · Board of 3

Should I take this acqui-hire offer or push to product-market fit?

Chief of staff

This one needs a board: The Strategist, The CFO and The Skeptic. The Strategist maps competitive dynamics and strategic options across multi-year horizons. Each researches alone first, then they react to one another — and on a decision, two of them take opposed sides.

Asked first

Has a competitor already made this move?

Yes, one hasNot that I knowWe’d be first

The board’s call

Negotiate to 55/45 with vesting acceleration on a defined milestone, not a clean accept or walk.

Equity split is rarely the actual disagreement — surface what each co-founder thinks is unfair. Anchor the negotiation to vesting + acceleration, not headline percentage.

Confidence64 · Moderate

The Skeptic disagreed

“A 60/40 split with no acceleration is worse than 50/50 with milestone-based catch-up”

First step Anchor the negotiation to vesting + acceleration, not headline percentage.this week

Other asks people bring here

Several asks in one message become several rooms, each with its expert and its own price on the card. Keep or drop any, then convene them together.

  • My co-founder wants 60/40 split — accept, negotiate, or walk? — The CFO, up to 85 credits
  • We can hire one of: senior engineer, founding designer, or first salesperson. Which? — The Skeptic, up to 85 credits
  • Is this fundraising round at $8M valuation a trap? — The Empath, up to 85 credits

What you get

What she handles.
On this kind of call.

A board, sized to the call

Bring the question to your Chief of Staff. She proposes who sits, and every board seats someone whose job is to argue against the obvious answer. There are no modes to pick; she sizes the room to the call.

Hold positions under pressure

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.

Carry the call forward

Your first move becomes a commitment with a date. What you decided stays on file, and it comes back when a new ask would reverse it.

Why SynthBoard

Why SynthBoard for this.
Not one voice. A board.

Honest, not flattering

The experts will tell you the equity ask is reasonable AND that your reluctance to grant it is the actual problem. The memo's confidence drops with dissent and is never above 90.

Priced on the card

Talking to your Chief of Staff is free within a daily allowance. A consult's card reads up to 85 credits; a board's card on the Free plan reads up to 135 credits. A board never bills above its card.

Faster than an advisor call

No scheduling, no recap, no waiting for a callback. The card shows the time before anything runs: about a minute for a consult, about 6–10 minutes for a board. You read the memo when it lands; nothing needs you to sit and watch.

Your world, on file

She keeps what you tell her on file, each fact with where it came from, and nothing is kept until you confirm it. Last quarter's pivot call is there when you bring her the hiring question.

Who sits

The experts for this call.
Each one holds a position.

Your Chief of Staff proposes who sits for the call, and every board is built with someone whose job is to argue against the obvious answer. Name an expert and they take a seat; tell her who you want on your board and they sit by default. How many seats a board has depends on your plan.

In their words

Founders bring me the question they want validated. I give them the question they should be asking instead. That's usually where the real decision is hiding.

Questions

Fair questions.
Straight answers.

What people ask before they bring this call to a board.

I'm solo and pre-revenue. Is SynthBoard too much?

No — solo and pre-revenue is when SynthBoard pays off most. You have no co-founder to argue with, no advisors to ping, and the cost of a wrong call is 100% of your runway. 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.

How is this different from asking ChatGPT?

ChatGPT gives you one perspective that tends to agree with however you framed the question. A SynthBoard board seats experts on different AI models; each researches alone, then reacts once, and the memo keeps the dissent — who disagreed and why. For decisions you can't un-make, that difference is the whole game.

Can I bring my actual advisors into a board?

Not into the room — the experts are AI, and a board belongs to your account. A board’s memo shares as a page anyone can read without an account. Run the board first, then send the memo to your real advisors to anchor the conversation.

Will it know my company context?

Yes, from what you tell her and what she reads. She keeps each fact on file with where it came from, and nothing is kept until you confirm it. She can read your tools — Linear, Stripe, Google Calendar, Notion and more — and says what she read.

What if the memo says something I disagree with?

Good. That's the design. Read the dissent — who disagreed, why, and what would change the call. If you still disagree, you now hold the strongest counter-arguments your investors, partners, or customers will raise. The call stays yours.

Is my data used to train models?

No. Your rooms, prompts, and memos are not used to train models, and they are encrypted at rest. What she keeps on file is yours to correct or wipe.
