For Investors

Run the partner meeting
before the partner meeting.

You can't convene the full IC every time a deal moves. SynthBoard puts a board on every thesis, diligence call, and portfolio decision — the memo lands in about 6–10 minutes, not five days.

In short

Yes. Your rooms are private to your account, encrypted at rest, and not used to train models. Nothing is shared unless you share a memo. For deeply sensitive deals, use code names; the analysis still holds.

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.

Investors

Example · Board of 3

Is this seed-stage AI infra deal at $25M post a fair valuation or a hype tax?

Chief of staff

This one needs a board: The Investor, The Strategist and The Skeptic. The Investor thinks like a board, an LP, and a downstream acquirer at once. Each researches alone first, then they react to one another — and on a decision, two of them take opposed sides.

Asked first

Are you after the biggest outcome, or the most certain one?

The biggestThe most certainNot sure

The board’s call

Pass at $25M but offer at $18M with a clear note on what would change the answer.

The market sizing model assumes a 2027 inflection that isn't supported by current spend signals. Founder fit is strong but the technical moat is thinner than the deck implies.

Confidence58 · Moderate

The Skeptic disagreed

“If the round closes anyway at $25M, you may regret passing — model the regret cost”

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.

Should we lead this round or follow at this stage? — The Strategist, up to 85 credits
My portfolio company wants to pivot from B2C to B2B — should I back it or push to stay? — The Skeptic, up to 85 credits
How do I structure the term sheet to protect against a soft Series A in 18 months? — The Data Scientist, up to 85 credits

What you get

What she handles.
On this kind of call.

Pressure-test investment theses

Bring your deal memo to a board. The Investor, The Skeptic, and The Futurist challenge the market sizing, founder fit, and exit assumptions before your real IC does.

Pre-mortem portfolio calls

Before doubling down on a struggling portfolio company, run the pre-mortem. What does failure look like in 6 months? The Boardroom surfaces the risks the founder is too close to see.

Map competitive landscapes faster

Each expert researches alone before reacting, so a board gets you from "interesting space" to a credible point of view fast. Bring it to the partner meeting with the dissent already mapped.

Why SynthBoard

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

An IC, on demand

You can't pull partners away every time you need a second read. A board gives you the argument without the calendar coordination.

Sycophancy is fatal in investing

A "yes" model would have made you write every YC-batch B2B SaaS check in 2021. The Boardroom argues with you because that's what makes returns.

Builds your decision history

Every board leaves a memo, and your thesis stays on file with its source. A past call comes back when a new deal would reverse it.

Priced on the card

Pro's monthly credits come to ≈ 18 full boards or 29 consults a month, for $20. Every board shows its price before it runs, and a board never bills above its card.

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.

Investors who win don't avoid being wrong. They avoid being wrong for predictable reasons. The Boardroom is the cheapest way to find the predictable reasons before you wire.

Questions

Fair questions.
Straight answers.

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

Can I run my deal memo past a board without leaking it?

How does this compare to deal-flow tools like Affinity or Harmonic?

Different layer entirely. Affinity and Harmonic give you sourcing and CRM. SynthBoard gives you the analysis — what to do with a deal once it's in your pipeline. Pair them.

Which mode works best for diligence?

There are no modes to pick; she sizes the room to the call. For diligence, ask for a board. On a decision, at least two experts are assigned opposed positions. The dissent is what makes an IC memo better.

Can I share a memo with LPs or co-investors?

Yes. A board’s memo shares as a page anyone can read without an account. It is read-only — a fair "show your work" appendix to an LP update.

Will it know my fund's thesis?

Once you tell her. Your thesis, stage, sector, and check size stay on file with their sources, and they ride into every room.

SynthBoard (synthboard.ai) is one place for your business, your life, and every hard call. Your Chief of Staff keeps what you tell her on file, and 24 named experts on different AI models take the calls — one expert for a consult, a board with opposed seats for the hard ones — and hand back a memo with the call, the dissent and the first move. How it works.
