Angel investing
without an IC, with an IC

Most angels make decisions alone, fast, on incomplete info. SynthBoard gives you an investment committee of named experts, arguing each deal before your wire goes out.

In short

Yes — early angels make the most expensive mistakes, and a board helps most before your pattern-matching is built. 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.

Angel Investors

Example · Board of 3

I have a $25K check ready. Strongest counter-argument before I send it?

Chief of staff

This one needs a board: The Investor, The Skeptic and The CFO. 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 on the new check.

Markups in 12 months without revenue typically reflect competitive deal heat, not company progress. Most pro-rata regret comes from anchoring to entry price, not current value.

Confidence64 · Moderate

The CFO disagreed

“If you have signaling weight (you led the prior round), passing could be read as concern. Communicate proactively”

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.

A company I invested in is raising again at 3x. Pro-rata, double down, or pass? — The Skeptic, up to 85 credits
I have 12 angel investments and 8 are stalled. Average down on one, write them off, or hold? — The CFO, up to 85 credits
A friend is raising a SAFE and I don't want to invest. How do I say no without burning the relationship? — The Empath, up to 85 credits

What you get

What she handles.
On this kind of call.

Solo-angel deal pressure-testing

No partner to argue with? The Skeptic, The Investor, and The Strategist run the IC discussion you don't have.

Check-sizing logic

How much to write into a SAFE you barely have access to? The Analyst and The CFO argue position size against your portfolio shape.

Follow-on and pro-rata decisions

When the company raises again, a board helps you decide: pro-rata, double down, or pass.

Founder evaluation framework

The Empath and The Investor pressure-test founder coachability, market timing, and execution probability.

Why SynthBoard

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

Built for the solo angel decision loop

Angels rarely have a sounding board. Your Chief of Staff is one, available the moment a SAFE hits your inbox — and talking to her is free within a daily allowance.

Anti-FOMO discipline

The Skeptic argues against deal heat, social proof, and "the round is closing" pressure — the three biggest angel decision distortions.

Portfolio-shape framing

Single-deal vibes are common; portfolio-shape analysis is rare. Tell her your existing positions once, and a board argues each new check in their context.

Private from founders and other angels

Some deals you can't pre-flag to anyone you know in the round. Your rooms are private to your account.

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.

The Investor

I’m not asking if it can work. I’m asking if it can get big, and what it’s worth if it can’t.

Best on: Raising, valuation, selling, or a job offer against your own company.
Won’t let you: Mistake a good small business for a fundable one, or the reverse.

In their words

Angels lose money in the second-best deal they couldn't say no to. The boardroom is the place to find out which deals belong in that bucket — before the wire goes out.

Questions

Fair questions.
Straight answers.

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

Is this useful if I've only made 2-3 angel investments?

Can this replace a deal-share community like AngelList?

No — AngelList provides deal flow and operational rails. SynthBoard provides decision rigor. Use both: AngelList for access, a board for conviction.

How does it handle deals where I have no access to the founder?

Many syndicate deals fit that profile. Use what you have: deck, market size, team backgrounds, terms. The board names the gaps (founder coachability, retention dynamics) and the questions to ask the lead investor.

Will the Boardroom argue against most deals?

It pressure-tests each deal honestly. For weak deals, yes — it argues against. For strong deals, it usually argues for, with specific watch-outs. The recommendation tracks the actual quality, not a default skepticism.

How current is it on angel-specific dynamics (SAFE terms, valuation caps)?

SAFEs (pre-money and post-money), valuation caps, MFN clauses, pro-rata rights, and common signaling traps are all in scope. For specific deal-term review, pair with your lawyer or a SAFE-savvy peer angel — the board is for strategic framing, not legal-grade term review.

Can I track my decisions over time?

Yes — every board leaves a memo: the call, the conditions, who disagreed and why. Your memos become your decision journal; review them once a year to sharpen your pattern-matching.

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.
