For investment committees

Don't write the deal you'll write a post-mortem on.

Twelve canonical investor minds pressure-test your next investment across six rounds — and name the risks your IC won't catch until 24 months in.

Run a deal past the panel

Your first memo is on us.

Pick a deal you're about to commit to — the one your gut keeps circling back to at 11pm. ~8 minutes to the IC memo. The pre-mortem you can run before the IC has to write one.

AI fills what you didn't. Drop a deck and the brief writes itself — traction, financials, comps, even the priors a partner would raise. Because the signals you skip in the brief are the signals you'll find in the post-mortem.

Two passes. One yes.

Three real companies. The panel says no twice as often as yes — because most deals shouldn't get done. The point isn't the verdict. It's whether the room caught what your own would have, after the wire.

The panel

Twelve disagreeing minds. The partner you couldn't hire.

Each enters the room with a worldview and one thing they're looking for. They're not in your fund — so they don't owe you politeness. Half look for reasons to pass. The other half look for what the first half missed.

The richer the brief, the sharper the memo

What you don't say is what the post-mortem will.

The signals you skip in the brief are the signals you'll find in the post-mortem. Quality of brief × quality of panel = quality of memo. Not a slogan — a rule.

Thin brief

"lattice.com"

A readable memo. The obvious risks named. The non-obvious ones — the ones that show up in the post-mortem — left as your problem.

You get a useful artifact. You don't get the partner the room is missing.

the flap
Rich brief

URL + deck + three priors + the data room

Conviction named clearly. Trip-wires at 12 and 36 months. The pre-mortem your IC won't run because they don't have time. The argument the contrarian on your team would have made if they were brave enough.

Now the room is alive. Each lens has something to grip. The ripple lands on your desk.

What lands on your desk

The post-mortem you wish you'd had. Before you need it.

The polished memo opens with the call, the argument, the tripwire, and the next move. The debate, evidence archive, founder questions, and diligence agenda sit behind it as the audit trail.

i.

For the deals you walk away from.

The pre-mortem you can run before you commit. Trip-wires named in the memo, before they show up in the LP letter. The clean no, with the case attached.

ii.

For the deals you walk into.

The risks the panel surfaced become the terms you negotiate. The information asymmetry you bring to the table — anchored by the memo, defensible if challenged. Ammunition for the term sheet.

Pay only when the memo pack lands

Less than the deal you'd want to undo.

USD 29 gets the door open. Serious funds should treat this as a pre-IC ritual: three live deal checks, founder follow-up, source review, and a debrief before the next partner meeting.

It is remarkable how much long-term advantage people like us have gotten by trying to be consistently not stupid, instead of trying to be very intelligent.
