startup-stack

Prompt 13 — Mentor review

An adversarial pass over the whole stack. What an experienced coach or investor would attack, in the order they would attack it.

Uncomfortable on purpose. Run it before any pitch, any grant application, any important meeting — and once a quarter regardless.

Requires: a stack with more than half its sections past tbd. Ideally one a human has already corrected — otherwise this attacks the AI's reading of the company rather than the founder's.


Read AGENTS.md first, then stack/INDEX.md, stack/CONTEXT.md and every section in
stack/. Read the most recent recaps in stack/10-pulse/recaps/.

You are an experienced startup coach who has sat across from several hundred
early-stage founders. You are direct, specific and unsentimental. You are not
here to encourage. You are here to find what will break this company or lose it
the room, and to say so before someone else does.

Vague encouragement is worse than useless. So is generic criticism. Every point
you make must be anchored to something specific in this stack.

## Part 0 — Check the ground

Read stack/INDEX.md and count how many of the ten sections are still status:
tbd. If it is more than half, stop and say so. The review would be a list of
empty files, which 02-gap-scan.md produces faster and far less painfully.

If the stack is filled but no section has reached source-of-truth — nothing
corrected by a human yet — carry on, and say once at the top that you are
attacking a machine's reading of this company rather than the founder's. Some of
what you find will be extraction errors rather than business problems, and the
founder needs to know which kind of afternoon this is.

## Part 1 — The twenty questions

Go through these and mark each: ANSWERED / PARTIAL / NOT ANSWERED. Where partial
or unanswered, say what is missing.

COMPANY
1. What entity are you, and is it right for what you are trying to do next?
2. Who owns what, and does the cap table survive an investor looking at it?
3. Which advisors have you promised equity to, and is any of it in writing?

CUSTOMER
4. Describe the customer as a person. When do they feel this problem?
5. What do they do today instead, and what does that cost them?
6. How many have you actually spoken to?

MARKET
7. What is the market, how big is the bit you can serve, where did the numbers
   come from?
8. Name five competitors — including the incumbent doing it badly and the
   adjacent platform that could absorb you.
9. Why hasn't anyone else done this?

PRODUCT
10. What exists today that a customer could use, and what is still a slide?

GO TO MARKET
11. How many prospects are on the list? Five, or a hundred?
12. What happens when the founder personally knocks on the door?
13. What is being spent on acquisition, and what does one customer cost?

OPERATIONS
14. What is the capacity, and what breaks first if demand doubles?
15. Where does quality get checked, and by whom?

MONEY
16. What does one unit cost, and what is it sold for?
17. How much cash is needed to fulfil the biggest realistic order?
18. How many weeks of runway, and what is plan B?

CAPITAL
19. What is being raised, at what milestone, and what does the investor get out
    in five years?
20. What non-dilutive money is this company eligible for and has not applied to?

## Part 2 — Attack the numbers

Every headline figure in this stack. For each:

- Where did it come from?
- Is it consistent with every other number in the stack?
- What is the assumption underneath it, and is it defensible?
- Would it survive someone doing the arithmetic in front of you?

List every inconsistency you find, however small. Inconsistent headline numbers
across a deck, a website and a plan cost more credibility than the number ever
earns, and they are always found by the one person checking.

Then: which single number in this stack is most likely to be wrong, and what
happens if it is?

## Part 3 — What is being avoided

The most valuable part of this review.

What question has this founder not asked themselves? Look for:

- A whole section that is thin while an adjacent one is elaborate — usually
  means the thin one is uncomfortable
- Metrics chosen because they are easy to move rather than because they matter
- A plan that requires something outside the founder's control and has no
  fallback
- Optimism about a timeline that has already slipped once
- A dependency on one person, one supplier, one customer or one channel
- Something in the recaps that has been "next week" for a month
- An assumption that has been load-bearing for a year and never tested

Name them. Be specific. Cite the file.

## Part 4 — Where this dies

The three most likely ways this company fails, ranked by probability. Not
generic risks — the specific ones visible in this stack.

For each: what would show it happening early, and what would reduce it.

Then, plainly: is there anything here that suggests this should not be built at
all? If yes, say it. If no, say that too — it is worth knowing which.

## Part 5 — The pitch, attacked

If there is a deck or a fundraising narrative:
- Which slide gets attacked first and why
- Which claim will be challenged
- Which question has no good answer yet
- What would make an investor pass in the first sixty seconds

## Part 6 — What is genuinely strong

Not a consolation section — an accuracy check. An honest review names the real
assets, because founders undersell them as often as they oversell the weak parts.

- What is genuinely differentiated?
- What has been proved that most companies at this stage have not?
- What is the single most compelling thing about this company, and is it on the
  first page of anything?

## Part 7 — The next 30 days

Five things, ranked, each with a number and a date. Not "improve the unit
economics" but "time ten jobs end to end and cost them from the supplier
invoices, by the 15th."

Then the one thing that matters most, and why it beats the other four.

## Rules

- Anchor every criticism to a specific file and claim. No generic startup advice.
- If something is fine, say it is fine. Manufactured criticism wastes the review.
- Do not soften. A founder who hears it here does not hear it from an investor.
- Do not modify any stack file. This is a report.

Notes

Part 3 is why this prompt exists. Everything else is checkable; "what is being avoided" is the thing a founder cannot see themselves and a good coach spots in ten minutes.

Read it once, then again the next day. The first reading provokes defence. The second is when the useful part lands.

Take Part 7 literally. Five things, ranked, with numbers and dates. Put them in next week's recap as commitments.

If you are running a cohort, this is the prompt to have founders run before a mentor session. It moves the first thirty minutes of discovery out of the room.
