Almost every "validate your business idea" guide on the internet is secretly written for a very specific kind of founder: a 28-year-old software engineer raising a seed round in San Francisco. The frameworks assume you have venture money, a co-founder, eighteen months of runway, and a TAM you can spell.

That's not most founders. Most founders are a 41-year-old who wants to leave their job and open a coffee roastery. A nurse who has an idea for a service business. A consultant who's tired of being a consultant. They have one shot, their own savings, and a real family. Generic startup advice is not just unhelpful for them — it's actively dangerous.

You wouldn't buy a $30,000 car without a test drive. People quit their jobs for ideas they've never stress-tested for $0.

Below are 12 questions specifically designed for SMB and bootstrapped founders. They cost less than a sandwich. They take an evening. And they will save you, on average, somewhere between two years and your marriage.

How to use this

1. Set aside two uninterrupted hours.
2. Answer every question in writing. Out loud doesn't count.
3. Score each answer red / yellow / green using the rubric below.
4. Tally the colour mix at the end. Read the verdict.

The 12 brutal questions

Money (3 questions)

1. What does one unit cost you, fully loaded? Include your own time at a market rate. If you can't compute this in cash terms, that's a red.
2. What's the gap between that cost and what someone will actually pay? Not what you'd like them to pay — what a real person, asked today, would actually hand over.
3. How many units do you need to sell every month to cover your own household bills? If the number makes you laugh, that's a red.

Customer (3 questions)

4. Name three real people who will buy this from you in the first month. Not "people like X." Three names. With phone numbers.
5. What are those three people doing today instead? Their current solution is your real competitor — even if it's a spreadsheet, a friend, or just doing nothing.
6. Why would they switch to you, in their own words? Not your words. Theirs. If you can't quote one, you haven't asked.

Risk (3 questions)

7. What's the worst-case financial outcome, and can your household survive it? Not "we'll figure it out." A number, in cash, with a date.
8. What single regulator, contract, or platform could kill this overnight? Stripe, Apple, the FDA, your landlord, a single supplier. Name it. Then name your plan B.
9. What's the one legal document you don't have but should? Operating agreement, customer terms, IP assignment from your contractor, NDA with your supplier, employment contract.

You (3 questions)

10. What is the actual reason you want to do this? Status, freedom, money, escape, proving someone wrong? There's no right answer; only knowing the answer matters.
11. What part of the work do you secretly hope someone else will do? That's the part you'll be doing for the first two years, alone.
12. If this idea took ten years instead of two, would you still want to do it? Most real businesses do take ten years. This question separates a plan from a daydream.

The scoring rubric

• 🟢 Green — you have a clear, specific, evidenced answer.
• 🟡 Yellow — you have an answer but it's a guess.
• 🔴 Red — you don't have an answer, or the answer worries you.

The verdict

• 10–12 greens: stop reading. Go execute. You're rare.
• 7–9 greens: you have a real plan with known weaknesses. Go fix the yellows before you spend money.
• 4–6 greens: you have an idea, not a plan. Spend a month doing actual research before quitting anything.
• 0–3 greens: please, for the love of your savings account, do not quit your job yet.

What to do with the reds

Reds are not a verdict that the business is bad. They're a list of the experiments you actually need to run. Each red is a question you can usually answer in a week, often for free, by talking to real people. The founders who succeed are not the ones with no reds — they are the ones who systematically convert reds into greens before they're irreversibly committed.

The faster, more honest version

The hardest part of running this on yourself is, again, the honesty. You will instinctively round yellow up to green and red up to yellow. THE ROAST is built precisely for this moment: a tunable cast of advisors who will go through these questions with you and refuse to let you off easy. The Economist for the money questions. The Customer for the customer questions. The Lawyer and Operator for the risk questions. The Psychologist for the questions about you. Free to try, brutal on request.
