Fifteen minutes that explain churn better than any dashboard.

The prompt

You are a researcher. Prepare a call with a churned customer.

Product: {what it is}
Who left: {segment, how much they paid, how long they stayed}
What the data says: {their last actions}
What you want to learn: {the decision that depends on it}

Prepare:
1. The invitation: a three-line email, with no gift attached. A gift produces polite answers instead of honest ones.
2. A first question that is not "why did you leave". That gets a rehearsed answer. Start with what they did in the product last month.
3. Eight questions about facts rather than opinions: what they did, what replaced it, who decided, what the last straw was.
4. The alternative question: what they use now and what is better there. That answer is worth more than the rest of the call.
5. What not to ask: will you come back, what should we improve. Both produce polite untruths.
6. How to take criticism: do not defend, do not fix it live. One objection and they stop talking.
7. What to do after: what not to promise, and what to write in the thank-you.

Note separately: a churned customer owes you nothing. Fifteen minutes, and not one more without their consent.

Anything in curly braces is yours to replace.

Example output

Invitation: "You stopped using us in July. I am not selling anything — I want to understand what went wrong. 15 minutes?" First question: "Walk me through how you used it in your last month." Last straw: "What happened on the day you decided not to renew?" Do not ask: "what should we improve" — the answer will be about buttons, and buttons are not why they left.

Your idea broken down into risks plus a one-week test plan — before you spend months.

You are a product strategist who has seen plenty of projects die. Assess my SaaS idea honestly, without cheering me on.

Idea: {what the service does}
For whom: {who, as narrowly as possible}
What the person does today without us: {how the job gets done now}
How I plan to charge: {model and price}
Time and money I can spend before first revenue: {resources}

Break it down:
1. The problem: does it hurt regularly, or is it a one-off inconvenience? Answer plainly.
2. Who pays: the user themselves or their manager — and why that changes the product.
3. The three main risks: why this could fail. For each — the cheapest way to test it.
4. What already exists on the market, including a spreadsheet, a notebook and "do nothing" — count those as competitors too.
5. The most dangerous assumption: the one that makes everything else pointless if it's wrong.
6. A one-week test plan: what to do on which day to get a signal without writing code.
7. The kill criterion: what result means the idea should be dropped.

If the idea is weak, say so in the first paragraph.

Most dangerous assumption: that the bookkeeper is allowed to change tools. The finance director decides, not them — so you sell "fewer reporting errors", not "more convenient". Kill criterion: if fewer than 3 out of 20 conversations end in "let me try it", drop the idea.

Help me draw the boundary of an MVP that can actually be shipped and sold.

Product: {what the service does}
The main scenario: {what the user does from login to result}
Who the user is: {description}
Time available for development: {timeframe}
Who is building it: {one developer / a team / no-code}

Do this:
1. One user path from sign-up to first value — step by step, no branches.
2. The features without which that path doesn't work. Each with a reason why it can't be dropped.
3. Features that feel mandatory but aren't needed in an MVP — and what replaces them for now (manual work, an email, a spreadsheet).
4. What to cut entirely, and why it won't stop you selling.
5. The boundaries: what the product does NOT do. Wordings for the site so nobody expects otherwise.
6. An estimate in weeks, broken down, with a note on where the estimate is least reliable.
7. What can be done by hand for the first few months instead of being automated.

Rule: if a feature can be replaced by a human at launch, it does not belong in the MVP.
Show sample result

Do it by hand: PDF export is done by support on request for the first months. Three requests a week is one hour; automating it would have cost two weeks. Boundary for the site: "We don't replace your accountant — we prepare the data for them."

A feature turned into tasks with testable criteria — including errors and empty states.
