Building and launching alone

Answer in a slot, not all day, and read the questions for the feature they're asking for. Repeated questions are the best product research you'll get.

Ask named people for money for a thing that doesn't exist yet, with a date and a full refund if you miss it. Then open the payment account first, not last.

Run it through 7 questions in an hour, then ask 10 named people for money before you write any code. If nobody pays, you've saved a month.

Look for a room you've already been sitting in. The best niche is a group whose problems you've watched for years and who'd notice if you stopped posting.

7 days. If the smallest version that someone would pay for takes longer than a week, the idea is too big for one person to test.

Yes. Free users prove that people like free things. A price on day one tells you in a week what a free tier hides for a year.

Labour you can check, such as reading, sorting and drafting. Not judgement. Hand an agent the decisions and it returns the average of everybody else's.

One named slot per product, the same pages in the same order, and a line in the file each time. Mine is 2 hours on a Sunday for the biggest product.

A metric, a number, a date and an action, written before launch while you're still hopeful. It lets you stop a product calmly instead of watching it fade.

Warm to cold. The room where people know your name goes first, on day one, with your best post. Strangers come after, once they can see somebody cared.

7 questions, in an hour, before any code. They came out of 25 dead products, and most of those deaths needed no new question.

Talk to the people who signed up. Rewriting the landing page, adding features and relaunching are what everybody does instead, and none of them works.

The dullest one you already know, written on one card and changed only in January. A new product should never also be a new stack.
