Builder's Brief

Issue 09 | August 31, 2026

The 3-line message that turns interest into a paying customer.

1. Charge Before It’s Ready

Buffer had a paying customer four days after launch.

Before that, Joel Gascoigne built two pages. The first explained what Buffer did. The second listed the plans and the prices. Clicking a plan took you to a note saying it was not ready yet, with a box for your email. By the end of this you will have a price, one person to send it to, and the message to send them.

The email box measured curiosity. The plan click measured something closer to intent.

Most of us never build the second page.

You demo at a club meeting. Four people say it's sick. Somebody asks if you're hiring. You walk back to Cary feeling validated, and you were: you confirmed that your product is free and that people like free things.

Y Combinator's guide to finding your first users has a line students tend to read straight past. Charge real money early.

Money is the only feedback with a cost attached. "I'd use this" costs nothing to say. Thirty dollars costs thirty dollars, and the person who hands it over will email you the day the thing breaks, which is the whole reason to have early customers.

Here is the ask. It is shorter than you expect.

"I'm building [X] for [Y]. It's $30 a month when it launches on October 15. I'll take you on at that price and set it up for you myself. Want in?"

Three answers can come back.

If they say yes, take the payment now with a Stripe link, then deliver the service by hand while you build the software. That manual work is the point, not a shortcut around it.

If they say, “yes, but not at that price,” ask what number works and what they are comparing you to. That answer maps your competition better than any survey you could run.

If they say no, ask what they already spend money on to deal with the problem. The budget exists somewhere, and finding it is the work.

Two rules keep this honest. Tell them exactly what they get and when it arrives, and refund without argument if you miss the date.

If you are building something where revenue is genuinely years away, hardware or a licensed technology out of a lab, run the same test in a different currency. Ask for a signed letter of intent or a paid pilot. A signature carries the weight of a payment.

The first twenty dollars you collect will teach you more than the next forty people who tell you they like it.

So pick the one person who has already told you they like what you're building, and send them a price today. One number, one date, one message. If they say yes, you have a customer. If they say no, you have a reason, and the reason is worth more than the compliment you got last week.

Charge before it's ready.
