Fake-Stripe Pre-Sale: The Pieter Levels Pre-Order Smoke Test
The default smoke test captures email addresses. The Pieter Levels variant captures dollars instead - a real $1 refundable Stripe charge as the CTA, before the product exists.
This page is the companion writeup for that variant. Use it when an email-only signal isn’t strong enough to commit to a build.
Email signup vs $1 refundable charge
A waitlist captures curiosity (a free email costs the visitor nothing). A $1 charge captures a wallet decision. The same 100 visitors who would cheerfully give you an email might generate zero payment clicks - and that zero is the validated demand signal you actually need.
The conversion rate drops 3-5x compared to the email-only version. That is the point. The remaining converters are real demand, not curious clickers.
When to use this instead of email-only
- You ran the email-only smoke test and the signal was strong (>10% conversion); now you want to upgrade to dollar intent before you build.
- Your hypothesis price is high enough ($50+) that the wallet decision is a meaningful gate.
- You’re on your second or third hypothesis and need a sharper signal than email curiosity provides.
If you’re running your first ever smoke test, use the email-only version - it’s faster to set up, and the refund + FTC discipline below adds real overhead.
The setup (15 minutes)
The Stripe Payment Link mechanic is the same as in Chapter 1.5 (Price Your Hypothesis on the Smoke-Test Page) - read that for the full setup walkthrough. The variant-specific changes:
- CTA copy. Replace “Get on the waitlist” with “Reserve your spot ($1 today, refundable if we don’t ship by [date])”. The “$1 today” + “refundable” combination is the load-bearing phrase.
- Thank-you page. “You’re reserved. We’ll email you when we ship. Your $1 is fully refundable - just reply to this email and ask.”
- Footer disclosure. A one-line “About this pre-order: we are testing demand for [product]. If we don’t ship by [date], you get an automatic refund. Your $1 charge appears as JTHOUGHTS-RESERVE on your statement.”
- Stripe metadata. Set the product name to your hypothesis title + “(pre-order)”. This shows up on the customer’s bank statement and on the refund record.
Refund discipline (non-negotiable)
If the test fails (you don’t ship), you refund every $1 charge automatically within 30 days. Two reasons:
- Ethics. People gave you real money for a product that doesn’t exist. The refund is the implicit contract.
- FTC compliance. US FTC pre-order rules require you to ship within 30 days of the charge unless you disclose the delay in writing AND get the buyer’s consent. The blanket “refund if we don’t ship by [date]” disclosure on the landing page + thank-you page covers this for the smoke-test window.
Set a calendar reminder for Day 25 of the test window. If you haven’t started the build by then, log into Stripe and refund all charges in one batch (Dashboard > Payments > select all > Refund). Takes 5 minutes.
Reading the result (Levels’ 70-product tiers)
Based on Pieter Levels’ 70-product startups portfolio - a decade of running this exact test:
| Pre-sale count from a typical traffic spend | What it means | Next move |
|---|---|---|
| 0 sales | Hypothesis or price is wrong | Invalidate; rewrite the hypothesis sentence or the price point |
| 1-10 sales | Hypothesis directionally right; headline or audience wrong | Iterate headline + ad targeting; re-run for one more week |
| 50+ sales | Product-market-fit signal in range | Move to customer interviews and The One-Page Product Brief in parallel; start building |
What this test does NOT prove
The fake-pre-sale signal tells you the headline + price + audience combination converts at the moment of decision. It does NOT tell you:
- Whether the product will retain users once shipped (that’s Chapter 5.1, the Sean Ellis 40% test).
- Whether the unit economics work at full price (that’s a follow-on test post-launch).
- Whether the people who pre-ordered will actually use the product (that’s interview-stage research - Chapter 2.1, The Mom Test).
The pre-sale is the strongest pre-build demand signal you can buy. It is not validation that you have a business.
