How it works

Real ads. Real buyers. An honest ending.

Strangers see an ad, land on a product page, click Pay on a checkout with no card fields, and then learn the product isn't live. Their Pay click tells you what a buyer costs.

The four steps

Four screens. One honest signal.

  1. Example Meta feed ad for a fictional bookkeeping app called Tally.

    01

    The ad in the feed

    Real Meta ads with real creatives: three angles, two creatives each, often two price points. Strangers decide in a scroll whether your idea is worth a tap.

  2. Example landing page for Tally at €29 a month with a Buy now button.

    02

    The landing page

    A real-looking product page with one promise, one price and a Buy now button. The click shows who wants it at that price.

  3. Example checkout for Tally asking only for name, email and country, with a Pay button.

    03

    The checkout, no card fields

    Name, email, country and a Pay button. No card fields, ever. The Pay click is the purchase-intent signal and the basis of the CAC proxy.

  4. Example reveal page for Tally saying it isn't live yet and nothing was charged, with an unticked opt-in box.

    04

    The honest reveal

    The product isn't live yet, nothing was charged, no card data was taken. An unticked opt-in lets real buyers ask to hear about the launch.

Timeline

Live in under 7 days.

  1. Day 0We agree the go / iterate / kill thresholds with you before anything runs.
  2. Days 1–2We write 3 angles, build the landing pages, the checkout and the reveal, and set up consented tracking.
  3. Days 2–6Meta ads run: 3 angles × 2 creatives, often at 2 price points, on your ad budget.
  4. Day 7You get the CAC report: cost per purchase intent as a range, the winning angle and price, and the verdict.
