Why everyone gets fake door tests wrong

Jacob Dutton · Future Foundry Free Intermediate

Waitlists and fake door landing pages are prone to false positives, and this essay names exactly how: broad, outcome-selling copy pulls in people who click because it sounds interesting, not because they have the problem. It walks through a real case where 2,847 signups drove a funding decision, then only 3% converted at launch. It is a good starting point for anyone tempted to treat a fat signup list as proof, because it shows how to design the test so the number means something.

• Big signup totals from a generic fake door or waitlist are often false confidence: people opt in because the promise sounds appealing, not because they will buy.
• A cautionary case: 2,847 signups justified a build, but launch conversion was only 3%, because the test optimized for volume instead of qualification.
• Add qualification questions and immediate post-signup interviews, and measure engagement depth, so you are filtering for genuine prospects rather than counting curious clicks.
