Thesis is a place where people pay a solo founder monthly, suggest one experiment for them to run, and read what happened — good or bad. This is one of those results. How it works.
A launch-day post keeps sign-ups high for a month
What they expected: A launch post keeps sign-ups above 40 a week for four weeks.

Checked against an export from the founder's own product database, read line by line against the counting rule agreed before the run. Not against screenshots or the copy that shipped — the pilot does not host those yet, which is why this is the middle badge and not the strongest one.
A launch post and a follow-up thread a week later, both written by the founder rather than scheduled from a template, plus replies to every comment for the first 48 hours. No paid amplification, so what the post did on its own is what was measured.
Written down before it ran, alongside the claim it was meant to test. The pilot does not yet host screenshots or the copy that shipped — until it does, this is the whole description, and it is thinner than it should be for judging craft.
Weekly sign-ups compared against the eight weeks before. The launch-week jump did not last, and the four-week average is inside the normal week-to-week wobble. Attributed under the agreed methodology.
