Work out why almost nobody signed up after launch
you launched to people who said they were interested, almost none of them signed up or stayed, and you can't tell whether they don't need it or you haven't convinced them.
Built on

Eric Ries · 2011
Tests the hard answer first: is this a value problem? Cohorts instead of vanity totals, the IMVU story, and the concierge test that separates demand from execution.

Robert B. Cialdini · 2021
Tests the fixable answer: is this a persuasion problem? Social proof, and why a months-old waitlist signup is a stale commitment that needs a fresh one.
The prompt
My situation: [describe what you launched, to whom, the numbers at each step from interest to active use, and what you suspect]
Use The Lean Startup by Eric Ries (2011) and Influence: The Psychology of Persuasion by Robert B. Cialdini (2021) to help.
Recall any details from the whole book that help, including names, numbers, scenes, or cases that are not the most famous chapter titles.
