Documented cause
Readability, built by Arc90 as a clean-reading browser tool, pivoted in 2012 to a publisher micropayment platform where subscribers paid $5-$10/month to fund writers. The model collapsed because most publishers opted out of receiving payments, leaving funds unclaimed. By 2016 the service shut down, having failed to establish either side of its two-sided marketplace despite strong product adoption.
Lesson
“A two-sided payment marketplace requires active opt-in from both content creators and consumers simultaneously.”
