An audit of 13 real cases finds everyone who actually made money sold something that runs — a micro-tool or a proprietary dataset — not a course or playbook. Numbers are self-reported but striking: $32K MRR on $62/month infra, $41K from a single PDF, and finance as the niche with the highest willingness to pay. Reddit storytelling posts drove most distribution.
