Founders publish their own breakdowns: what they earned or lost, over what period, and what actually worked. We extract four things from such posts — the number, the period, the channel and the takeaway — and keep the link so every number can be re-read at the source. Failure is just as useful here: if three teams shut down for the same reason, that is knowledge normally bought with years.

Where the stories come from: founder communities on Reddit (r/startups, r/SaaS, r/SideProject, r/EntrepreneurRideAlong, r/Entrepreneur, r/indiehackers, r/productfails and others) through the official API, plus crowdfunding campaigns. Numbers are taken from the post text — what the author wrote themselves. We do not decode charts or screenshots, so this section only holds numbers you can re-read at the link; unverified ones are marked separately and never feed into idea scores.
