Case Lab
For every "$10k/month" screenshot there's a course being sold. Case Lab does the opposite: we find a real solo-income play, check the evidence, and break down how it actually works — the niche, the system, the tool stack, and the honest gross-vs-net most headlines skip.
We review what exists. Anything we go on to try ourselves, we publish later — post-factum, with real numbers, including what didn't work. Analysis, not advice; found cases, not promises.
Senja.io hit $1M ARR (~$83k MRR, 3,000+ customers) with no funding and no employees rush — built in public over nearly four years. We break down the case: the niche, the build-in-public growth engine, the timeline, and the honest lesson it holds for solo builders.
A one-person Etsy print-on-demand shop has done ~$168.8k in lifetime sales since Oct 2022 (~$135k in 2024 alone), with detailed monthly income reports showing ~45% margins. We break down the case: the niche, the no-inventory model, the brutal Q4 seasonality, the tool stack, and the EU VAT trap most POD sellers walk straight into.
An operator built a 180-article content blog on Pinterest traffic, monetised it with display ads, then sold it for $13,000 — ~$25,500 total return over ~1.5 years. We break down the case: the niche, the build-and-flip model, the honest small-numbers read, and the tool stack.
Rob Percival, a Cambridge maths grad and ex-teacher, made one sale in his course's first 24 hours and went on to 2M+ students and reported revenue from >$2M to >$5M. We break down the case: the niche, the income model, the honest gross-vs-net, and why it quietly became a small team riding 2014 timing.
A 22-year-old runs five faceless AI YouTube channels generating roughly $40-60k/month — verified by Fortune from AdSense records. We break down the case: how it actually works, the tool stack, the honest gross-vs-net, and why most who copy it earn nothing.
