Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
[Video] Sebastian Röhl, German, 32, a CS master's + 3 years of enterprise development. Quit in 2022 with "no idea at all, just 12 months of runway." What he built in the first 6 months got fewer than 12 downloads; when the 12-month deadline expired, he went back to his old employer and kept the side project going. In summer 2022 the HabitKit idea arrived; the MVP took 2 months to write. By the end of 2023: $3K MRR, and he quit a second time; by the end of 2024: $15K MRR, 300K+ downloads, 2,000+ ratings. He has long built in public on X, so the revenue can be cross-checked.
