Use Bolt/Cursor to turn a pain point into an ugly MVP, price at the $99/mo + free-trial sweet spot, ship in 4 days — a repeatable pipeline that did $12K in month one.
Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
[Video] Sebastian Vulcus building an AI app solo in 4 days and making $12K in month one is just the hook — the heart of the video is a pattern drawn from data across 1,000+ micro-software businesses: 70% of founders make under $1,000/mo, and only 1-2% break $50K. The conclusion: once AI (Bolt.new/Cursor) lets anyone turn natural language into a working app, code stops being a competitive advantage and the contest moves to “user psychology + market economics.” The losers build whatever they personally think is cool and polish it behind closed doors for weeks before finding a customer; the top 30% do the reverse — they mine Reddit complaints, dig through three-star reviews on Product Hunt, or watch the repetitive grunt work in their own job, then use AI to quickly ship an ugly MVP that solves exactly one pain point.
