How Alex Finn built a $300K app with Cursor | Starter Story

Alex Finn built an app called "Screenshot to Code" that now generates $300,000 in revenue — and he did it without writing a single line of code himself. Every line was generated by Cursor, an AI coding tool. The app itself is straightforward: it takes a screenshot of a user interface and converts it into front-end code (HTML, CSS, Tailwind, React, etc.). Finn launched it in three months, and on launch day he made $100,000 in the first 15 minutes and $200,000 in two hours. The episode is a detailed walkthrough of how he did it, from idea selection to execution to launch strategy.

Finding the right idea: solving your own pain

Finn did not set out to build a business. He was a product manager who wanted to speed up his own workflow. He frequently needed to convert screenshots of designs into code, and existing tools were slow or inaccurate. So he built a scrappy version for himself using Cursor. The key principle here: he was his own customer. He knew the pain intimately because he lived it. He did not do market research, competitor analysis, or customer interviews. He identified a problem he personally had, built a minimal solution, and only later realized it had broad appeal.
