How I Built It: $12K/Month Micro SaaS | Starter Story

In 2023, Dimitro, a backend developer who had spent most of his career writing code for startups, reached $12,000 in monthly recurring revenue with a solo-built product called Screenshot One. He quit a job he describes as "the best job in the world" with a huge salary because he felt "something pushed me into another direction" — a childhood dream of building his own products. His path from employee to solopreneur is less about inspiration and more about a deliberate system for narrowing ideas, validating demand, and iterating on customer feedback.

Narrowing the Idea Space to a Super Skill

Dimitro started with "millions of ideas" but immediately applied a constraint: he would only build API products. As a server-side developer, building APIs was his super skill. This reduced his options to a manageable set. One idea was an email validation API, but it "looked super boring" to him. The other was a screenshot API. When he searched Google and saw "so many competitors," he took it as a positive signal. "Having some niche with competitors is good," he says. The real question is not whether competitors exist, but whether there are enough paying users to satisfy your goal — in his case, reaching $10,000 MRR. He argues that inventing something truly unique is extremely hard, and even if you do, you still have to prove people need it.
