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

Dimitro, a solo developer, turned a simple API product into a $12,000/month micro-SaaS business called Screenshot One. He did it not by inventing something new, but by leaning into his existing skill set, choosing a competitive niche with proven demand, and relentlessly talking to his customers. The conversation on Starter Story walks through the practical psychology behind his decisions: how he validates ideas, acquires customers without a big budget, and systematically reduces churn.

The Superpower Principle: Narrowing Your Idea Space

Before building anything, Dimitro faced a common problem: too many ideas. His solution was to impose a strict constraint based on his own strengths. As a backend developer, his "super skill" was building APIs. He therefore eliminated every idea that wasn't an API product. This wasn't about finding the most creative concept; it was about reducing his "space of ideas" to something he could build quickly and with high quality. He landed on Screenshot One—a tool that takes screenshots of websites via an API—partly because his alternative idea (an email validation API) felt "super boring" to him. The lesson is that personal interest and existing competence are powerful filters for choosing a project you can sustain long enough to make profitable.

Competitors as a Signal, Not a Threat
