I shipped a productivity SaaS in 30 days as a solo dev — here's what AI actually changed (and what it didn't) In 2019, 23.7% of new startups had a solo founder. By mid-2025, that number was 36.3%. Something structural shifted — and I think I felt it firsthand. I spent six years building products at companies in Kyiv. I watched features that a single developer could ship in a day get stuck for months in approval chains. The average enterprise PR sits untouched for four days before anyone even looks at it — not because people are lazy, but because process overhead scales faster than teams do. And yet… products still shipped. Users still came. Revenue went up. The dysfunction was real — and somehow it didn't matter. That made it more frustrating, not less. I always wanted to build something of my own. The blocker wasn't ideas. It wasn't time. It was design. I'm a backend-first developer. I can architect systems, write clean TypeScript, ship reliable APIs. But I can't make things look good
