Built by someone who
kills his own ideas.
I'm Umut. I run Memselon ☁️ — a one-person shop shipping SaaS, Framer plugins and 3D heroes. Before ScanGap I built Heroes and Memselon Mockup, and I've killed three other ideas this year alone — each one would have taken six months to ship.
ScanGap is the tool I needed for myself: drop an idea, get the real picture of who's already there, decide in 60 seconds. Then either ship — or pivot to one of the three wedges in the report.
