My name is Joseph - I'm a 🇰🇷🇨🇦 founder who's been building since the age of 15. I LOVE building products from zero and I'm constantly trying to learn and grow my craft. Currently building Supademo, the fastest way to transform any workflow into an interactive demo using AI. We help 3000+ users replace screensharing, endless video edits, or lengthy support docs with intuitive click-through demos. Previously, I co-founded Coastline, North America's first demand-driven marketplace for seafood and Freshline, an e-commerce platform for food distributors. Over 6+ years of building, our team's work was recognized under Forbes 30 Under 30, Thiel Fellowship, and the Financial Times. My DMs are open for new connections :)
