Shunsuke Nakagawa's profile on Product Hunt

About

I'm a 20-year-old engineering student in Tokyo, building consumer apps solo since I was 16. My previous project, Tripper (a travel itinerary tool), hit 1M+ views on TikTok before I moved on. Now I'm building Nudge AI — an AI auto-scheduler for students and freelancers who are too ADHD-shaped for Notion and too broke for Motion. I believe productivity tools shouldn't cost more than groceries. Building in public, shipping fast, learning out loud.
