Founder & Entrepreneur
building delightful products
NYC-based Korean-Canadian entrepreneur building product-led SaaS tools, obsessed with great product experiences and lifelong learning. I work across product, design, growth, and operations to turn complex ideas into simple, high-impact solutions.
Started my first business at 14. Been building ever since.
Right now, I'm running Supademo - we help 150,000+ professionals create elegant, high-converting interactive product demos with AI. Profiably scaled to mid-7-figure ARR with a lean, capital efficient team. G2's #5 fastest growing product out of 125,912.
Before this, I built Coastline Market - North America's first demand-driven seafood marketplace. Scaled to 7-figure revenues, got into Techstars, made Forbes 30 Under 30 at 22. Then COVID hit, we lost 90% of revenue overnight, and pivoted to Freshline - B2B e-commerce for food distributors.
Outside of work: amateur athlete, big sports fan, foodie, always traveling somewhere new.
What I Do
Building products that scale, from zero to millions
Ship AI Products
I build AI features users actually use. Demo creation, instant translation, smart editing - practical AI that solves real problems.
Scale SaaS
I grow products profitably. Supademo: 4x YoY, mid-7-figure ARR, 150,000+ users. Bootstrapped, lean team, no VC.
Build in Public
I share the journey. GTM10 winner, G2 Leader 6 quarters running. Lessons from bootstrapping to market leader.
