Our Story

Simsum was born from a simple belief: everyone deserves clothes that fit perfectly and express their unique style.

Founded by a physicist trained at top U.S. institutions, Simsum combines cutting-edge AI with the rich manufacturing heritage of the Greater Bay Area. We're not just building an app — we're reimagining how fashion works.

Our mission is to democratize fashion design by merging artificial intelligence with human creativity. By connecting consumers directly with skilled designers and manufacturers in Hong Kong and Guangdong, we eliminate waste and make custom clothing accessible to everyone.

Currently operating remotely as we build our MVP, we plan to establish our Hong Kong headquarters in 2026, cementing our position as an innovation hub bridging East and West.
