Hey, I'm Tony.

Yu Shengnan

Developer and startup growth marketer based in Shanghai. I build tools at the intersection of AI, data, and distribution. Currently learning and building in public — shipping fast, writing about what works. Dad to a little girl who keeps things in perspective.

Shipping AI-powered tools for content discovery and growth. Obsessed with finding signal in noise — what makes a post go viral, which small creators are about to break out, and how to spot trends before they peak.

When I'm not building, I'm probably at the park with my daughter.
