曾言 / Samuel Zeng

Product Director. Math PhD. I’ve spent 10+ years building consumer products at scale — ride-hailing in Latin America, short video in Brazil, flight booking across Europe and China.

I think in systems. Math trained me to find the simplest model that explains the most. Products are just models with users.

Now: CPO of Travix (Trip.com Group), leading AI-native flight booking in Europe
