CLIENT
About the client

A "live commerce operator" creating a new market for live selling.

The client launched a "live commerce" platform business fusing live streaming with EC. They aimed for an interactive purchasing experience where operators introduce products in real time and viewers can buy on the spot while watching the stream.

The key to success is "Immersive live × on-the-spot buying flow × stable streaming infrastructure". Video, chat, purchase, promotion, and operations had to be designed as one, connecting viewers, operators, and the operations team in real time.
