A great presentation and separate post about a huge eCommerce business you probably haven’t heard of, founded only in 2015.
Its success is down to a team buying feature, social integration, gamification and live streaming.
These features have led to a daily active user (DAU) to monthly active user (MAU) ratio, a measure of engagement, of almost 50% – the highest, by some margin, among peers.
