What happens when "O2O" commerce feeds back information not just online to offline, but offline back to online? In other words, digital doesn't just affect physical; it now goes in the other direction, too. And the completion of this virtuous loop isn't just the holy grail of advertising and marketing for retailers and others, but is a new phenomenon, argues a16z partner Connie Chan, that she fittingly dubs online to offline "2.0".

In this short talk -- originally delivered at Wall Street Journal's D.Live Asia conference April 2018 -- Chan shares examples and experiments from China, as well as product insights and mindset shifts, behind what it means to go from "mobile first" to mobile only -- where one's phone isn't just an access point, but an entry point... And where even physical spaces, not just sites, could be personalized to us.
