Welcome to part two of our dinner with the CEOs of One King’s Lane, Birchbox, Warby Parker, and Thrillist/Jack Threads.

This month, we are dissecting the ups and downs of the ecommerce 2.0 movement: Are the valuations too high? Are the fads sustainable? Are any of these companies $1 billion exit material?

We asked our dinner guests about all of the above over four courses at New York’s Felice. Eavesdrop on part two of the conversation as we discuss why ecommerce is still so hard despite all the short cuts people love to tout like social marketing, streamlined supply chains, and celebrity endorsements.

Go here to watch part one of our dinner about why ecommerce 2.0 is mostly not emanating from Silicon Valley.
