You could almost hear the collective cheers from startup land when the news broke that Unilever was buying the five-year-old Dollar Shave Club for $1 billion. The Dollar Shave Club acquisition was an affirmation of a type of company-building that can be seen in everything from Airbnb to Warby Parker and Casper.

So beyond gross revenue, what is Dollar Shave Club doing that made it so valuable and that every company can learn from?
