Netflix kick started the online culture deck trend by posting their unique company culture deck online, as a means of communicating their culture to new and current employees, customers and partners.
I don't believe that Reed Hastings ever imagined how this 125 page document would resonate with the broader internet community - as of this writing this deck has been viewed over 17m times on Sildeshare and Sheryl Sandberg called it “probably the most important document ever to come out of the valley”. Apart from Netflix, there are culture decks by Hubspot, Hootsuite, Patreon, Asana, Soundstripe, Spotify, Valve and many more.
There is no simple formula for creating great company culture, and you definitely can't copy another company's culture, but you can learn from how other companies have created a meaningful and effective culture deck.
My first book Culture Decks Decoded is a handbook to help you write a culture deck for your company.
