Shortly after Amazon 's acquisition of online retailer Zappos became public, Zappos CEO Tony Hsieh sent an e-mail to all Zappos employees explaining the move and what it means for the company and all of them--the employees. The apparent candidness and clairty of Hsieh's communique seems telling. Zappos has become a customer favorite largely because of its service and open culture ( The Consumerist shares a couple of examples, here and here ). And Hsieh's writes that Amazon values Zappos for that reason: Our culture at Zappos is unique and always evolving and changing, because one of our core values is to Embrace and Drive Change. What happens to our culture is up to us, which has always been true. Just like before, we are in control of our destiny and how our culture evolves. A big part of the reason why Amazon is interested in us is because they recognize the value of our culture, our people, and our brand. Their desire is for us to continue to grow and develop our culture (and perhaps even a little bit of our culture may rub off on them). They are not looking to have their folks come in and run Zappos unless we ask them to. That being said, they have a lot of experience and expertise in a lot of areas, so we're very excited about the opportunities to tap into their knowledge, expertise, and resources, especially on the technology side. This is about making the Zappos brand, culture, and business even stronger than it is today. Seth Godin writes--in a short, sharp post--that the Zappos sale contains a key lesson on what creates real value in companies today. Godin says that "what matters is..." -A corporate culture that's not the same (and where great people choose to work) -A tight relationship with customers that give you permission to talk with them -A business model that's remarkable and worth talking about -A story that spreads -Leadership Read his post here .
