Brand is really the connection between you and your customersif you have a very strong culture, then the brand will come through.
Culture is simply a shared way of doing something with passion.
Having a clear mission and making sure you know that mission and making sure that mission comes through the company is probably the most important thing you can do for both culture and values.
[On culture] It's living the core values when you hire; when you write an email; when you are working on a project; when you are walking in the hall.
In organizations (or even in a society) where culture is weak, you need an abundance of heavy, precise rules and processes.
There's no such thing as a good or bad culture, it's either a strong or weak culture. And a good culture for somebody else may not be a good culture for you.
What I've been surprised by is not how different people are, but how similar they are. There are certain types of Airbnb people, and they are in every city in the world - it's just that in some cultures, there is more of a generational divide.
