As an organization grows, it is very important to communicate and share its culture with new employees. Startups in particular often experience very rapid growth and need to make sure they keep their core values intact. To do this, you must keep the following questions in mind:

1. Who are we?
2. What are we doing here?
3. Why do we do it better than anyone else?
4. What makes us special?
5. What do we value?

Make sure that all current employees know the answers and that there is a mechanism in place to educate new employees. Whether it is a meeting with a member of the executive team or a discussion with the local team members, be sure to discuss your culture openly and with the seriousness that it deserves.
