If you don’t design your company culture yourself, someone else will do it for you (and you may not like what they come up with).
Your company culture is the personality of your company. It’s defined by everything your company does, offers, and says, and it exists whether you’ve crafted it yourself or let others do so on your behalf.
When you take steps to build the company culture you desire, it sends a powerful message to your employees and, by extension, to everyone who interacts with your business on a daily basis.
