The document discusses how to create a company culture that employees love. It argues that culture is more than just perks and rewards - it is a bar for what is possible at the company, a way to attract talent, and a promise to customers. The author explains that HubSpot's culture is rooted in transparency and autonomy. Most companies go wrong by not discussing culture until employees start or not giving employees a way to provide feedback. The author recommends talking about culture early and often during onboarding, making it a central focus, and providing a way for all employees to give feedback. HubSpot focuses on culture as a business priority, uses stories to reinforce it, shares information, is transparent, and iterates on the employee experience.
