“When should a startup start working actively on defining its culture? Since I co-founded Reedsy in 2014, this question has always puzzled me: how can I define the culture of a company when it's just me and my co-founders? When is your culture starting to appear and then what should you do so it evolves positively? How do I make sure it's not all fake? Culture Decks Decoded is a great read for entrepreneurs who are not just looking at their top line revenue but also at the environment they're creating for their employees and the values they want to share with customers.”

“I really like the concept of this book, it's filled with lots of valuable insights. Having come from a company that screamed culture (for nearly 2 decades), I can fully understand why, how, where, when it's important. And, it’s a great reminder for me to continue to work with my team to define our culture. It's made me even more aware how important a strong culture is during the recruiting and hiring process, when giving feedback on performance and behaviour, as well as the dreaded exercise of firing.”

Julie Trell, Global Head (& Chief Human API)

“Culture becomes a defining feature of a company whether it’s done intentionally or not.  Success or failure can often be traced back to cultural values.  It’s such an important part of the businesses I have worked in or built that I wish I had read this years ago.  With the global digital revolution, never has placing emphasis on your company culture as a definable asset been more important than it is today.”
