Two books that specifically address your question with very different answers. Both books are completely worth your time reading. 1. The Innovation Stack: Building an Unbeatable Business One Crazy Idea at a Time by Jim McKelvey This is a founder of Square talking about how he survived Amazon entering the market with a copycat product. He also uses examples from other companies that survived competition using similar techniques. 2. 7 Powers: The Foundations of Business Strategy by Hamilton Helmer This book is a collection of 7 different types of “moats” that can exist. The authors claim (if I understood them correctly) that this list is exhaustive - there can only be these 7 types of moats to protect a business.
