Common Mistakes
Confusing a great product with a moat
A company can have a popular product today, but if there are no barriers to entry (e.g. low switching costs, easy duplication), competitors will quickly copy it and erode profits. A product is not a moat; a moat is a structural barrier.
📖 Real-World Example: A powerful switching cost moat
An enterprise software provider embeds its databases deep into the core operations of major banks. For a bank to switch to a competitor, it would require hundreds of millions of dollars, years of work, and the risk of operational downtime. These massive switching costs form a powerful moat, allowing the software firm to raise prices by 5% annually with near-zero customer churn.
