A competitive advantage is a specific reason customers choose you over the alternatives, which competitors cannot copy quickly. It shows up in a number: lower cost per unit, faster delivery, a higher price accepted. Being better or more passionate is not an advantage, because a competitor can claim the same thing tomorrow.
Test any claimed advantage with one question. What would a competitor have to do to match it, and how long would that take? If the answer is hiring two people or copying your landing page, you have no advantage. If the answer is building a factory or signing 500 suppliers, you might.
An example. Two bike workshops charge 60 euros for the same repair. You buy parts in bulk and hold a small stock, so your parts cost per repair is 22 euros. Your competitor orders per job and pays 31 euros. Your margin is 38 euros against their 29. Across 300 repairs a month, that is 11,400 euros against 8,700 euros, a gap of 2,700 euros you can spend on marketing, or hand back as a lower price they cannot follow.
Founders confuse three different things. Differentiation means you are different. Advantage means the difference produces better economics for you. A feature is neither, because features get copied within one release cycle. Our team is experienced fails the test as well, since every competitor writes that sentence.
Write your advantage as a comparison with a number in it, and name the competitor you compare against. If you cannot fill in the number, the honest version says you compete on execution today and are building an advantage in a named area. That reads better than a claim a reader will test in the first meeting.
