A competitive moat is a durable advantage that makes it hard for competitors to take your customers, such as switching costs, proprietary data, brand trust, or deep specialization. Moats protect margin over time by making you difficult to replace rather than merely better today.

Anything you can do that a competitor can copy in a quarter is not a moat, it is a feature. The moats available to a services or SaaS firm at your size are usually specialization, accumulated proof, and trust. Those compound slowly and cannot be bought, which is exactly why they hold when a better-funded competitor shows up.

Example:

Deep specialization in one buyer type creates a moat because a generalist competitor cannot credibly claim the same depth without abandoning their own market.

What kinds of moats can a smaller company build?

Specialization, accumulated proof and reputation, switching costs, and proprietary data or process. These compound with time rather than requiring large capital.

Why is being better not a moat?

Being better is temporary and copyable. A moat is structural, meaning a competitor cannot match it without giving up something they are unwilling to give up.
