Moat

Brand, network effects, switching costs, proprietary data, regulatory licences and genuine economies of scale are moats. Being first, working harder and having a good idea are not.

Ask what happens if a well-funded competitor decides to do exactly what you do tomorrow. If the honest answer is "they win", you have a product, not a business.

Two agencies do identical work. One is a talented team; the other holds forty clients on annual contracts, with their reporting and their history inside a system it would take a fortnight to leave. A competitor undercutting the first wins immediately. To take the second, it has to win forty separate arguments against the cost of moving.

Moats are built deliberately, and they are boring: contracts rather than handshakes, integrations that become a step in the customer's own process, a licence not everyone can obtain, a name people type into search directly. The test is simple - if you woke up tomorrow with the same product, the same skills and no reputation, how long until you were back where you are? A short answer is not a moat.
