What is a competitive moat?
A moat is a structural advantage that makes your position harder to attack over time — network effects, switching costs, proprietary data, economies of scale, or brand. Features are not moats. If a well-funded competitor could copy it in a quarter, it's a lead, not a moat.
The five that hold up
Network effects — the product improves as more people use it. Strongest when the network is global rather than local.
Switching costs — leaving is expensive in data, retraining, integration or risk. This is what makes unglamorous enterprise software so durable.
Proprietary data — usage generates data that makes the product better, which attracts usage. Google Maps is the definitive version: years of corrections, traffic patterns and Street View imagery that a competitor cannot simply buy.
Scale economics — unit costs fall as you grow, so you can price where entrants can't follow.
Brand — when a category name and a product name converge, acquisition gets structurally cheaper.
Distribution counts too
Stripe's advantage is often described as developer experience, which is a feature and copyable. The durable part is what that experience produced: default status in a generation of developers' mental toolkit, plus the integration depth that follows once payments run through your code. That's brand and switching cost compounding out of what began as a documentation advantage.
The pattern generalises. Features aren't moats, but features can be the mechanism that builds one, if you're deliberate about which structural asset they accumulate into.
The test to run on your own product
Imagine a competitor with three times your funding and a copy of your product. What still stops them? If the honest answer is "nothing, we'd just have to be faster", you don't have a moat yet — and knowing that is more useful than the flattering answer.

Related questions
Is being first to market a moat?
No, on its own. First-mover advantage only becomes a moat if you convert the head start into something structural — a network, accumulated data, or switching costs. Plenty of first movers were overtaken by a better-funded second mover who arrived eighteen months later.
Are network effects always the strongest moat?
They're the most celebrated, but they can be local and fragile. Network effects that operate city-by-city or team-by-team can be attacked market-by-market, which is how challengers beat incumbents that looked networked and were actually a hundred small networks.
Can a startup have a moat early?
Rarely a mature one, but it can be building toward one deliberately. The useful early question is which of the five categories your work compounds into — if none of them, you're competing on execution speed alone, which is a real strategy but an exhausting one.
