Moat

TL;DR

A structural advantage that protects a business from competition over time — network effects, switching costs, scale, brand, or proprietary technology.

A moat is anything that keeps competitors at bay long enough for the business to compound. Hamilton Helmer's '7 Powers' enumerates the durable ones: scale economies, network effects, counter-positioning, switching costs, branding, cornered resource, and process power. Most billion-dollar companies have at least two.

Moats are easier to identify in retrospect than to engineer in advance. The strongest startup moats usually emerge from a deliberate product or distribution choice that becomes structurally hard to copy as the company scales.

Worked example

Visa's moat is a two-sided network effect plus 30+ years of merchant integrations. A new payment network can't profitably acquire a single merchant until it has cardholders, and can't acquire cardholders without merchants — the chicken-and-egg lock is the moat.

Common pitfalls

• Confusing 'we have a patent' with 'we have a moat'.
• Treating first-mover advantage as a moat — it usually isn't.
• Optimizing growth in ways that prevent the moat from forming.

The Defensibility or Moat slide names the specific mechanism (network effect, switching cost, data flywheel) and shows how it strengthens with scale.
