# What Is Moat?

> A moat is a durable competitive advantage that makes a business hard to copy or displace—through network effects, switching costs, scale, brand, or proprietary assets—so profits can persist after competitors arrive.

**Moat** describes how well a company can defend its position after competitors notice the opportunity—whether through [network effects](/glossary/network-effects), [switching costs](/glossary/switching-costs), scale economics, brand, regulation, or proprietary technology.

### How it works

The term comes from Warren Buffett's metaphor: a castle protected by a wide moat is harder to attack. In venture, investors map moats to specific mechanisms, not slogans.

Common moat types include:

- **Network effects:** Each new user makes the product more valuable (marketplaces, social graphs, payment rails).
- **Switching costs:** Migration pain—data, integrations, training, or workflow lock-in—keeps customers from leaving.
- **Scale or cost advantage:** Lower unit costs at volume (logistics density, compute amortization, purchasing power).
- **Brand and trust:** Especially in fintech, healthcare, or enterprise where failure is costly.
- **Regulatory or IP barriers:** Licenses, patents, or compliance expertise that slow entrants.

A seed-stage company may have a *nascent* moat—early retention, a wedge workflow, or a data flywheel not yet proven at scale. Series B diligence usually demands evidence: cohort retention, pricing power, win rates against incumbents.

### Why it matters

- **Founders:** Pitch the mechanism ("integrations into ERP create 18-month switching cost") rather than "we have no competition." Weak moats mean you must out-execute forever on sales and product.
- **Investors:** Moat quality drives terminal margin assumptions in models. A fast-growing business without defensibility often gets marked down when growth slows.

### Common mistake

Calling speed or capital alone a moat. Being first to market helps only if you convert early share into a structural advantage before well-funded copycats ship.

## FAQ

### What is a moat in simple terms?

A moat is what keeps rivals from eating your lunch once they see your model works. It might be a user network that gets better with scale, data nobody else has, or contracts that lock customers in for years.

### Why does moat matter?

Venture returns depend on sustained margins and market share, not a one-year growth spike. Investors probe moats because many startups can grow quickly before copycats compress pricing and retention.
