Moat

What makes a business impossible to kill?

tip

In business, I look for economic castles protected by unbreachable moats — Warren Buffett

Warren Buffett scores moats by asking one question: what stops a well-funded competitor from taking your business? The answer breaks into nine distinct defenses. Score 5 or more and the castle holds.

This is why the Tight Five always asks "What do you control?" — your platform IS your moat inventory. Higher platform, deeper moat. Every capability you own that competitors must build from scratch is a defense that compounds.

Perceive

A moat is a sustainable competitive advantage that protects your business from competitors. It's what lets you keep the value you create rather than having it competed away.

The Nine Moats

#MoatWhat It MeansExample
1Network EffectsEach user makes the product more valuable for every other userSlack, Ethereum, LinkedIn
2Switching CostsLeaving costs more than staying — data, workflows, retrainingSalesforce, SAP, AWS
3Data MoatProprietary data that improves the product and cannot be replicatedBloomberg Terminal, Waze
4BrandTrust and recognition that commands premium pricingStripe, Notion, Figma
5Economies of ScaleUnit costs drop as volume grows — infrastructure amortizesGoogle Cloud, Cloudflare
6EmbeddingProduct becomes part of the customer's infrastructure — ripping it out breaks thingsTwilio, Stripe API, Auth0
7EcosystemThird-party developers build on your platform — their investment locks users inShopify Apps, Salesforce AppExchange
8Physical InfrastructureControlling atoms — land, sensors, buildings, equipment — that software alone cannot displaceHelium (hotspots), DIMO (vehicles), Hivemapper (dashcams)
9RegulatoryLicenses, certifications, or compliance barriers competitors must clearPlaid (banking), Palantir (clearance)

Scoring Guide

Score each moat 0 (absent), 1 (emerging), or 2 (strong). Sum all nine.

TotalVerdictAction
14-18FortressWiden. Invest in the strongest moats.
9-13DefensibleDeepen. Convert emerging moats to strong.
5-8VulnerableChoose. Pick 2-3 moats and commit.
0-4ExposedRethink. No defensibility means no margin.

The 5+ rule: A business with five or more active moats (score >= 1) is structurally secure. Below five, any well-funded competitor can replicate the product.

Moat Durability

Not all moats are equal.

Strong moats — widen over time, require continuous investment, are hard to replicate even with capital.

Weak moats — erode over time, can be copied with enough investment, depend on factors outside your control.

Question

Without a moat, any success attracts competition. Competition compresses margins. Eventually, no one profits.

The Value Capture Problem

Creating value is not enough. You must capture it.

  • No moat — you create value, competitors take it
  • Weak moat — you keep some value temporarily
  • Strong moat — you keep most value indefinitely

The AI and Crypto Question

Value Capture Questions

How will AI and crypto change moat dynamics?

Traditional MoatAI/Crypto Impact
DataAI commoditizes analysis; proprietary data becomes more valuable
Network EffectsToken incentives can bootstrap networks faster
Switching CostsInteroperability reduces switching costs
BrandReputation becomes verifiable on-chain

Act

1. Platform

Build infrastructure others depend on.

2. Process

Develop trade secrets and know-how.

  • Operational excellence
  • Unique methodologies
  • Codified best practices

3. People — Culture

Build a culture that attracts and retains talent.

  • Values and principles
  • Technical capabilities
  • Onboarding and development

How Moats Compound

Moats reinforce each other.

Physical Infrastructure → Data Moat → better product → Network Effects → more data
↓ ↓ ↓
Regulatory ←───── Switching Costs ← Embedding ← Ecosystem

The strongest companies stack moats. Stripe has embedding + ecosystem + brand + switching costs. That's four before they write a line of new code.

DePIN flips the script — physical infrastructure generates proprietary data that pure-software competitors cannot access. Sensors on farms, dashcams on roads, meters on buildings — atoms create the data moat that bits defend. Industries sitting on underutilized physical assets are the ripest targets for data-driven decisions that compound into defensibility.

Marketplace Moats

  • Stakeholder Intelligence — know your ecosystem better than anyone
  • Context Mapping — understand the jobs to be done
  • Distribution — own the path to customers

How do you build a moat before you have scale?

  • Which moat type compounds fastest for your specific business model?
  • When does a moat become a prison — locking you into a market that's shrinking?
  • What happens when AI commoditizes the moat you depend on most?
  • Which industries sit on physical assets generating data that nobody is capturing yet?
  • Which assumption in the standard framing of moats is most likely to be wrong in a 5-year horizon?
  • Which first principle, if violated, would make moat analysis fundamentally incorrect?
