Moat
What makes a business impossible to kill?
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
| # | Moat | What It Means | Example |
|---|---|---|---|
| 1 | Network Effects | Each user makes the product more valuable for every other user | Slack, Ethereum, LinkedIn |
| 2 | Switching Costs | Leaving costs more than staying — data, workflows, retraining | Salesforce, SAP, AWS |
| 3 | Data Moat | Proprietary data that improves the product and cannot be replicated | Bloomberg Terminal, Waze |
| 4 | Brand | Trust and recognition that commands premium pricing | Stripe, Notion, Figma |
| 5 | Economies of Scale | Unit costs drop as volume grows — infrastructure amortizes | Google Cloud, Cloudflare |
| 6 | Embedding | Product becomes part of the customer's infrastructure — ripping it out breaks things | Twilio, Stripe API, Auth0 |
| 7 | Ecosystem | Third-party developers build on your platform — their investment locks users in | Shopify Apps, Salesforce AppExchange |
| 8 | Physical Infrastructure | Controlling atoms — land, sensors, buildings, equipment — that software alone cannot displace | Helium (hotspots), DIMO (vehicles), Hivemapper (dashcams) |
| 9 | Regulatory | Licenses, certifications, or compliance barriers competitors must clear | Plaid (banking), Palantir (clearance) |
Scoring Guide
Score each moat 0 (absent), 1 (emerging), or 2 (strong). Sum all nine.
| Total | Verdict | Action |
|---|---|---|
| 14-18 | Fortress | Widen. Invest in the strongest moats. |
| 9-13 | Defensible | Deepen. Convert emerging moats to strong. |
| 5-8 | Vulnerable | Choose. Pick 2-3 moats and commit. |
| 0-4 | Exposed | Rethink. 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
How will AI and crypto change moat dynamics?
| Traditional Moat | AI/Crypto Impact |
|---|---|
| Data | AI commoditizes analysis; proprietary data becomes more valuable |
| Network Effects | Token incentives can bootstrap networks faster |
| Switching Costs | Interoperability reduces switching costs |
| Brand | Reputation becomes verifiable on-chain |
Act
1. Platform
Build infrastructure others depend on.
- Proprietary Data combined with Compute Power
- Physical assets and distribution networks
- Developer platforms and ecosystems
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
Financial Moats
| Element | Moat Contribution |
|---|---|
| Cost Structure | Lower costs = pricing power |
| Cash Generation | Fund investment in widening moat |
| Revenue Diversity | Reduce dependence on any single source |
