Pat Dorsey’s framework is one of the clearest and most practical ways to think about competitive advantage.
The brilliance of this framework lies in its simplicity. Many investors speak about moats, but they often confuse a very good business with an exceptional business that possesses a wide economic moat. A company can have excellent products, wonderful services with amazing customer service, talented management, strong growth, and happy customers, yet still lack a durable competitive advantage.
A moat is not merely excellence. A moat is a structural barrier that makes competition difficult.
“If competitors wanted to attack this business, what would stop them?”
If the answer is unclear, the moat may not exist.
Understanding the Economic Moat
The term “economic moat” was popularised by Warren Buffett. Just as a medieval castle was protected by a moat filled with water, a business is protected by barriers that keep competitors away from its profits.
The purpose of a moat is straightforward: protect profitability, protect market share, protect returns on capital, and allow the company to compound value over long periods. Without a moat, competition eventually drives returns down.
History provides countless examples. A company launches a wonderful product. Customers love it. Profits soar. Competitors notice. They enter the market. Prices fall. Margins shrink. The original company loses its advantage. The product may still be excellent, but the economics deteriorate.
This is why investors should focus less on products and more on structures. Dorsey’s framework helps us do exactly that.
Moat Type 1: Intangible Assets
Intangible assets are things competitors cannot easily reproduce: brands, patents, regulatory licenses, certifications, legal permissions, and intellectual property.
Not all brands create moats. Many brands are popular without possessing pricing power. A true brand moat allows a company to charge more than competitors while maintaining customer loyalty.
Example: The Coca-Cola Company
Consumers often have strong preferences for Coca-Cola over generic alternatives despite similar ingredients and significantly higher prices. The value is not in the formula alone. It exists in brand recognition, consumer habit, emotional association, and global distribution. A new competitor can create a cola tomorrow. Replicating over a century of consumer trust is far more difficult.
Example: Moody's Corporation
Moody’s possesses a powerful regulatory moat. Its credit ratings are deeply embedded within global financial regulations and investment processes. The challenge for a new entrant is not creating a rating system. The challenge is convincing regulators, institutions, and markets to trust it. Trust accumulated over decades becomes an intangible asset.
Intangible assets often allow companies to charge premium prices, earn higher margins, maintain customer loyalty, and resist competitive attacks. Luxury goods companies such as Hermès and LVMH provide additional examples — the physical materials alone do not justify their prices. The brand does.
Moat Type 2: Switching Costs
Switching costs exist when customers face significant inconvenience, expense, risk, or disruption when changing suppliers. The customer may dislike the current provider. Yet the cost of switching is so high that they stay. This moat is especially common in business software.
Example: Microsoft Corporation
Large organisations run critical operations through Windows, Microsoft Office, and Azure integrations. Changing these systems can require employee retraining, data migration, new workflows, and operational disruption. The software itself may not be irreplaceable. The cost of changing often is.
Example: Oracle Corporation
Many large enterprises store decades of critical data in Oracle databases. Migrating away can take years, with risks including downtime, security issues, data loss, and massive consulting expenses. As a result, Oracle has enjoyed remarkable customer retention over the last several decades.
Example: ServiceNow, Inc.
ServiceNow helps organisations manage workflows across departments. Once embedded deeply into an enterprise, replacing it becomes very difficult due to organisational and user inertia. Processes become customised, employees become trained, and data accumulates. The switching costs rise over time.
Investors often underestimate this moat. Customers do not need to love the product. They merely need to find switching very unattractive. This creates stable revenue, predictable cash flow, high renewal rates, and strong pricing power.
Moat Type 3: Network Effects
Network effects are among the most powerful moats ever discovered. A network effect occurs when a product becomes more valuable as more people use it. Each additional user increases the value for existing users, creating a self-reinforcing cycle.
Example: Visa Inc.
Visa’s payment network demonstrates textbook network effects, spanning consumers, merchants, banks, and payment processors. Consumers want cards accepted everywhere. Merchants want the cards that consumers already carry. Banks want access to both. Every new participant increases value for everyone else. A competitor must persuade all groups to join simultaneously — extraordinarily difficult.
Example: Meta Platforms, Inc.
Social networks illustrate network effects clearly. People use social platforms because other people are already there. The more users join, the more useful the platform becomes. Building the technology is relatively easy. Building the network is not.
In general, many businesses become more valuable as they grow, and most become harder to compete against as they grow. Businesses with a network effect economic moat often experience both simultaneously — which explains why companies with strong network effects can dominate industries for decades.
Moat Type 4: Cost Advantages
Cost advantages exist when a company can produce goods or services at a significantly lower cost than its competitors. The advantage must be structural rather than temporary. Temporary efficiency is not a moat. Structural efficiency is.
Example: Costco Wholesale Corporation
Costco operates with extraordinary scale — high inventory turnover, membership fees, limited product selection, and strong supplier relationships. These factors allow Costco to maintain lower prices than many competitors. Matching Costco’s economics requires replicating its entire system.
Example: GEICO
Historically, GEICO built a low-cost insurance model based heavily on direct distribution. By reducing reliance on traditional agent networks, it achieved lower operating costs, allowing competitive pricing while maintaining profitability. This cost structure took decades to build in the pre-internet era.
Example: Ryanair Holdings plc
Ryanair has become one of the lowest-cost airlines in the world through high aircraft utilisation, operational simplicity, cost discipline, and efficient airport selection. Competitors often struggle to match its costs because doing so would require redesigning their entire operating model.
In many industries, customers view products as largely interchangeable. When that happens, cost becomes decisive. The lowest-cost producer can charge lower prices, earn higher profits, gain market share, and survive downturns better.
What Is Not a Moat?
This may be the most important lesson in Dorsey’s framework. Many characteristics that investors admire are not moats.
Great products
A great product can be copied. History is full of examples. The original innovator often loses leadership once competitors enter. Innovation alone is not protection.
Great customer service
Excellent service attracts customers. However, competitors can often imitate service standards. Customer service helps a moat. It is rarely the moat itself.
Great management
Exceptional leaders matter enormously. Yet investors should ask: what happens when the CEO retires? If the competitive advantage disappears alongside management, it was never a moat. It was managerial skill.
Fast growth
Growth is not a moat. Many rapidly growing businesses eventually face intense competition. The key question remains: what protects future profits?
Why Compounders Usually Have Moats
Many investors seek “compounders” — businesses capable of reinvesting capital at attractive rates for long periods. Most great compounders possess one or more moat types. Importantly, many great compounders possess more than one moat simultaneously.
Visa
Microsoft
Moody's
The strongest businesses often have overlapping moats.
Applying Dorsey’s Framework as an Investor
Before investing in any company, ask several questions.
Five questions to ask before investing
What prevents competitors from copying this business?
Does the company possess intangible assets, switching costs, network effects, or cost advantages?
Would the advantage still exist if management changed tomorrow?
Could a well-funded competitor realistically overcome the moat within five years?
Is the moat strengthening or weakening?
These questions often reveal weaknesses hidden beneath impressive growth stories.
Final Thoughts
Pat Dorsey’s greatest contribution to investing may be reducing the concept of competitive advantage to four simple categories. Many investors overcomplicate the subject. Dorsey’s framework brings clarity.
A durable moat almost always comes from one or more of intangible assets, switching costs, network effects, or cost advantages. Nothing else consistently explains long-term excess returns.
A great product may attract customers. A charismatic CEO may inspire employees. Outstanding customer service may create goodwill. Rapid growth may excite investors. Yet none of these automatically creates a moat.
A moat is structural. It remains standing even when products and services evolve, managers retire, and industry dynamics change.
For long-term investors seeking businesses capable of compounding capital over decades, one question should always come before valuation, growth forecasts, or earnings estimates:
Which of Dorsey’s four moats protects this business?
If you can identify one clearly, you may have found the foundation of a long-term compounder. If you cannot identify one, further investigation is warranted before assuming the company possesses a durable competitive advantage.
