Moat
Also known as: competitive moat, economic moat, defensibility
Definition
A business's ability to maintain a competitive advantage to protect its market share and long-term profits.
A structural barrier that protects a company from competitors, allowing it to sustain superior financial performance over time.
Why it matters
A great product will attract competitors. A strong moat protects your margins and makes it difficult for rivals to steal your customers. Examples include network effects, high switching costs, proprietary technology, and cost advantages.
Improvement tips
- Build high switching costs by integrating deeply into your customers' workflows.
- Leverage network effects where each new user adds value to the existing user base.
- Protect proprietary intellectual property and seek unique distribution channels.
Common mistakes
- Confusing a temporary head start or good branding with a sustainable structural moat.
- Failing to invest in defensibility while focusing solely on customer acquisition.
- Underestimating how fast technology or regulatory changes can erode a competitive advantage.
