Competitive Moat
A sustainable competitive advantage that protects a business from competitors, creating durable barriers that are difficult or costly to replicate, such as network effects, proprietary data, or switching costs.
A moat is what keeps competitors from simply copying your product and stealing your customers. Without a moat, success attracts competition that erodes margins until the opportunity is competed away. Warren Buffett popularized the concept: the widest moats protect the most durable businesses. In technology, common moats include network effects, data advantages, switching costs, brand, economies of scale, and proprietary technology.
For AI-powered products, data moats are the most defensible. Proprietary training data that improves model quality creates a virtuous cycle: better models attract more users, who generate more data, which trains even better models. This compounding advantage is extremely difficult to replicate because a competitor cannot buy the data or shortcut the accumulation process. They need the users to generate the data, but they need the data to build the product that attracts users.
Growth teams contribute to moat building by driving the behaviors that strengthen competitive advantages. Encouraging data contribution strengthens data moats. Building collaboration features strengthens network effects. Creating integrations and workflows increases switching costs. Growing the user community strengthens brand moats. Every growth initiative should be evaluated not just on immediate metrics but on whether it deepens the company's long-term competitive position.

Growth Loop
A self-reinforcing cycle where each cohort of users generates inputs (data, content, referrals) that attract the next cohort, creating compounding growth.
Churn
The rate at which customers stop using or paying for a product over a given period, typically measured as monthly or annual churn percentage.
Activation Rate
The percentage of new signups who complete a key action (the 'aha moment') that correlates with long-term retention and product value realization.
Product-Led Growth (PLG)
A go-to-market strategy where the product itself drives acquisition, activation, and expansion through self-serve experiences rather than sales-led motions.
Viral Coefficient (K-Factor)

Net Revenue Retention (NRR)
The percentage of recurring revenue retained from existing customers over a period, including expansion, contraction, and churn — where 100%+ indicates growth without new customers.
