Gordon Growth Model

The annualised rate of return that smooths out growth over multiple years, calculated as (ending value / beginning value)^(1/years) minus one. CAGR is used to compare growth trajectories of companies or metrics across different time periods.

The percentage increase in a company's revenue over a specific period, typically measured year-over-year or quarter-over-quarter. Revenue growth rate is a fundamental measure of business expansion, market traction, and the effectiveness of go-to-market strategy.

The percentage change in a metric from one year to the next, used to assess trends while neutralising seasonal effects. YoY growth rates in revenue, productivity, and intangible asset investment are fundamental to performance evaluation, valuation modelling, and growth accounting analysis.

The degradation in a machine learning model's predictive accuracy over time as the statistical properties of the input data diverge from the training data distribution. Model drift requires ongoing monitoring and periodic retraining to maintain performance, and is a key operational risk in production AI systems.

The rate at which a firm increases its output relative to its inputs over time. Productivity growth is a key indicator of operational efficiency and long-term competitiveness, closely linked to investment in intangible assets such as technology, training, and process improvement.

A business model in which a basic version of a product or service is offered free of charge while premium features, enhanced functionality, or expanded capacity are available for a subscription fee. The freemium model is prevalent in SaaS, enabling rapid user acquisition and product-led growth, with conversion rates from free to paid users typically ranging from 2% to 5%.

A business strategy that minimises investment in physical assets and instead relies heavily on intangible assets such as software, brand, data, and intellectual property to generate revenue. Asset-light companies typically exhibit higher scalability and return on capital but can be harder to value using traditional balance-sheet methods.

A business model that creates value by facilitating exchanges between two or more interdependent user groups — typically producers and consumers — through a digital platform. Platform businesses generate powerful network effects and intangible assets including user data, algorithmic matching capabilities, and brand trust.
