Price Elasticity
A measure of how sensitive customer demand is to changes in price, quantifying the percentage change in quantity demanded relative to a percentage change in price, essential for optimizing pricing strategies.
Price elasticity quantifies the relationship between price changes and demand changes. Elastic demand means customers are highly price-sensitive and small price increases cause significant demand drops. Inelastic demand means customers are relatively insensitive to price changes, allowing for price increases without major volume loss.
For growth teams, understanding price elasticity by segment and product is fundamental to pricing optimization and revenue growth. AI models can estimate elasticity at granular levels, determining not just overall price sensitivity but how it varies by customer segment, time period, competitive context, and product category. Growth engineers should build experimentation frameworks that safely test price variations across segments to empirically measure elasticity rather than relying on assumptions. Randomized pricing experiments must be designed carefully to avoid customer backlash and legal issues. The most valuable insight is often that elasticity varies dramatically across segments: price-sensitive customers may need discounts to convert, while value-focused customers respond to premium positioning. This knowledge enables personalized pricing strategies that maximize total revenue across the customer base rather than optimizing for a single price point.

Recommendation Engine
A system that uses algorithms and machine learning to suggest relevant items, content, or actions to users based on their behavior, preferences, and similarities to other users, driving engagement and conversion.
Collaborative Filtering
A recommendation technique that predicts a user's preferences by analyzing behavior patterns across many users, based on the principle that people who agreed in the past tend to agree in the future.
Content-Based Filtering
A recommendation approach that suggests items similar to those a user has previously liked or interacted with, based on item attributes and features rather than the behavior of other users.
Matrix Factorization
A mathematical technique used in recommendation systems that decomposes the large, sparse user-item interaction matrix into lower-dimensional latent factor matrices, revealing hidden patterns that predict user preferences.
Cold-Start Problem
The challenge of providing relevant recommendations or personalized experiences to new users with no interaction history or for new items with no engagement data, a fundamental limitation of data-driven personalization systems.
Popularity Bias
The tendency of recommendation systems to disproportionately suggest already popular items, creating a feedback loop where popular items get more exposure and engagement, further reinforcing their dominance over niche content.
