Market Sizing Frameworks
Frameworks and methodologies for estimating market size and validating market opportunity.
Overview
Market sizing answers the critical question: "Is this opportunity large enough to pursue?" It provides the foundation for strategic decisions, resource allocation, and investment prioritization.
Core Principle: Market sizing is educated guessing with documented assumptions. The goal is reasonable estimates and order-of-magnitude accuracy (is it $1M, $10M, or $100M?), not false precision.
Key Insight: Always use multiple methods (bottom-up, top-down, value theory) to triangulate and validate estimates. If methods disagree by more than 2-3x, your assumptions need scrutiny.
