Market Sizing Analysis

This walks you through calculating TAM, SAM, and SOM using three methodologies: top-down from industry reports, bottom-up from customer segments, and value theory based on willingness to pay. You get formulas, step-by-step processes, and specific guidance on when to use each approach. Good for startup planning, pitch decks, or anytime you need defensible market size numbers. The bottom-up methodology is what investors actually care about, and the skill includes realistic capture rates and validation techniques to cross-check your numbers. It's comprehensive but you'll still need to do the research legwork yourself.
