Calculates TAM, SAM, and SOM using three methodologies: top-down from industry reports, bottom-up from customer segments, and value theory from willingness to pay. Walks you through the complete framework with formulas, data sources, and validation checks. Use it when building investor decks, validating startup opportunities, or sizing markets for business plans. The bottom-up methodology is most credible with VCs since it builds from actual customer data rather than industry estimates. Includes realistic penetration rates and warns against common red flags like claiming more than 10% market share as a new entrant.
