TAM (Total Addressable Market), SAM (Serviceable Addressable Market), and SOM (Serviceable Obtainable Market) are calculated using three methodologies: top-down (starting from total market size), bottom-up (building from unit economics), and value-theory (pricing-based approaches). Provide your product, geography, and pricing to generate an investor-ready analysis with transparent calculations and cited data sources.

Top-down sizing starts with total industry revenue and applies market share percentages downward. Bottom-up sizing builds from customer units, price per unit, and addressable segments upward. This Skill applies both methods alongside value-theory approaches and triangulates results to validate market estimates with credible sources for investor presentations.

Yes. This Skill produces investor-ready TAM/SAM/SOM analyses with executive summaries, transparent assumptions, explicit inputs, source citations, and clearly structured output formats designed for VC and startup fundraising contexts.

Provide your product description, target geography or regions, and pricing strategy. The Skill applies top-down, bottom-up, and value-theory methodologies using credible data sources to calculate TAM, SAM, and SOM with documented assumptions and source citations.

The Skill triangulates across three independent methodologies—top-down, bottom-up, and value-theory—to validate estimates and surface disagreements. Clear documentation of inputs, assumptions, and data sources builds credibility for investor review and reveals where market estimates diverge.
