FAQPage Schema
How do I calculate TAM, SAM, and SOM for my business?▼

TAM (Total Addressable Market), SAM (Serviceable Addressable Market), and SOM (Serviceable Obtainable Market) are calculated using top-down, bottom-up, and value-theory methodologies. This skill applies explicit formulas and step-by-step calculations across industries and geographies to produce defensible market-size estimates with documented assumptions.

What's the difference between top-down and bottom-up market sizing approaches?▼

Top-down market sizing starts with total industry revenue and segments downward to your addressable portion; bottom-up builds from unit economics and customer acquisition upward. This skill implements both methodologies to cross-validate market opportunity estimates and strengthen investor credibility.

How do I segment my market into TAM, SAM, and SOM?▼

Market segmentation breaks the total market into addressable segments (SAM) based on geography, industry, or customer type, then into obtainable segments (SOM) based on realistic capture. This skill justifies each segment boundary and quantifies the progression from total to serviceable to obtainable markets.

Can I apply market sizing to different industries and geographies?▼

Yes. This skill applies TAM, SAM, and SOM calculations across industries and geographies, adjusting methodologies to match sector-specific dynamics. It accounts for regional variations and industry-specific benchmarks to produce contextually accurate estimates.

What limitations should I know about market sizing estimates?▼

Market sizing relies on assumptions about customer adoption, competitive dynamics, and available data accuracy. This skill documents all assumptions explicitly and identifies known limitations so you understand confidence levels and can defend estimates to investors and stakeholders.

How do I use market sizing in an investor pitch?▼

Market opportunity quantification (TAM, SAM, SOM) demonstrates addressable demand and revenue potential to investors. This skill produces defensible, formula-driven estimates with transparent assumptions and methodology, making your pitch more credible and less vulnerable to investor scrutiny.
