Market Sizing & TAM Analysis FAQs

Question 1

How do I calculate market size for a disruptive new product?

Accepted Answer

Use the Value Theory methodology, which estimates market size based on the quantified economic value your solution creates and the customer's estimated willingness to pay for that value.

Question 2

What is a realistic SOM percentage for a new business?

Accepted Answer

For most early-stage startups, a realistic SOM is typically estimated between 2% and 5% of the Serviceable Available Market (SAM) within a 3 to 5-year timeframe.

Question 3

Does this skill support different business models?

Accepted Answer

Yes, it provides specific metrics and calculation frameworks for SaaS (ACV/Expansion), Marketplaces (GMV/Take Rate), and Consumer markets (ARPU/Frequency).

Question 4

What is the difference between TAM, SAM, and SOM?

Accepted Answer

TAM (Total Addressable Market) is the total global opportunity, SAM (Serviceable Available Market) is the portion you can realistically target with your current product/geography, and SOM (Serviceable Obtainable Market) is the market share you expect to capture in 3-5 years.

Bottom-up analysis is generally preferred by investors as it is more granular, defensible, and built from specific customer segments and pricing data rather than broad industry reports.
