Which market sizing methodology is best for startups?

While top-down analysis is useful for quick validation, the bottom-up methodology is generally preferred by investors because it is based on granular customer data, specific pricing, and defensible assumptions.

Can this skill handle industry-specific market metrics?

Yes, the skill includes specialized considerations for SaaS (focusing on ACV), Marketplaces (focusing on GMV and Take Rate), and B2B Services (focusing on project value and frequency).

How does the skill help validate market assumptions?

It provides triangulation techniques, such as cross-checking bottom-up results against top-down industry reports and comparing figures with public company revenues to ensure the sizing is realistic.

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

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