What is the difference between TAM, SAM, and SOM in this skill?

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

Can I use this for both B2B and B2C markets?

Yes, the skill includes specific methodologies for SaaS (B2B), Marketplaces, and Consumer markets, adjusting metrics like Average Contract Value (ACV) or Average Revenue Per User (ARPU) accordingly.

Why is a bottom-up analysis preferred over top-down?

Bottom-up analysis is considered more credible by investors because it relies on granular customer segment data and specific pricing rather than broad, generalized industry reports.

How does the skill help validate market data?

It uses triangulation, guiding you to run multiple methodologies (e.g., top-down and bottom-up) and comparing the results to ensure they are consistent and defensible.
