Can I use this for investor pitch decks?

Yes, the skill provides the structured framework, formulas, and validation steps needed to create credible, defensible market sizing slides for venture capital and angel investors.

What market sizing methodologies does this skill support?

It supports three core methodologies: Top-Down (using industry reports), Bottom-Up (calculating from customer segments), and Value Theory (estimating based on problem-solving value).

Why does the skill emphasize bottom-up analysis?

Bottom-up analysis is considered the most credible by investors because it relies on granular customer data and pricing rather than broad, sometimes inflated, industry reports.

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

TAM is the total global revenue opportunity; SAM is the portion you can realistically target with your current product/geography; SOM is the market share you expect to capture within 3-5 years.
