Estimate market opportunity using bottom-up calculations from target segments, price, and geography, then validate with top-down industry data. Triangulating multiple methods produces defensible TAM, SAM, and SOM estimates for startup opportunities.

Bottom-up market sizing builds TAM, SAM, and SOM from target segments, price, and geography, while top-down sizing validates estimates using industry data. Applying both methods triangulates market opportunity for more credible results.

Use value-theory sizing to quantify potential value and willingness to pay for new product categories. It complements bottom-up and top-down methods by estimating market opportunity when traditional industry data is unavailable.

Yes, market sizing applies across geographies, industries, and customer segments. Define your target market inputs and document data sources, assumptions, and methodology steps to produce segment-specific TAM, SAM, and SOM estimates.

Document data sources, assumptions, and methodology steps alongside your calculations. Recording these inputs throughout bottom-up, top-down, and value-theory sizing ensures your TAM, SAM, and SOM estimates are transparent and defensible.
