Yes, you can cross-validate market sizing estimates by triangulating figures from Top-down, Bottom-up, and Value Theory methodologies. This triangulation increases confidence in your TAM, SAM, and SOM calculations for strategic business decisions.

What data do I need to estimate Total Addressable Market for a B2B SaaS product?▼

To estimate Total Addressable Market for a B2B SaaS product, you need web research data for industry trends and internal metrics for bottom-up calculations. This combination ensures your market opportunity figures are robust and defensible.
