FAQPage Schema
How do I estimate TAM, SAM, and SOM for market entry and investor pitches?

Estimate TAM, SAM, and SOM by applying both top-down and bottom-up approaches to your product context, geography, and customer segments, generating numeric estimates, growth projections, and clearly stated assumptions for investor pitches.

What is the difference between top-down and bottom-up market sizing?

Top-down market sizing starts with broad industry totals and narrows down to specific segments, while bottom-up sizing builds estimates from individual product pricing and unit sales, allowing you to reconcile numbers for transparent strategic planning.

How do I calculate serviceable obtainable market share with clear assumptions?

Calculate serviceable obtainable market (SOM) by defining your target geography, industry, and customer segments, then mapping explicit growth assumptions and scenario-based projections to estimate the realistic market share you can capture.

What inputs do I need to generate market sizing projections for go-to-market planning?

To generate market sizing projections for go-to-market planning, you need to provide your product context, target geography, industry, customer segments, and time horizon to receive reconciled market definitions and actionable insights.

Can I use bottom-up market sizing for strategic planning in specific customer segments?

Yes, you can use bottom-up market sizing for strategic planning by applying it to specific customer segments and geography, producing structured outputs with explicit assumption mapping and sources to support transparent decision-making.
