FAQPage Schema
How do I calculate TAM SAM SOM with explicit assumptions for an investor pitch?▼

Calculate TAM, SAM, and SOM using a structured market-sizing workflow with built-in context collection and citation-backed data sources, producing a defensible market size summary suitable for an investor pitch.

What is the best way to structure market sizing with reproducible data citations?▼

Structure market sizing by guiding users through default questions on problem space, region, and target customers, then outputting a transparent calculation trail with step-by-step data sources for reproducible analysis.

How do I use a Python script to compute TAM SAM SOM deterministically?▼

Run the standalone market-sizing.py script with your population and ARPU values, or provide a pre-defined TAM, to deterministically compute and format your TAM, SAM, and SOM metrics.

Does market sizing for business case planning require predefined population and ARPU inputs?▼

Market sizing can accept predefined population and ARPU values to calculate results, but it can also take a pre-defined TAM to generate a formatted summary for your business case planning.

Can I use this approach for GTM planning across different industry segments?▼

Yes, this approach adapts to GTM planning by collecting context on your specific industry, segments, and target customers to ensure the market sizing output is relevant to your go-to-market strategy.

When should I not use automated market sizing for market analysis?▼

Avoid automated market sizing when you lack foundational data on target customers or regional parameters, as the workflow relies on explicit assumptions and citation-backed data to produce defensible market size calculations.
