FAQPage Schema
How do I calculate TAM, SAM, and SOM using a bottom-up approach for VC analysis?▼

Bottom-up market sizing calculates TAM, SAM, and SOM by decomposing ARPC across defined customer segments, applying segment classification and data-point collection to generate investment memo-ready estimates.

What is ARPC decomposition and how does it work for startup market sizing?▼

ARPC decomposition breaks down average revenue per customer to calculate market size across mutually exclusive segments, enabling data-backed segment analysis and precise bottom-up estimates for VC due diligence.

Can I run top-down sanity checks against bottom-up market sizing estimates?▼

Yes, top-down sanity checks validate bottom-up market sizing estimates by comparing segment-level ARPC calculations against broader market data to support scenario planning and investment memo preparation.

Does this market sizing workflow require predefined customer segments and ARPC data?▼

The workflow applies segment discovery with mutually exclusive definitions and requires ARPC structures to perform bottom-up market sizing, making it suitable for startup benchmarking and due diligence contexts.

What is the best way to prepare investment memos with TAM, SAM, and SOM calculations?▼

Automating bottom-up market sizing generates exportable tables, charts, and memo-ready summaries with source references, providing validated TAM, SAM, and SOM estimates for investment memo preparation.

Why use bottom-up market sizing instead of top-down estimates for venture capital due diligence?▼

Bottom-up market sizing provides granular ARPC-based calculations across defined customer segments, offering more data-backed market opportunity estimates than top-down approaches for informed VC decisions and startup planning.
