SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Estimates market opportunity by combining TAM, SAM, and SOM analyses with timing signals, enabling data-driven prioritization of growth initiatives.

Core Features & Use Cases

  • Dual-method TAM estimation (top-down and bottom-up) with sources and uncertainty ranges.
  • SAM and SOM calculations through a documented filter chain (geography, segment, technology, vertical) and 12-24 month capture-rate framing.
  • Timing assessment grounded in industry signals to inform go-to-market timing and investment decisions.
  • Mode-specific validation guidance for venture and bootstrap contexts to determine viability.

Quick Start

Run a TAM/SAM/SOM market sizing analysis for your target industry and geography in the BUILD phase.

FAQPage Schema
How do I calculate TAM, SAM, and SOM for a target market?

Estimate market opportunity by applying dual-method TAM, SAM, and SOM analysis with a documented filter chain for geography, segment, technology, and vertical. This yields uncertainty ranges with source citations and capture-rate framing for growth initiatives.

What is the difference between top-down and bottom-up TAM estimation?

Top-down TAM estimation derives market size from broader industry data, while bottom-up builds estimates from unit economics and customer counts. This dual-method approach cross-validates market opportunity ranges, reducing uncertainty in sizing a problem space.

How do I assess go-to-market timing signals for market sizing?

Assess go-to-market timing by analyzing industry signals alongside TAM, SAM, and SOM calculations. This timing analysis grounds investment decisions and prioritizes growth initiatives using a 12 to 24 month capture-rate framing.

Can I use TAM SAM SOM analysis for both venture and bootstrap contexts?

TAM, SAM, and SOM analysis provides mode-specific validation guidance for both venture and bootstrap contexts. It determines viability by applying documented filter chains and data provenance to derive opportunity ranges for different investment models.

What data sources do I need for market opportunity sizing?

Market opportunity sizing requires data sources supporting dual-method TAM estimation and a documented filter chain covering geography, segment, technology, and vertical. Clear source citations establish data provenance for resulting TAM, SAM, and SOM tiers.

When should I apply geography and segment filters during market sizing?

Apply geography, segment, technology, and vertical filters during the SAM and SOM calculation phase to narrow the broader TAM. This documented filter chain derives specific market opportunity ranges and 12 to 24 month capture-rate estimates.
