SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Market sizing helps stakeholders estimate revenue opportunity and prioritize investments by quantifying market scale across TAM, SAM, and SOM.

Core Features & Use Cases

  • Hybrid sizing methods (top-down, bottom-up, value theory) to triangulate market size.
  • Scenario planning (Bear/Base/Bull) with explicit assumptions and data sources.
  • Clear documentation of data sources, assumptions, and priors to support defensible conclusions.
  • Use Case: Evaluate market opportunity for a new product launch and synthesize outputs into executive-ready summaries.

Quick Start

Provide a market sizing brief for a target industry using TAM/SAM/SOM with data sources.

FAQPage Schema
How do I calculate TAM, SAM, and SOM for a new product launch?▼

Estimate TAM, SAM, and SOM by applying top-down, bottom-up, and value-theory methods to triangulate market size, requiring clearly defined assumptions, pricing benchmarks, target segments, and documented data sources.

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

Top-down market sizing estimates total opportunity from macro data, while bottom-up calculates it using pricing benchmarks and target segment volumes, and combining them creates a defensible scenario analysis.

Can I generate Bear, Base, and Bull scenario plans for enterprise software markets?▼

Yes, you can generate Bear, Base, and Bull scenario plans for enterprise software markets by documenting explicit assumptions and data sources to produce defensible market opportunity estimates.

What data sources do I need to estimate market opportunity accurately?▼

Estimating market opportunity accurately requires documented data sources, clearly defined assumptions, pricing benchmarks, and target segments to support credible TAM, SAM, and SOM conclusions across geographic contexts.

When should I use value-theory market sizing over standard bottom-up methods?▼

Use value-theory market sizing over bottom-up methods when evaluating new product categories where pricing benchmarks are undefined, allowing you to triangulate estimates based on delivered value.
