SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Market sizing is time-consuming, error-prone, and often based on unsourced estimates; this Skill provides a repeatable, auditable TAM/SAM/SOM analysis so product teams and founders can make data-driven decisions for prioritization, fundraising, and go-to-market planning.

Core Features & Use Cases

  • Dual-method calculations: Always produces both top-down and bottom-up TAM estimates and triangulates differences with sensitivity checks.
  • Sourced research: Guides web research across industry reports, company filings, census and analyst data and requires citations for every numeric input.
  • Practical outputs: Produces SAM and SOM with filter rationales, realistic capture rates, year-by-year SOM projections, and a confidence assessment for pitch decks, PRDs, or investor materials.
  • Use case: Prepare a market-opportunity slide for a seed round by sizing the global and regional TAM and showing a conservative 3–5 year SOM backed by sources and calculations.

Quick Start

Ask the market-sizing skill to calculate TAM/SAM/SOM for [product name] with a short product description and target customer definition.

FAQPage Schema
How do I calculate TAM, SAM, and SOM for a pitch deck with cited sources?▼

The Skill produces structured TAM, SAM, and SOM market sizing analyses using both top-down and bottom-up calculations. It guides web research across industry reports and census data, requiring citations for every numeric input to ensure auditable traceable math.

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

Top-down market sizing estimates total market revenue from industry reports, while bottom-up calculates TAM by multiplying unit prices by target customer volumes. This Skill produces both methods and triangulates differences with sensitivity checks for reliable market analysis.

How to do market research for SAM and SOM projections for market-entry planning?▼

Market research for SAM and SOM projections requires defining target customers and applying filter rationales to total market data. This Skill generates year-by-year SOM projections with realistic capture rates and confidence assessments using cited competitive context.

Can I use bottom-up TAM estimates for a business case without manual web research?▼

Yes, you can generate bottom-up TAM estimates for a business case by providing a product and target customer definition. The Skill automates web research across company filings and analyst data to deliver sourced calculations without manual data gathering.

Does market sizing work for regional geography and specific time horizons?▼

Market sizing works for regional geography and specific time horizons by accepting optional geography and time-horizon inputs. It applies filter rationales to calculate SAM and delivers conservative multi-year SOM projections suitable for investor diligence.

Best way to triangulate TAM differences between top-down and bottom-up methods?▼

The best way to triangulate TAM differences is to calculate both top-down and bottom-up estimates simultaneously and apply sensitivity checks. This Skill automatically generates both methods and highlights differences to provide a confidence assessment for prioritization.
