What market-sizing-analysis does

The skill breaks a market into three levels: total potential (TAM), the portion a product can serve (SAM), and a realistic share to capture (SOM). It offers top-down analysis based on industry reports, bottom-up calculations from customer segments, and value theory based on what buyers may pay for a solution.

Choose the method that fits the market. Industry research suits mature markets, customer-based calculations suit new or niche markets, and value theory is intended for new categories. Worked examples are in references/details.md. Install it when you need to assess a startup opportunity or prepare investor-facing market analysis; it is unnecessary for product work that does not involve market sizing.

What it helps with

  • estimate a startup's total addressable market
  • identify the segment a product can serve
  • calculate a realistic obtainable market share
  • compare industry research with customer-based estimates
  • prepare market analysis for a business plan

Example prompts for the agent

  • Estimate TAM, SAM, and SOM for our product using a bottom-up approach.
  • Use industry reports to size this market and identify the segment our product can serve.
  • Estimate what customers might pay to solve this problem.

# Market Sizing Analysis

Comprehensive market sizing methodologies for calculating Total Addressable Market (TAM), Serviceable Available Market (SAM), and Serviceable Obtainable Market (SOM) for startup opportunities.

## Overview

Market sizing provides the foundation for startup strategy, fundraising, and business planning. Calculate market opportunity using three complementary methodologies: top-down (industry reports), bottom-up (customer segment calculations), and value theory (willingness to pay).

## Core Concepts

### The Three-Tier Market Framework

**TAM (Total Addressable Market)**

- Total revenue opportunity if achieving 100% market share
- Defines the universe of potential customers
- Used for long-term vision and market validation
- Example: All email marketing software revenue globally

**SAM (Serviceable Available Market)**

- Portion of TAM targetable with current product/service
- Accounts for geographic, segment, or capability constraints
- Represents realistic addressable opportunity
- Example: AI-powered email marketing for e-commerce in North America

**SOM (Serviceable Obtainable Market)**

- Realistic market share achievable in 3-5 years
- Accounts for competition, resources, and market dynamics
- Used for financial projections and fundraising
- Example: 2-5% of SAM based on competitive landscape

### When to Use Each Methodology

**Top-Down Analysis**

- Use when established market research exists
- Best for mature, well-defined markets
- Validates market existence and growth
- Starts with industry reports and narrows down

**Bottom-Up Analysis**

- Use when targeting specific customer segments
- Best for new or niche markets
- Most credible for investors
- Builds from customer data and pricing

**Value Theory**

- Use when creating new market categories
- Best for disruptive innovations
- Estimates based on value creation
- Calculates willingness to pay for problem solution
