# Market Research

## When to Use
Activate when a founder needs to size a market opportunity using TAM/SAM/SOM, validate market assumptions for a pitch deck, understand growth trends, evaluate market entry, or prepare for investor conversations about addressable market. Trigger phrases include "how big is our market," "TAM/SAM/SOM," "market size," "market opportunity," "is this market big enough," "market trends," "help me with the market slide," or "validate our market assumptions."

## Context Required
- **From startup-context:** product description, target customer segments, pricing model, geographic scope, business model.
- **From the user:** the market or segment to analyze, known data points (industry reports, customer counts, pricing benchmarks), geographic and industry constraints, whether this is for internal decision-making or external presentation (investor deck), and any specific hypotheses about market dynamics.

## Workflow
1. **Define market boundaries** -- Specify the problem space, customer segments, geography, and constraints. "Project management tools" is a different market than "team collaboration software." Precision determines whether the analysis is useful.
2. **Top-down estimation** -- Start from total industry size using industry reports, public company revenues, and government statistics. Narrow to the relevant segment by applying filters for geography, customer type, and product category.
3. **Bottom-up estimation** -- Build independently from unit economics: (number of potential customers) x (price per customer) x (purchase frequency). Cross-validate against the top-down estimate.
4. **Scope the SAM** -- Identify which portion of TAM is realistically serviceable given current product capabilities, pricing, distribution channels, and geographic reach.
5. **Estimate the SOM** -- Project achievable market share in 1-3 years based on competitive position, go-to-market capacity, and current traction.
6. **Project growth** -- Forecast how TAM, SAM, and SOM evolve over 2-3 years. Identify key growth drivers, technology shifts, regulatory changes, and demographic trends.
7. **Map assumptions** -- Surface every critical assumption underlying each estimate. Rate confidence levels and identify how to validate the most uncertain assumptions.

## Output Format

### Market Definition
One paragraph defining the problem space, customer need, geographic and segment boundaries, and key scoping decisions.

### TAM / SAM / SOM

| Metric | Current Estimate | 2-3 Year Projection | Method | Confidence |
|---|---|---|---|---|
| **TAM** | $X | $Y | Top-down + Bottom-up | High/Med/Low |
| **SAM** | $X | $Y | Filtered from TAM | High/Med/Low |
| **SOM** | $X | $Y | Penetration model | High/Med/Low |

### Sizing Methodology
**Top-Down:** Step-by-step calculation from industry totals to target segment. Show every filter and assumption applied.

**Bottom-Up:** Step-by-step calculation from unit economics up. Show: (number of target customers) x (expected conversion rate) x (annual contract value).

**Reconciliation:** Comparison of both approaches, explanation of any gaps, and reconciled estimate. If they diverge by more than 3x, investigate the assumptions driving the gap.

### Growth Drivers & Trends
Key factors that could expand or contract the market -- technology shifts, regulatory changes, demographic trends, behavioral changes, and emerging adjacent segments.

### Key Assumptions & Risks
| Assumption | Impact if Wrong | Confidence | Validation Method |
|---|---|---|---|
| Description | What changes in the estimate | High/Med/Low | How to test this |

### Strategic Implications
Numbered list of what the market data means for product, pricing, and go-to-market decisions.
