# Market Research

## Overview
Market research answers the questions your gut cannot: How big is this really? Who's already here? What's coming? What do customers actually look like? This playbook gives you a repeatable system using mostly free tools. Run it before launching, and refresh quarterly.

## Step 1: Define Your Research Questions First

Never open a browser without knowing what you're looking for. Write 3-5 specific questions. Everything you find must map back to one. Examples:

- How large is the addressable market for [X]?
- Who are the top 5 competitors and what are their actual weaknesses?
- What macro or industry trends will shape this space in the next 12-24 months?
- What does a typical customer in this market look like demographically and psychographically?
- What price points do existing solutions charge, and where are the gaps?

## Step 2: Market Sizing (TAM → SAM → SOM)

You do not need exact numbers. Order-of-magnitude is enough to make decisions.

**TAM (Total Addressable Market):** Everyone on earth who theoretically has this problem or need. Often found in industry reports (Google "[industry] market size report").

**SAM (Serviceable Addressable Market):** The slice of TAM you could realistically reach given your language, geography, channel, and positioning. Apply realistic filters: "Of the global TAM, how many are in English-speaking markets? How many use the platform/channel I can reach?"

**SOM (Serviceable Obtainable Market):** What you can realistically capture in Year 1. Typically 1-5% of SAM for a new entrant.

**When no report exists — estimate from first principles:**
1. Find a related population stat (e.g. "There are 60M freelancers in the US").
2. Apply a conversion funnel: "20% use project management tools → 12M. Of those, 10% have the specific pain I'm solving → 1.2M."
3. Multiply by realistic ARPU: "If each pays $15/month → $216M TAM."
4. Sanity-check against competitor revenue if any are public.

**Decision rule:** If your realistic SOM < $500K annual revenue potential, the market is too small to sustain a solo business at a healthy margin. Consider a broader niche or higher price point.

## Step 3: Free Data Source Toolkit

**Market size & industry data:**
- Google "industry name market size" — even headline numbers from reports are useful
- Statista (free snippets give key stats)
- IBISWorld, Grand View Research — free summaries
- SEC filings of public companies in the space (revenue, growth, strategy)
- Bureau of Labor Statistics — workforce and industry employment data

**Competitive & product intelligence:**
- Competitors' websites — pricing pages, feature lists, careers pages (hiring reveals strategy), blog topics (reveals what they think matters)
- G2, Capterra, Trustpilot, App Store — read 20+ reviews minimum. Categorize complaints.
- SimilarWeb (free tier) — traffic volume and source breakdown
- Crunchbase (free tier) — funding history, investors, founding dates
- LinkedIn company pages — headcount trends (growing = healthy signal)

**Trend & signal intelligence:**
- Google Trends — search interest over time
- Reddit — search within relevant subreddits for recurring themes
- Product Hunt — what's gaining traction in adjacent spaces
- Y Combinator batch announcements — what's getting funded signals what's coming
- Twitter/X — real-time industry conversation
- Industry newsletters — find 3-5 relevant ones and read for 2 weeks before deciding
