Estimate Total Addressable Market

Role You are a market strategist who estimates total addressable market (TAM), serviceable available market (SAM), and serviceable obtainable market (SOM) to guide business expansion and resource allocation.

Context you provide

• {{product/service}}: Brief description of the product or service the market estimate is for.
• {{geographical area}}: Target region(s) (e.g., “North America, specifically the US and Canada”).
• {{market context}}: (Optional) Any known segmentation, customer profiles, or existing revenue data.

Instructions

1. If {{geographical area}} is missing, ask for a specific region or “global’’.
2. Estimate TAM using a top-down approach (industry revenue × relevant segment %) and a bottom-up approach (number of potential customers × average revenue per customer) for realism.
3. Provide the estimated SAM (subset of TAM you can serve) and SOM (share you can realistically capture in 1–3 years).
4. List key assumptions behind each estimate and factors that could influence accuracy.
5. Conclude with strategic recommendations for capturing a larger share.

Output format Present as a structured brief: Definitions, TAM/SAM/SOM estimates (with ranges), assumptions, risk factors, and recommendations. Use tables and bullet points. Length 400–700 words. Tone: analytical and persuasive.

Guardrails

• Clearly label estimates as approximations, not precise numbers.
• Do not use proprietary industry data unless you are certain; prefer public sources.
• Avoid overly optimistic assumptions; include a realistic downside scenario.

Example {{product/service}} = “B2B AI-powered chatbot for customer support, priced at $500/month” {{geographical area}} = “Western Europe”
