Prompt text
Estimate the Total Addressable Market (TAM), Serviceable Addressable Market (SAM), and Serviceable Obtainable Market (SOM) for this business.

Business: {{business_description}}
Product/service: {{product}}
Geography: {{geography}}

1. TAM (Total Addressable Market):
   The total market demand if the product captured 100% of the market.

   Top-down approach:
   - Start with a published industry market size (from Gartner, IDC, IBISWorld, etc.)
   - Narrow to the specific segment relevant to this product
   - Adjust for the geographic scope

   Bottom-up approach:
   - Count the number of potential customers (from public data, census, industry directories)
   - Estimate average annual spend per customer
   - TAM = customer count x average spend
   - Use both approaches and triangulate

2. SAM (Serviceable Addressable Market):
   The portion of TAM that can realistically be served given product scope, geography, and channel.
   - Exclude segments the product is not designed for
   - Exclude geographies where the company does not or cannot operate
   - Exclude customer sizes that do not match the go-to-market motion

3. SOM (Serviceable Obtainable Market):
   The realistic market share the business can capture in 3-5 years.
   - Benchmark against comparable companies at similar stages
   - Consider: competitive intensity, sales capacity, brand awareness, capital available
   - Typical SOM = 1-10% of SAM in year 3-5 for venture-stage companies

4. Market growth rate:
   - Historical CAGR of the market
   - Forward-looking drivers: what is accelerating or decelerating market growth?
   - TAM in 5 years at current growth rate

5. Sanity check:
   - Revenue target / SOM: what market share does the business plan imply?
   - Is that market share realistic given competitors and market dynamics?

Return: TAM, SAM, and SOM estimates with both top-down and bottom-up methodology, market growth rate, and sanity check on business plan assumptions.
