An AI tool that generates investor-grade TAM/SAM/SOM reports from a one-sentence startup idea
TAM // TOTAL ADDRESSABLE MARKET
SAM // SERVICEABLE ADDRESSABLE MARKET
SOM 3YR // SERVICEABLE OBTAINABLE MARKET
Real pain, but investors will ask who pays twice.
Founders hate building TAM slides, and the wedge is clear. The ceiling is lower than it looks because the best customers already pay for pitch decks, data rooms, and analyst hours, so you are fighting bundled workflows, not ignorance. You can likely bootstrap to meaningful ARR on product-led growth, but VC scale needs a path beyond one-off reports into ongoing portfolio monitoring or VC-platform distribution.
Key risk
Assumes founders buy standalone sizing instead of asking their accelerator.
SAM // SERVICEABLE ADDRESSABLE MARKET
$420M
English-first startups and indie founders reachable through self-serve.
SOM 3YR // SERVICEABLE OBTAINABLE MARKET
$18M
Three-year revenue at 0.4% of SAM through a freemium funnel.
>Methodology
TAM TOP-DOWN
The market-research software market is roughly $30B, but the honest scope here is the founder-facing sliver: fundraising preparation tooling. Narrowing to founders actively raising or planning to raise puts the ceiling near $2B.
$30B research software x 6% founder-facing = $1.8B
TAM BOTTOM-UP
Roughly 12M people worldwide are actively building or operating an early-stage startup in any given year. Comparable single-purpose founder tools price between $99 and $200 per year.
12M founders x $150/yr = $1.8B
SAM FILTERS
Self-serve distribution reaches English-first markets (55% of founder population) and only founders who pay for tooling at all (an estimated 42% of that group).
$1.8B x 55% English-first x 42% pay-for-tools = $420M
SOM BUILD
A freemium funnel converting 3% of free reports to a $149/yr plan, growing to 120k paid users by year three, implies roughly 0.4% SAM capture.
120k users x $149/yr = $18M
