Market Sizing (TAM / SAM / SOM)

What it is

TAM/SAM/SOM with sources and sanity checks. The goal is defensible order-of-magnitude, not fantasy billions.

Why it matters

Who it's for

Fundraising founders, strategists sizing new segments, and board conversations about opportunity ceiling.

• Definition of the market boundary
• Top-down and bottom-up estimates
• Sensitivity notes and citations to update

When to use it

Fundraising narrative, board discussions, and strategic pivots.

After you generate it

Footnote sources in decks, stress-test assumptions when pricing changes, and align the revenue model narrative to the same market boundaries.
