How big is the opportunity, really?OTS

Size your market the way investors and partners expect it — total, serviceable, and obtainable — then reality-check it against the revenue you actually want. No hand-waving "it's a billion-dollar market."

Your market

Start with how many buyers exist and what one is worth to you per year.

Total potential buyers in the market (everyone who could ever buy)

Average annual revenue per customer (ACV)

Share you can actually serve (right segment, geography, product fit)

Share of that you can realistically win (in ~3–5 yrs)

Your annual revenue goal (the reality check)

Your market, sized

TAM → SAM → SOM, in annual revenue.

TAM · Total market—

Every possible buyer × what one is worth.

SAM · Serviceable—

The slice you can actually reach and serve.

SOM · Obtainable—

What you can realistically win near-term.

Reality check — your revenue goal vs. what's obtainable

—

Enter a revenue goal to test it against your obtainable market.
