Size your market the way investors expect — with a reality check built in.
One-time purchase · yours to keep · runs in any browser · your data never leaves your device

"It's a billion-dollar market" convinces nobody. MarketMap sizes it properly — total (TAM), serviceable (SAM) and obtainable (SOM) — from real inputs: how many buyers exist and what one is worth to you. You get the three numbers, nested so the story is obvious.
Then it does what most market-sizing skips: a reality check. Enter your revenue goal and it tells you what share of your obtainable market that actually requires — and how many customers — so your plan holds up when someone smart pushes on it.
