Knowing your total addressable market is the difference between planning against a real number and guessing. The usual way to size it, with exports and filters and manual research, is slow and stale the moment it is finished. TAM Mapping treats your market as something living instead: you describe who you sell to, and Landbase builds it, qualifies it, and keeps it current, so the picture your team plans against reflects the market as it is now.
| Tier | Accounts | Examples |
|---|---|---|
| Tier 1 | 180 | Acme, Globex, Initech |
| Tier 2 | 540 | Hooli, Vehement, Soylent |
| Tier 3 | 1,200 | and the rest of the qualified market |
Describe your ICP and turn it into a live, structured audience rather than a static spreadsheet.
Anchor the model on your closed-won customers, so Landbase learns the traits that actually predict revenue.
Expand from those anchors into your complete addressable market, deduplicated as it goes.
Run a qualification sweep that scores every account against your criteria at once, instead of reviewing them by hand.
Turn the qualified market into a number you can plan against, such as how many accounts truly fit.
Use the report and ICP viewer to make the market readable and shareable, so the work is not locked in your head.
Tier the market so the best accounts rise to the top, which is how you decide where to start.
Deliver the tiered market to the team that will work it, in a form they can act on immediately.
