Total addressable market work usually means stitching together exports, filters, and manual research, and the result goes stale the moment it is finished. TAM Mapping replaces that with a single flow: you describe who you sell to, Landbase builds and expands the market from your best customers, qualifies every account, and returns a sized, tiered, shareable view. This lesson walks the whole flow from an ICP description to a market your sales team can act on.
| 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 |
TAM Mapping starts by turning your ICP description into a live, structured audience rather than a static spreadsheet. You describe who you sell to, and Landbase builds a market you can expand, qualify, and refresh, so the work stays current instead of going stale.
Anchoring the model on your closed-won customers lets Landbase learn the traits that actually predict revenue. Point it at the accounts you have already won, and it scouts the lookalikes that resemble them, so the market is grounded in real outcomes rather than a guess.
From those anchors, Landbase expands into your complete addressable market and deduplicates as it goes, so you get one clean view rather than overlapping lists. The seeds set the shape, and the expansion fills it in.
A qualification sweep scores every account in the market against your criteria at once, so you are not reviewing accounts one by one. Each account carries a score you can trust, because the sweep shows the reasoning behind it.
Sizing turns the qualified market into a number you can plan against, such as how many accounts truly fit and how that breaks down by segment. This is the figure you take into planning and forecasting.
The report and ICP viewer make the market readable and shareable, so the work is not locked in your head. You can hand a colleague a view they understand at a glance.
Tiering ranks the market so the best accounts rise to the top, which is how you decide where to start. Tier 1 is where your team spends its first and best effort.
The final step delivers the tiered market to the team that will work it, in a form they can act on immediately. The motion ends with sales holding a list they trust.
