Capturing the TAM databases miss
If your model says 40,000 accounts but your database surfaces 4,000, the gap isn't your market — it's the index's blind spot. Mainstream tools cap at 78–84% coverage on well-documented segments and far less elsewhere, so any sizing built on them undercounts. Datum maps and captures your entire real TAM from primary sources — registries, directories, marketplaces — dedupes it into a defensible account universe, and scores it. You get a market you can plan territories against and show a board, not a number that quietly excludes most of your buyers.
Market sizing pulled from a single database inherits that database's gaps. For mainstream software that's tolerable. For most other markets it means your "TAM" is really "the slice one vendor happened to catalog."
When that number drives territory planning, quota, and fundraising, the undercount has real consequences. Capturing the full population at the source fixes the input — and scoring it tells you which slice to work first.
This is you if…
- TAM vs. reality gapThe market is obviously bigger than what your tools return.
- Territory planning stallsReps run out of named accounts that clearly exist in the wild.
- The number won't defendYour addressable market can't be justified past the database it came from.
How we handle it
- 01We identify the authoritative sources for your category and capture the account population directly, not through a reseller's index.
- 02Then we dedupe, normalize, enrich, and score it into a working account universe — firmographics, segments, and a fit score — delivered into your CRM or warehouse.
Common questions
We can usually give a defensible first estimate from the source structure during scoping, then refine it once capture runs. You see the methodology, not just a headline number.
