TAM mapping & prospecting data
Define the ICP, map the whole market, and capture it as scored, ready-to-work data.
Your real total addressable market is larger than any database shows. Single-source tools cap at 78–84% coverage on mainstream B2B and far less everywhere else, so most teams plan against a fraction of their market. Datum maps and captures your entire TAM: we define the ICP, source it at the origin, enrich through a waterfall past 90% match, and score every account so reps work the ones most likely to close. Only 27% of leads handed to sales are actually qualified — scoring fixes that before a rep ever works the account.
Map the whole market, not the indexed slice
Off-the-shelf databases return what they happen to catalog — strong for mainstream software, thin for the trades, regional operators, niche verticals, and net-new categories. Sizing your market from one of them quietly undercounts most of your buyers.
We start from the system of record for your category — directories, registries, marketplaces, filings — and capture the full account population, deduped into a TAM you can actually plan territories against.
- ICP definition tied to who actually closes
- Sourcing at the origin, not a reseller's index
- Scraping the directories and registries databases skip
- Waterfall enrichment to 90%+ match
Score it so reps work the right accounts
A list isn't a pipeline. We score every account and contact — fit, intent signals, and machine-learning models trained on what has closed for you — so the highest-probability accounts surface first.
Machine-learning scoring reaches 40–60% accuracy versus 15–25% for rule-based models, and converts up to 75% better. Reps stop guessing which leads matter.

Common questions
During scoping we estimate the market from the structure of its source records, then refine it once sourcing runs. You see the methodology, not just a headline number.
We source publicly available information and respect each source's terms and rate limits. We don't bypass authentication or resell another vendor's licensed database. Scope and compliance are part of the discovery call.
