Some markets publish their own membership list
A people database is built from professional profiles and company pages. It is good at software companies and poor at the markets a lot of desks live in: the organisations on a public procurement framework, NHS trusts, councils, universities, licensed professionals, trial sponsors, contractors pulling permits, local businesses in one category.
Those markets have something better than a database filter. Somebody maintains a public list of every member, by name, usually because a regulator or a framework requires it. No filter gets closer to complete than that. What the list lacks is everything a recruiter needs next: a domain, a size, and the name of the person who runs IT, data, estates or clinical operations.
This play closes that gap. It finds the register, turns the page into rows, resolves each row to a real organisation, and only then spends on people. If your market is well covered by the databases, build a target account list is the better play.
What you get back
A CSV with one row per organisation: name, type, region, official domain, the tier it landed in and why, and the register link it came from, so a colleague can check the source. For the organisations that qualified, the named decision-makers with title, LinkedIn where there is one, and work email.
Above it, three numbers: how many organisations are on the register, how many fit your desk, and how many came back with a named contact.
Variations worth knowing
Framework buyers and their technology leaders. Take the organisations entitled to buy through a public framework and find the IT and data leaders at each. It is the classic use, and the register is usually one page.
Life sciences sponsors. ClinicalTrials.gov can be searched by sponsor, condition, phase and status, including studies that are recruiting. Roll the studies up to sponsors and research organisations and you have a market map with a reason to call attached.
US construction and the trades. With your own Shovels account, permits and contractors can be pulled by place and date range, which shows who is building and how much.
Local businesses by category. With your own OpenMart account, search by category and location at store level or brand level, then find the owners.
Where this goes wrong
The register cannot be read. Logins, image-only lists and terms that forbid it all stop the extraction. The play says so and does not invent rows.
Name to domain is ambiguous. Public bodies share names, merge and trade under abbreviations. Resolution is checked before any spend, and doubtful matches are listed for you.
Registers go stale. A merged trust or a dissolved body can sit on a list for a long while. The source link stays on every row for that reason.
Spending on contacts before counting. The count and the qualification are free. Skipping them turns a proportionate spend into paying for contacts at organisations you would never call.
