Rollcall ResearchAn AI stack, human checks, and data that holds up.
Rollcall Research works with Claude Code as the engine underneath everything: automation written to order rather than bought off a shelf. The clearest example is the assistant that runs this business day to day: it links email, calendar, Gumroad sales and a Trading 212 ISA through their APIs, so the morning position arrives as one briefing instead of five logins. That work is available in its own right, as AI implementation: finding the genuinely repetitive parts of your week and building the thing that removes them, connecting systems you already pay for and putting a model to work on the shuffling nobody wants to do.
The same setup builds the data. A UK telemarketing firm comes to us directly when a campaign needs a list that will actually connect (the school contact file, and lead-forensics datasets built to their brief) and they buy on verification: a named role, a published source page, and an honest count of what couldn't be checked. It ships as product too: Payroll Data Shield strips personal data out of text before it reaches ChatGPT or Claude and restores it in the reply, the Rollcall Ledger tracks what AI subscriptions actually cost, and a set of planners sells through Etsy and Gumroad. Read the source, label every field, show the working, whether it ends up as a dataset, a tool or an automation.
The five tabs, in the order you'll use them.
Contacts
One row per organisation: name, title, role, phone, email and the source page, so you can verify any entry yourself.
All contacts
Every contact found. If a site names two, say a Business Manager and a Facilities Manager, both are here.
Needs a phone call
No name published, but we found a direct number. Ask for the role by title and you'll get through.
Not checked
Sites that blocked us or didn't load. Listed here, not hidden, so the totals always add up.
Run log
The full figures for this run: checked, verified, inferred, by role. Nothing rounded off.
We read each organisation's own website. That's the whole method.
Start from the public register
For schools, that's the Department for Education's list of every school and its website. Other sectors have their own: the CQC for care homes, the Charity Commission for charities, Companies House for hotels.
Work through each site
Staff, contact and leadership pages. We respect robots.txt and skip sites that ask not to be visited, listing them separately.
Identify the named roles
We record the job title exactly as published. If no target role is named, we give a labelled fallback contact instead.
Label every address and deliver the workbook
Every address is labelled verified, inferred or absent, with its source page. We reconcile the totals against the register before sending anything.
