An international healthcare staffing firm placed physicians into Trusts and ministries that audit every candidate. Its bought contact list could not stand up to that scrutiny. With Multiplier AI's SE platform, it moved to a 474,000-doctor universe where source and timestamp sit on every enriched field, and the records placed in front of a client could finally be traced.

The recruiter placed physicians across borders into Trusts, ministries and hospital groups. Those clients audit how candidates were identified. “We bought a list” is not an answer that passes.
The firm held a large legacy candidate database built over years by several teams. Nobody could say what proportion was still usable. The bought contact lists on top were worse: every email was presented with the same confidence, whether verified or guessed. When a client asked where a record came from, there was no audit trail to show. And a new regulatory layer had just arrived. The WHO Global Code on international recruitment was amended in May 2026, and the UK Code now names 48 red-list countries that must not be actively targeted. The firm needed to see source-country exposure at the shortlist stage, not at client review.
The real problems:
- A bought contact list that could not be defended at client audit.
- A legacy candidate database with no reliable sense of what was still live.
- Every email treated as equally verified, including the ones that were guesses.
- No visibility of source-country exposure under the WHO and UK Codes until it was too late.
The firm deployed Multiplier AI's SE platform. It is a verification-first sourcing universe built for regulated use. Four capabilities carried the work.
A 474,000-doctor universe, keyed on one identifier
Every record resolves to one doctor across identity, credentials, affiliation, publications, trials and digital footprint. Profiles are filtered by specialty, geography, experience band, publication count, trial involvement and digital presence, and ranked by data richness so the most actionable records surface first.
Provenance on every enriched value
Every enriched field stores the source it came from and the date it was written. When a Trust or ministry asked how a candidate was identified, the audit trail already existed. Enrichment filled empty fields only. The firm's own verified placement records were preserved and never overwritten.
A verification gate on contact data
Free-mail addresses were accepted only on an exact match against an authoritative page. Any address that mapped to more than one doctor was dropped entirely. The result was a smaller pool of verified email, but one the firm could defend. Unverified addresses were kept as flagged candidates, not promoted as truths.
Country-first design for code-aware recruitment
Country, state and city are first-class fields on every profile. Source-country exposure under the WHO Global Code and the UK Code was visible at the filter stage, before a list was built, rather than discovered at client compliance review.
| Scope boundary. SE surfaces the geography and provenance recruiters need to apply the WHO and UK codes. It does not maintain the red and amber lists, perform primary source verification, or assess any individual's eligibility to practise in a destination country. Those remain the recruiter's obligations. |
The firm started with the cleaning offer on 5,000 legacy records, so it could prove the method against data it already understood. The before and after was decisive, and gave the leadership team the evidence they needed to licence the universe for new sourcing.
What changed:
- Every record placed in front of a client carried a visible audit trail.
- Clinic details were filled on approximately 99.6% of records in the pilot cohort.
- A social or digital profile was found for approximately 93% of records, so approach routes no longer depended on holding an email.
- Verified email coverage settled at around 7%. Lower than the bought list claimed. Trustworthy for the first time.
- Source-country exposure under the WHO and UK Codes became visible at the filter stage, not after a client review.
| Before | After |
|---|---|
| Bought contact list with no provenance | Source and timestamp on every enriched field |
| Legacy database of unknown usability | Audit-and-impact report on 5,000-record pilot |
| Every email presented as equally verified | Verified email gate (approx. 7%), unverified flagged as candidates |
| Source-country exposure found at client review | Country on every profile, visible at the filter stage |
| Enrichment that overwrote verified data | Fill only. Original values preserved |
Why Contact Volume Loses to Provenance
Most HCP databases sold to recruiters are contact lists: a name, a specialty and an email of unknown age. SE is the opposite. It is a verification-first sourcing universe, with source and timestamp on every enriched value.
The implication is uncomfortable but useful: a smaller pool of verified contact data is worth more than a large pool of guesses, because the smaller pool is what passes client audit.
Why the 7% Verified Email Number Is a Feature
On a recent cohort, SE's verification gate accepted around 7% of email addresses, against 99.6% clinic fill and 93% social profile coverage. Most vendors would hide that figure. We lead with it.
The gate is strict by design. A free-mail address is accepted only on an exact match against an authoritative page, and any address mapping to more than one doctor is dropped entirely. The output: fewer contactable emails, far more defensible records, and alternative approach routes through digital, institutional, referral and published vacancy channels.
Country as a First-Class Field
The WHO Global Code on international recruitment was amended on 29 May 2026, and the UK Code adopts the Support and Safeguards List directly: 48 red-list countries that must not be actively targeted, plus two amber (Kenya and Nepal) where recruitment is permitted only under a government-to-government agreement.
Country, state and city sit on every SE profile. The recruiter applies its own red and amber rules at the filter stage, instead of discovering a problem at client compliance review.

Two Front Doors: Clean First, Licence Second
Most agencies start with the cleaning offer. It is cheaper, it proves the method on data they already understand, and it usually finds more placeable candidates than a new list does.
This recruiter sent 5,000 legacy records: audit, duplicate check, enrichment from public sources, and a before-and-after impact report. Approved cleaned records then loaded into SE, and the universe licence followed once the leadership team had seen the pilot report.
Built for Multi-Team Agencies
Consultants, researchers and compliance staff need different access to the same universe. SE assigns it per user rather than per licence: access scope rules (all records, selected records, or scoped by specialty, region or segment), per-user export permission, a daily record limit set by an administrator, and every gated action written to an access log.
Enrichment uses public sources only. The database is not exposed to the internet. The API is reached only through a reverse proxy over HTTPS.
We stopped selling our clients a verified email number we could not defend. SE gave us a smaller, truer pool and a story we could tell at audit.
Defensibility beats contact volume once a client starts auditing where records came from.
A smaller verified email pool with provenance is worth more than a large one that is mostly guesses.
Country as a first-class field makes WHO and UK Code exposure visible before a shortlist is built.
The cleaning pilot proves the method on data the recruiter already understands, before any universe commitment.
