Validation Thesis

This concept is only built further if tracked requests, demo clicks, or marketplace intent justify the build.

LEI and company-register lookups for fintech and marketplace workflows.
Supplier and counterparty change monitoring for review queues.
CSV/report demand from data operations and master-data teams.

Public Data Sources

The initial product would normalize public records into stable polling endpoints and exports.

GLEIF API and Golden Copy data
Companies House API
GLEIF BIC, ISIN, MIC, and OpenCorporates ID mapping files
Public company registers

Buyer Workflows

These are the specific self-serve workflows this page is testing before any backend is built.

LEI status and identity watchlist

Poll public LEI records for name, status, jurisdiction, legal-form, and source update changes tied to entities a team already tracks.

Company-register profile lookup

Resolve company names and register identifiers before routing source-linked entity records into internal tools.

Master-data enrichment

Normalize LEI, register, jurisdiction, legal form, and source evidence for products that already own business rules.

Specific Workflow Tests

These pages test sharper buyer searches before implementation.

Monetization Hypothesis

Pricing only becomes meaningful after tracked demand appears. The first offer should stay narrow and low-touch.

Validation-first CSV feed before direct payment links or entity screening workflows
Paid API tier only if entity lookup, request, or sample-download demand appears
No KYC, KYB, AML, UBO, sanctions, or final onboarding decision claims

Validation FAQ

Is this a KYC or AML decision product?

No. This is a validation page for source-linked public entity data. It does not make onboarding, verification, screening, beneficial-ownership, or compliance decisions.

Would this replace OpenCorporates, GLEIF, or company registers?

No. The proposed product would normalize a narrow set of public-source records and change events for automation. Buyers remain responsible for source checks and policy decisions.
