Company Lens bridges the gap between a registered UK company and its real-world web presence.

Given a company name or registration number, it queries the Companies House API, runs a two-stage LLM pipeline to infer and verify likely domain names, and produces an auditable, ranked result with full diagnostic data.

How it works

CH API → LLM Inference → Verification → LLM Ranking → Persisted Dataset

Stage 1 — Inference
The Companies House profile is sent to an LLM which generates up to 5 candidate domain names, accounting for UK trading name conventions, international brand patterns, SIC industry codes, and company type.

Stage 2 — Verification
Each candidate is checked in parallel across DNS, HTTPS, SSL, WHOIS, and content signals. Redirect chains are followed automatically — if selcobuilders.co.uk redirects to selcobw.com, the redirect target is promoted to a new candidate and verified in its own right.

Stage 3 — Ranking
A second LLM call re-ranks all verified candidates using explicit decision rules, flagging squatted or parked domains and identifying the canonical primary domain.

Every candidate has a reasoning field, a signal breakdown, and a full audit trail. The goal is explainability — you can see why the answer is what it is, not just what it is.

Why it exists

Most domain enrichment tools are black boxes. Company Lens is different. Every lookup produces a labelled result — making the dataset compound in value over time as a training resource for future projects.
