DeepTier

Where the hidden tiers are deepest.

Metal, minerals and electronics, through refiners and traders in several countries.

All industries

tier one.

DeepTier maps the suppliers behind your suppliers, down to the mine: every company, site and route, with the evidence for each link and every gap marked.

  1. Your productFinal assembly, Barcelona
  2. Tier 14 suppliers, 3 countries
  3. Tier 27 suppliers
  4. Tier 33 suppliers 1 flagged
  5. Raw materials4 sources

One graph, from your documents to the mine.

Research agents read your invoices and bills of materials, then search national registries, customs records, sanctions lists and local-language sources. Each company is anchored to its official identifier, and an analyst reviews every relationship before it reaches your map.

How DeepTier worksPublic records and your documents feed an entity graph where every company is resolved to its registry record. On top sit the route map, tier view, alerts and supplier checks. A highlighted path runs from a mine through a flagged smelter up to your product.↥ DeepTier entity graphDocuments [+] Registries [+] EvidenceMineSmelterDie-casterAssemblerPortYour productMap [+] Monitor [+] VerifyRoute mapTiersAlertsSupplier checkBusiness registriesCourt recordsOwnership filingsAnnual reportsSanctions listsExport controlsCertificationsSatellite imageryCustoms recordsBills of ladingVessel trackingInvoicesBills of materialsPurchase orders

Map

Every supplier behind your products, tier by tier, with its plants, ports and the routes to your sites.

  • Components and materials, product by product
  • Network and route maps on real geography
  • A coverage statement: what is known, and what is not

Monitor

Every company on your map is checked every day. An alert names the products it affects and what to do next.

  • Forced labour and sanctions lists
  • Export controls and changes of ownership
  • Origin, tariffs and critical materials

Verify

About to pay a new supplier? Share the quote, invoice and technical sheet. We check the company, its licences, its payment details and the factory behind it.

  • Registry record, licences and ultimate owners
  • Bank details against the company of record
  • The factory's location, and what it really makes

Walk the chain, tier by tier.

One sample product, traced from final assembly in Barcelona to the mines behind it, on real coastlines, terrain and sea lanes. Select any site to see what we know about it, and how.

Every link carries its evidence.

Each relationship is confirmed, inferred or pending, with its sources and a confidence score. Below 70%, nothing is presented as fact: it stays pending until the evidence is there.

  • ConfirmedA document or record names both companies.
  • InferredConsistent trade signals, 70% confidence or more.
  • PendingBelow 70%. Still under investigation, never shown as fact.
  • GapNot identified yet. It stays on the map as a gap.

From your documents to tier 3, in four weeks.

We do the investigation and you get the map. Agents propose, analysts decide, and your suppliers are never contacted.

  1. Week 0

    Scope

    We agree the products, components and suppliers in scope, and what a finished map means for you.

  2. Week 1

    Collect

    Your invoices and bills of materials, plus business registries, customs data, sanctions lists and local-language sources.

  3. Weeks 1–2

    Resolve

    Every company anchored to its official registry identifier. Relationships and routes reconstructed.

  4. Weeks 2–3

    Verify

    Analysts review each relationship the agents propose. Gaps go back for deeper research.

  5. Weeks 3–4

    Deliver

    Your map goes live in the platform, with a walkthrough of findings, gaps and recommended actions.

Where the hidden tiers are deepest.

We work with manufacturers that buy metal parts, motors, magnets and electronics internationally, and must answer due diligence requests from larger customers.
